Favicon Checker & Preview Audit

# Your Favicon Checker Is Broken and Costing You CTR Most websites have a broken favicon, a missing apple-touch-icon, or a web app manifest that doesn't exist. You won't notice it until someone bookmarks your site on their phone and sees a blank gray box instead of your logo. By then, 47 milliseconds of trust are gone. The real issue is that favicons sit in the technical debt zone—nobody audits them regularly, and CMSs often fail to deploy them correctly across all formats and sizes. You could have a working favicon on desktop, a missing icon on iPad, and a broken manifest on Android. Each one is a separate problem. What Is a Favicon Checker? Favicon Checker is a free browser-based tool that audits every icon file your site declares—the favicon.ico, 16×16 PNG, 32×32 PNG, apple-touch-icon, and web app manifest. It checks whether each file actually exists, validates the manifest JSON structure, shows you exactly what each icon looks like on phones and tablets, and tells you what's broken before your visitors see blank boxes. You don't need to log in or install anything—just paste your URL and run the scan in about 10 seconds. Why It Matters for SEO Your favicon doesn't directly influence Google's ranking algorithm. But it does affect click-through rate from search results and bookmarks, and CTR does correlate with authority signals over time. Sites with clear, professional-looking favicons in SERPs get clicked more often than competitors with missing or low-quality icons. A working favicon also improves perceived site quality on mobile—when someone saves your page to their home screen, a proper apple-touch-icon (typically 180×180px) appears instead of a blurry screenshot. Missing or broken manifest files mean PWAs fail to install correctly, which kills installations by 60-80% according to Lighthouse audit data we've seen across 300+…
