Favicon Checker
Check whether a site exposes a real favicon setup before launch. We look for icon tags, fallback favicon paths, and format coverage so founders can catch the small branding issues that make a site look unfinished.
Icon tag detection
Checks linked favicon declarations in the document head.
Fallback coverage
Tests whether the default /favicon.ico path exists.
Launch advice
Returns practical recommendations for what to improve next.
Part of the checklist
Use this before launch
This checker is part of our broader startup launch SEO checklist. After favicon setup, the natural next checks are Open Graph previews, metadata, sitemap discovery, and structured data.
Read the full launch checklistWhat is a favicon?
A favicon is the small icon displayed in a browser tab, bookmark bar, and link preview next to your site name. It is declared in your HTML head using link rel="icon" tags and served from your domain — most commonly as a /favicon.ico fallback combined with modern SVG and PNG variants.
Why it matters for your launch
A missing or broken favicon makes a site look unfinished. When someone opens your startup alongside ten other browser tabs, your icon is the only persistent identifier they see. Directory listings, product review pages, and social bookmarks all display favicons — a blank icon signals that the site is still in development. This checker catches those issues before your first visitor sees them.
What formats should I include?
A complete setup includes favicon.ico at the root for older browsers, a PNG variant for broad compatibility, and an SVG icon for high-resolution displays.
Why does a favicon matter for branding?
It is one of the few brand assets visible across every browser tab, bookmark folder, and link preview. A polished icon reinforces trust at first glance.
How do I add a favicon?
Place your favicon files at the site root and add link tags in your HTML head, e.g. <link rel='icon' href='/favicon.ico'> and <link rel='icon' type='image/svg+xml' href='/favicon.svg'>.
Does a favicon affect SEO?
Not directly, but it affects perceived credibility. Directory listings and search result snippets sometimes display favicons, so a missing one can reduce click-through rates.
