Favicon Generator: Create Perfect Website Icons in Seconds 

What Is a Favicon and Why Does Your Website Need One?

A favicon (short for "favorite icon") is the small, branded icon that appears in browser tabs, bookmarks, and address bars when visitors access your website. While it may seem like a minor detail, this tiny 16×16 or 32×32 pixel image plays a crucial role in your website's professional appearance, brand recognition, and overall user experience.

In today's competitive digital landscape, every element of your website matters. A well-designed favicon helps users quickly identify your site among dozens of open tabs, builds brand consistency, and signals professionalism to both visitors and search engines. Studies show that websites with custom favicons experience up to 23% better brand recall compared to those using default browser icons.

The SEO Impact of Favicons You Can't Ignore

Many website owners underestimate the indirect SEO benefits of having a properly optimized favicon. While Google has confirmed that favicons don't directly impact rankings, they significantly influence user behavior metrics that search engines track closely.

How Favicons Affect Your SEO Performance:

Brand Recognition in SERPs: Since 2019, Google displays favicons in mobile search results. A distinctive, recognizable favicon increases click-through rates by making your listing stand out from competitors. Higher CTR signals to Google that users find your content relevant, potentially boosting your rankings.

Reduced Bounce Rate: Users who can easily identify your site in their browser tabs are more likely to return to it, reducing bounce rates. When implementing a comprehensive website audit checklist, favicon optimization should be a priority.

Professional Credibility: Websites without favicons appear unfinished or unprofessional. This perception affects trust signals, which indirectly impact how users interact with your site—a factor search engines monitor through behavioral metrics.

Mobile User Experience: As mobile SEO optimization becomes increasingly critical, favicons help users navigate between apps and browser tabs on smaller screens, improving mobile experience scores.

Understanding Favicon Specifications and Requirements

Creating a favicon isn't as simple as shrinking your logo. Different browsers, devices, and platforms require specific formats and sizes for optimal display.

Essential Favicon Formats

ICO Format (Classic): The traditional .ico format remains the most universally supported across all browsers. It can contain multiple sizes within a single file, making it ideal for backward compatibility.

PNG Format (Modern): PNG favicons offer better compression and transparency support. They're particularly important for high-resolution displays and modern browsers.

SVG Format (Future-Ready): Scalable Vector Graphics provide infinite scalability without quality loss, perfect for responsive design. However, browser support is still limited compared to ICO and PNG.

Critical Favicon Sizes for 2025

• 16×16 pixels: Standard browser tab icon
• 32×32 pixels: Enhanced resolution for modern displays
• 48×48 pixels: Windows site icons
• 64×64 pixels: High-DPI displays
• 128×128 pixels: Chrome Web Store
• 180×180 pixels: Apple Touch Icon for iOS devices
• 192×192 pixels: Android home screen icon
• 512×512 pixels: Progressive Web App splash screens

<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">

For WordPress users, you can also detect and optimize your theme using our WordPress Theme Detector to ensure compatibility.

Advanced Favicon Design Best Practices

Creating an effective favicon requires understanding design principles that work at microscopic scales.

Color Psychology and Contrast

At tiny sizes, color becomes your primary communication tool. High-contrast color combinations ensure visibility across different backgrounds. Avoid subtle gradients or similar color tones that blend together when scaled down.

Winning Color Combinations:

• Navy blue and white (tech/corporate)
• Red and white (energy/action)
• Green and white (health/eco)
• Black and yellow (visibility/warning)
• Purple and white (luxury/creativity)

Simplicity Wins

Your favicon should communicate your brand instantly. Limit your design to one or two key elements. If your logo contains text, consider using just the initial letter or a simplified icon representation. Complex logos with multiple elements become unreadable blobs at 16×16 pixels.

Test Across Backgrounds

Your favicon appears on various backgrounds—light browser tabs, dark bookmarks bars, and colored mobile screens. Test your design on white, black, and gray backgrounds to ensure consistent visibility. Our Screen Resolution Simulator helps preview how your favicon appears across different devices.

Maintain Brand Consistency

While favicons require simplification, they must remain recognizable as part of your brand identity. Use your primary brand colors and extract the most distinctive element from your full logo. This consistency reinforces brand recognition across all digital touchpoints.

