What the checker looks for
- <link rel="icon"> tags in the HTML, including SVG and PNG icons.
- /favicon.ico in the site root, which many browsers and crawlers request automatically.
- Apple touch icon — a 180×180 PNG for iPhone and iPad home screens.
- Web app manifest icons — 192×192 and 512×512 PNGs needed to install the site as an app.
Every icon is downloaded to confirm it returns HTTP 200, with its type and file size.
Favicons in Google Search
Google shows your favicon next to search results on mobile and desktop. To qualify, the icon must be crawlable, square, at least 48×48 pixels and declared with a link tag on the home page.
Frequently asked questions
Why is my favicon not showing in Google?
Google needs to recrawl your home page, and the icon must be at least 48×48 px, square and not blocked by robots.txt. Updates can take several weeks.
Which favicon sizes do I need?
A 32×32 or SVG icon for browsers, a 180×180 Apple touch icon and 192×192 and 512×512 icons in a web manifest cover almost every device.
Do I still need favicon.ico?
It is still useful as a fallback because many tools request /favicon.ico automatically.
