Favicon Checker by Traffsite

A favicon checker inspects the icon a site declares for search results and browser tabs. The Traffsite favicon checker reads the link element, follows the href to the file and reports the format, dimensions, aspect ratio, response code and rel value.

Google's guidance is specific:

• Shape: square, with a 1:1 aspect ratio.
• Size: at least 8x8 pixels, and Google recommends larger than 48x48 so the icon holds up on different surfaces.
• Formats: BMP, GIF, ICO, PNG, JPEG, PPM and TIFF.

The tool also looks at placement. Google reads the link element with rel values such as icon, shortcut icon, apple-touch-icon and apple-touch-icon-precomposed. The href can be relative or absolute and does not have to sit on your own domain. What matters is that the address resolves and stays stable.

One limit belongs upfront: Google may show a favicon in search results, but it does not guarantee one, even when every guideline is met. A checker can confirm eligibility and remove obstacles, but do not promise the icon will appear.

• After a rebrand. A new logo often reaches the header first and the favicon last. The checker confirms the old file is not still in place.
• Before a launch. A missing or broken icon makes a new site look unfinished in a tab or bookmark.
• After a domain or hosting change. The icon URL may have moved, or the file may now return a 404.
• When search results show the wrong image. The checker separates a favicon problem from a caching delay or a crawl block.
• On sites with several subdomains. Each hostname can declare its own icon.

The main help is certainty about an easy-to-miss detail. A favicon is a small file with a short set of rules, but those rules touch image format, dimensions, HTML, crawl access and timing.

A tab icon can come from a cached file while Google sees something else, because Googlebot and Googlebot-Image follow their own access rules. If the home page or the icon is blocked from crawling, the icon cannot be processed for search even when it loads for a visitor. The checker points at the blocked resource instead of leaving you to guess.

For a team, the report is a shared reference. A designer can confirm the file is square and large enough, a developer can confirm the link tag and response code, and a content lead can confirm the change was intentional.

The report shows a preview of the icon, the declared link tag, the file's format, dimensions and aspect ratio, its response code, and the crawl status of both the home page and the icon file. Each item is marked as passing, a warning or a blocker, so you know what to fix first.

The aim is an icon setup that is eligible, stable and easy to maintain: one clear file per hostname, a link tag Google can read, a stable URL, and crawl access for the home page and the image. With that in place, you can:

• Give people a recognizable marker in search results, tabs and bookmarks, without relying on a promise that Google will show it.
• Catch a broken icon before a launch or campaign, when small presentation issues are most visible.
• Keep subdomains distinct, so a help center or store does not inherit the main brand's icon.
• Replace outdated or inappropriate imagery before Google swaps it for a default icon.

The result is not a ranking lift. It is a cleaner search appearance and one less loose end in a site review.

• Fast diagnosis. It reads the same link element Google reads and shows whether the address, type and size are usable.
• Clear format guidance. It tells you whether the file is a supported type and meets the minimum dimensions.
• Crawl checks in one place. Confirm that the home page and icon file are not blocked, a common reason an icon never appears.
• Subdomain coverage. Each hostname can have its own icon, and a check makes that separation visible.
• Better handoff. A short report gives designers and developers the same facts, which shortens the fix.

1. Enter the site address, using the exact hostname you want to review. A subdomain needs its own check.
2. Run the Traffsite favicon checker and read the link tag it finds. Confirm the rel value is icon, shortcut icon, apple-touch-icon or apple-touch-icon-precomposed.
3. Check the file's format, 1:1 aspect ratio and dimensions. Aim for more than 48x48 pixels, even though the minimum is 8x8.
4. Confirm Googlebot can crawl the home page and Googlebot-Image can crawl the icon file. A robots.txt block on either will stop the process.
5. Fix the file or tag, keep the URL stable, and then request indexing of the home page. Allow days to weeks for a recrawl.
6. If the icon still does not appear, compare the file Google can fetch with the one your browser shows. A CDN or cache layer may be serving an older version.

• Site owners: want the search icon to match the brand.
• Designers: need to confirm a logo works at a very small size.
• Developers: manage link tags, static assets and caching rules.
• SEO specialists: include search appearance in a technical review.
• Agencies: launch or rebrand sites and need a repeatable pre-launch check.

You do not need to read the HTML specification to act on the result. The report names the file, the tag and the obstacle, and the fix is usually a new export, a corrected path or a crawl rule.