Technical Implementation: Beyond the Basics

Proper favicon implementation extends far beyond dropping an icon file in your root directory. Modern web standards require comprehensive setup for optimal functionality.

HTML5 Favicon Declaration

Modern browsers support multiple favicon declarations, allowing you to specify different icons for various contexts:

<!-- Standard favicon -->
<link rel="icon" href="/favicon.ico" sizes="any">
<link rel="icon" href="/favicon.svg" type="image/svg+xml">

<!-- Apple iOS -->
<link rel="apple-touch-icon" href="/apple-touch-icon.png">

<!-- Android Chrome -->
<link rel="manifest" href="/manifest.json">

<!-- Microsoft Windows -->
<meta name="msapplication-TileColor" content="#da532c">
<meta name="msapplication-config" content="/browserconfig.xml">

Progressive Web App Integration

If you're building a Progressive Web App, your favicon plays a crucial role in the home screen icon experience. Create a complete icon set ranging from 72×72 to 512×512 pixels, and reference them in your web app manifest file.

Cache Control Considerations

Browsers aggressively cache favicons, which can be problematic during updates. Implement proper cache control headers and version your favicon files when making changes:

<link rel="icon" href="/favicon.ico?v=2">

For comprehensive site performance, check your GZIP compression settings and run a complete website SEO score analysis alongside favicon implementation.

Common Favicon Mistakes That Hurt Your Brand

Even experienced developers make favicon errors that diminish their website's professional appearance.

Using Low-Resolution Images

Uploading a 16×16 pixel image and expecting it to scale up for mobile devices results in pixelated, unprofessional icons. Always start with high-resolution source images and generate down, never up.

Ignoring Dark Mode

With dark mode adoption exceeding 70% among mobile users, favicons designed only for light backgrounds become invisible or ugly on dark interfaces. Design with both modes in mind, or create separate favicons for each preference.

Forgetting Mobile Icons

Many developers focus solely on the classic 16×16 favicon while neglecting the 180×180 Apple Touch Icon and 192×192 Android icon. Mobile traffic now exceeds desktop for most websites, making these icons equally critical.

Skipping File Optimization

Unoptimized favicon files waste bandwidth and slow page load times. While a single favicon seems trivial, multiply it by millions of page views, and the impact becomes significant. Use our Image Compressor to optimize all your website graphics, including favicons.

Using Trademarked or Copyright-Protected Images

Creating a favicon from copyrighted material exposes you to legal risk. Always use original designs or properly licensed images. Need inspiration? Our Reverse Image Search helps verify image originality.

Platform-Specific Favicon Requirements

Different platforms and applications have unique favicon requirements beyond standard web browsers.

WordPress Favicon Setup

WordPress 4.3+ includes built-in favicon support through the Customizer (Appearance → Customize → Site Identity). However, for comprehensive control, manual implementation via functions.php or header.php provides more flexibility. After uploading your favicon, verify implementation using our WordPress Theme Detector.

Shopify Favicon Guidelines

Shopify automatically resizes uploaded favicons to 32×32 pixels. Upload a minimum 512×512 pixel square PNG for best results. Access the favicon uploader through Online Store → Themes → Customize → Theme Settings → Favicon.

Social Media Platform Icons

Each social platform has specific requirements:

Facebook: Uses the Open Graph image when shared, but your favicon appears in browser tabs when users visit your page. Generate proper metadata using our Open Graph Generator.

Twitter: Similarly relies on Twitter Cards for shared content but displays your favicon in browser contexts. Create optimized tags with our Twitter Card Generator.

LinkedIn: Pulls favicon automatically when users share your content, making consistent branding across all touchpoints essential.

Troubleshooting Common Favicon Issues

Even with proper implementation, favicon problems occasionally arise. Here's how to diagnose and fix them.

Favicon Not Appearing

Clear Browser Cache: Browsers cache favicons aggressively. Hard refresh (Ctrl+Shift+R) or clear browser cache to force reload.

Check File Path: Verify the favicon file exists at the specified location. Use absolute URLs in development to avoid path issues.

Validate HTML Syntax: Incorrect link tag syntax prevents favicon loading. Use our Online HTML Viewer to check your code.

Review Server Headers: Ensure your server sends correct Content-Type headers for favicon files. Use our HTTP Header Checker to diagnose server configuration issues.

Wrong Favicon Displaying

Version Cache Issue: Add version query parameters to force browsers to fetch the updated file: favicon.ico?v=2

Multiple Declarations Conflict: Remove duplicate or conflicting favicon declarations from your HTML head section.

CDN Caching: If using a CDN, purge the cache after updating your favicon to propagate changes globally.

Mobile Favicon Problems

Missing Platform-Specific Icons: iOS requires 180×180 Apple Touch Icon while Android needs 192×192. Missing these results in fallback to standard favicon, which renders poorly.

Incorrect Manifest Configuration: Verify your web app manifest correctly references all icon sizes and paths.

Color Scheme Conflicts: Test your favicon on both light and dark mobile interfaces to ensure visibility.

Favicon Security Considerations

While often overlooked, favicons present potential security vectors that require attention.

Favicon-Based Tracking

Researchers have demonstrated favicon-based tracking techniques that exploit browser caching behavior. While primarily a privacy concern rather than a security threat, be aware that sophisticated tracking can occur through favicon manipulation.

Cross-Site Request Forgery

In rare cases, improperly configured favicon implementations can be exploited for CSRF attacks. Always serve favicons from your domain and implement proper CORS headers.

Content Security Policy

Include favicon sources in your Content Security Policy to prevent unauthorized favicon injection attempts. Monitor your site security using our SSL Checker.

Future of Favicons: Emerging Trends

The humble favicon continues evolving with new technologies and user expectations.

Animated Favicons

Some modern browsers support animated favicons using GIF or animated PNG formats. While not universally supported, animated favicons grab attention in crowded tab bars. Use sparingly to avoid distraction.

Dynamic Favicons

Progressive Web Apps enable dynamic favicon changes based on application state (unread messages, notifications, loading status). This functionality requires JavaScript and manifest configuration.

Dark Mode Adaptive Icons

CSS now supports prefers-color-scheme media queries for favicons, allowing automatic switching between light and dark versions:

<link rel="icon" href="/favicon-light.png" media="(prefers-color-scheme: light)">
<link rel="icon" href="/favicon-dark.png" media="(prefers-color-scheme: dark)">

High DPI Display Optimization

With 4K and 5K displays becoming standard, providing multiple resolution favicons ensures sharp rendering across all screen densities.

Creating Favicons for Different Industries

Different industries benefit from specific favicon design approaches that align with their brand identity and user expectations.

E-Commerce Favicons

Online stores should prioritize recognizable brand symbols or shopping-related icons. Consider incorporating your logo's most distinctive element or a simplified shopping bag icon. Ensure high contrast for visibility across product pages and checkout flows. Learn more about optimizing your e-commerce store for better conversions.

SaaS and Tech Company Favicons

Software companies typically opt for geometric, minimalist designs that convey innovation and professionalism. Abstract shapes, letter marks, or simplified app icons work exceptionally well. Keep designs clean and modern to reflect your technical expertise.

Blog and Content Site Favicons

Content-focused websites benefit from letter-based favicons using the site's initial or a simple icon representing their niche. Photography blogs might use a camera icon, while cooking sites could feature a chef's hat or utensil symbol.

Local Business Favicons

Restaurants, law firms, and medical practices should use easily recognizable symbols from their industry—a fork and knife, scales of justice, or medical cross. Include your primary brand color for instant recognition.

Favicon Optimization for Core Web Vitals

Favicons impact your site's Core Web Vitals, particularly Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS).

Reducing Favicon File Size

Compress your favicon files aggressively without sacrificing quality. A 16×16 pixel favicon should never exceed 1-2 KB. Use our Image Compressor to achieve optimal compression ratios.

Implementing Lazy Loading

While favicons load early in the page lifecycle, ensuring they're properly cached prevents unnecessary reloads. Set long cache expiration headers (minimum 1 year) to reduce HTTP requests on repeat visits.

Preloading Critical Favicons

For high-traffic sites, consider preloading your favicon to improve perceived performance:

<link rel="preload" href="/favicon.ico" as="image">

This technique works best when combined with other speed optimization strategies.

Favicon Accessibility Considerations

Accessibility often gets overlooked in favicon design, but it matters for users with visual impairments and assistive technologies.

Color Contrast Requirements

While WCAG guidelines don't specifically cover favicons, applying contrast principles improves visibility for users with color blindness or low vision. Maintain a contrast ratio of at least 3:1 between your favicon's foreground and background elements.

Meaningful Icons Over Text

Small text becomes illegible at favicon sizes and creates accessibility barriers. Icons and symbols provide universal understanding regardless of language or reading ability.

Testing with Grayscale

Convert your favicon to grayscale to ensure it remains distinguishable for users with color vision deficiencies. If your design relies solely on color differentiation, it needs refinement.

Integrating Favicons with Brand Guidelines

Your favicon should seamlessly integrate with your broader brand identity system.

Extracting Favicon Elements from Logos

Start with your full logo and identify the most recognizable element—typically a symbol, icon, or first letter. This element should work independently while maintaining clear connection to your brand.

Maintaining Color Consistency

Use exact color values from your brand palette. Even slight color variations between your logo and favicon create inconsistency that weakens brand recognition. Reference your brand style guide when designing.

Adapting for Different Contexts

While maintaining brand consistency, adapt your favicon for optimal legibility. Sometimes this means simplifying shapes, increasing contrast, or adjusting colors that work in print but fail at digital micro-sizes.

Advanced Favicon Implementation Techniques

Take your favicon strategy beyond basics with these advanced implementation methods.

SVG Favicons with CSS Styling

Modern browsers support SVG favicons that can be styled with CSS, enabling dynamic color changes based on user preferences:

<link rel="icon" href="/favicon.svg" type="image/svg+xml">

Your SVG can include CSS that responds to dark mode:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
  <style>
    path { fill: #000; }
    @media (prefers-color-scheme: dark) {
      path { fill: #fff; }
    }
  </style>
  <path d="..."/>
</svg>

Favicon Badge Notifications

Progressive Web Apps can dynamically update favicons to display notification badges, unread counts, or status indicators. This requires JavaScript and the Canvas API to programmatically generate favicon images.

Animated Favicons for User Engagement

Create subtle animations that draw attention during loading states or important events. Keep animations minimal—excessive movement annoys users and drains battery on mobile devices.

let link = document.querySelector("link[rel~='icon']");
let frames = ['/favicon1.ico', '/favicon2.ico'];
let frame = 0;

setInterval(() => {
  link.href = frames[frame++ % frames.length];
}, 500);

Common Questions About Our Favicon Generator

How Many Formats Should I Generate?

Generate at minimum: one .ico file (containing 16×16 and 32×32), PNG files for standard sizes, and an Apple Touch Icon. Our tool automatically creates all necessary formats in one click.

Can I Use Photographs as Favicons?

While technically possible, photographs rarely work well as favicons. The extreme size reduction turns photographic details into muddy blobs. Stick with graphic designs, logos, or simplified icons for best results.

Should I Match My Logo Exactly?

Not necessarily. Your favicon should be recognizable as part of your brand but may need simplification. If your logo contains fine details or text, extract the most distinctive element rather than shrinking everything proportionally.

How Often Should I Update My Favicon?

Update your favicon when rebranding or when your design looks outdated compared to modern web standards. Most favicons remain effective for 3-5 years unless your brand identity changes.

Real-World Favicon Success Stories

Understanding how major brands leverage favicons provides valuable insights for your own implementation.

Tech Giants

Google's multicolor "G", Amazon's smile arrow, and Netflix's red "N" demonstrate the power of ultra-simple, instantly recognizable favicons. These companies understand that at 16×16 pixels, complexity fails while simplicity succeeds.

E-Commerce Leaders

Shopify's shopping bag and Etsy's "E" in their signature font show how e-commerce platforms balance brand identity with functional clarity. Both remain distinguishable even among dozens of open tabs.

Media Organizations

The New York Times uses its distinctive "T" logo, while Medium employs its simple "M" lettermark. News and content platforms prove that typography-based favicons work when properly executed.

Troubleshooting Favicon Display Issues Across Platforms

Different platforms present unique challenges that require specific solutions.

iOS Safari Issues

iOS Safari caches favicons aggressively. After updating, users may see old versions for weeks. Solutions include:

• Clear Safari cache completely
• Add version parameter to Apple Touch Icon URL
• Wait for iOS to naturally refresh (up to 30 days)

Chrome Incognito Mode Problems

Chrome's incognito mode uses more aggressive caching. Test favicon updates in regular browsing mode first, then verify in incognito after clearing all browsing data.

Firefox Multiple Profile Challenges

Firefox users with multiple profiles may see different favicons in each profile due to separate cache systems. Ensure long cache headers are set to maintain consistency.

Edge Compatibility Concerns

Microsoft Edge displays favicons differently than Chrome despite sharing the Chromium engine. Always test both browsers independently to catch platform-specific rendering issues.

Frequently Asked Questions (FAQs)

What is a favicon and why do I need one?

A favicon is a small 16×16 or 32×32 pixel icon that appears in browser tabs, bookmarks, and address bars. You need one because it enhances brand recognition, improves user experience by helping visitors identify your site among multiple tabs, and adds professional credibility. Sites without favicons appear unfinished and amateur, negatively impacting user trust and engagement metrics.

What's the best size for a favicon in 2025?

The best approach is to provide multiple sizes rather than one "best" size. Create these essential sizes: 16×16 and 32×32 pixels for browser tabs, 180×180 pixels for Apple devices, 192×192 and 512×512 pixels for Android, and 48×48 pixels for Windows. Our Favicon Generator automatically creates all required sizes from a single uploaded image.

Should I use ICO, PNG, or SVG format for my favicon?

Use all three formats for maximum compatibility. ICO format provides the best backward compatibility with older browsers, PNG offers superior compression and is widely supported by modern browsers, and SVG delivers infinite scalability for future devices. Implement all formats using conditional links in your HTML head, allowing each browser to choose its preferred format.

How do I add a favicon to my website?

Upload your favicon files to your website's root directory, then add this code to your HTML <head> section:

<link rel="icon" type="image/x-icon" href="/favicon.ico">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

For WordPress sites, use the built-in customizer or manually add files to your theme. Verify implementation with our WordPress Theme Detector.

Why isn't my favicon showing up after uploading it?

Browser caching is the most common cause. Try these solutions: hard refresh your browser (Ctrl+Shift+R or Cmd+Shift+R), clear your browser cache completely, verify the file path is correct, check that your HTML link tags use proper syntax, ensure the file exists at the specified location, and add a version parameter to force reload (favicon.ico?v=2). Use our HTTP Header Checker to diagnose server configuration issues.

Do favicons affect SEO rankings?

Favicons don't directly impact search rankings, but they significantly influence user behavior metrics that search engines track. Google displays favicons in mobile search results, which increases click-through rates when your icon is distinctive and professional. Higher CTR signals relevance to Google, potentially boosting rankings. Additionally, favicons reduce bounce rates by helping users identify and return to your tab, another positive ranking signal.

Can I use my logo as a favicon?

Yes, but you'll likely need to simplify it. Full logos often contain too much detail to remain legible at 16×16 pixels. Extract the most recognizable element—typically a symbol, icon, or first letter—rather than shrinking your entire logo. Test your design at actual size to ensure it remains clear and identifiable before implementing it.

What file format does Apple use for favicons?

Apple iOS devices use the Apple Touch Icon format, which is a PNG file sized at 180×180 pixels. Name it apple-touch-icon.png and reference it in your HTML head:

<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

This icon appears when users save your site to their home screen, making it crucial for mobile branding.

How do I create a favicon without design skills?

Use our free Favicon Generator tool—simply upload any square image, and it automatically creates optimized favicons in all required sizes and formats. Alternatively, start with basic shapes, your brand's first letter, or simple icons relevant to your industry. Focus on high contrast and simple designs rather than complex artwork. You can also use our Text to Image tool to create letter-based favicons.

Do I need different favicons for light and dark mode?

It's highly recommended for optimal user experience. Over 70% of mobile users prefer dark mode, and favicons designed only for light backgrounds may become invisible or ugly on dark interfaces. Create two versions—one optimized for light backgrounds and another for dark—then implement them using media queries:

<link rel="icon" href="/favicon-light.png" media="(prefers-color-scheme: light)">
<link rel="icon" href="/favicon-dark.png" media="(prefers-color-scheme: dark)">

How long does it take for favicon changes to appear?

Browsers cache favicons aggressively, so changes may take hours to days depending on cache settings. For immediate testing, hard refresh your browser or use incognito mode. To force updates for all users, add a version parameter to your favicon URL (favicon.ico?v=2). If using a CDN, purge the cache after updating. Expect 24-48 hours for changes to propagate fully across all users and platforms.

What's the difference between favicon.ico and PNG favicons?

ICO is an older Microsoft format that can contain multiple sizes in one file and enjoys universal browser support, including legacy versions. PNG is a modern format with better compression, superior transparency support, and smaller file sizes, but requires separate files for each size. Best practice: use both formats for maximum compatibility—ICO for older browsers and PNG for modern ones.

Can favicons be animated?

Yes, some modern browsers support animated favicons using animated GIF or APNG (Animated PNG) formats. However, browser support is inconsistent, and excessive animation can annoy users and drain mobile battery. Use animation sparingly—perhaps for loading states or notification alerts—rather than constant motion. Test thoroughly across browsers before implementing animated favicons on production sites.

How do I test my favicon on different devices?

Use our Screen Resolution Simulator to preview how your favicon appears on various devices. Additionally, test on actual devices when possible: check iOS Safari, Android Chrome, desktop browsers (Chrome, Firefox, Safari, Edge), and verify appearance on both light and dark browser themes. Our What Is My Browser tool helps identify which browsers your audience uses most.

Is it possible to have multiple favicons for different pages?

Technically yes—you can declare different favicons in each page's HTML head section. However, this approach confuses users and weakens brand recognition. Consistency across your entire website builds stronger brand identity. The only exception might be major site sections or subdomains that function as distinct brands, but even then, maintaining one unified favicon is generally recommended.

What happens if I don't have a favicon?

Browsers display a generic blank page icon or default browser icon, which makes your site look unprofessional and amateur. Users struggle to identify your site among multiple open tabs, leading to lower return engagement. In mobile search results, Google shows a placeholder icon instead of your brand, reducing your listing's visual appeal and click-through rate. The absence of a favicon sends a negative signal about attention to detail and brand professionalism.

How do favicons work with Progressive Web Apps?

PWAs require comprehensive icon sets ranging from 72×72 to 512×512 pixels for various contexts: home screen icons, splash screens, and app switchers. Define these in your web app manifest file (manifest.json). Higher resolution icons are critical for PWAs because they appear much larger than traditional browser favicons. Ensure your icons look sharp at all sizes and maintain brand consistency across all PWA touchpoints.

Can I use emoji as favicons?

While technically possible by converting emoji to image format, it's generally not recommended. Emoji render differently across operating systems and browsers, causing inconsistent brand presentation. Additionally, emoji are often too detailed to remain clear at 16×16 pixels. If you want an emoji-style favicon, create a custom, simplified version that maintains consistency across all platforms.

Do I need to update my favicon regularly?

Only update when rebranding, when your design looks outdated compared to modern web standards, or when user feedback indicates poor visibility or recognition. Most effective favicons remain unchanged for 3-5 years. Frequent changes confuse users and weaken brand recognition. Focus on creating a timeless design initially rather than planning regular updates.

What's the ideal color palette for favicons?

Use 2-3 colors maximum for optimal clarity at small sizes. Choose high-contrast combinations: dark colors on light backgrounds or vice versa. Avoid gradients and subtle color transitions that muddy when scaled down. Stick to your brand's primary colors for recognition, but adjust saturation or brightness if needed for better small-size legibility. Test your palette on both white and black backgrounds.

How do search engines use favicons?

Google displays favicons in mobile search results since 2019, making them visible branding elements in SERPs. Search engines also use favicons to identify and categorize websites, though this doesn't directly impact rankings. Favicons appear in browser history, bookmarks, and reading lists—all contexts where clear branding improves click-through rates and user engagement, indirectly benefiting SEO performance.
