No favicon
23.6%
of the 3,044 free scans considered in the last 30 days raised this finding. That is 717 scans across 717 distinct sites. 95% interval 20.6% to 26.8%.
What it means
A missing favicon shows as a blank tab and a blank bookmark icon, small, but the first thing a returning visitor recognizes.
How to fix it
Add a favicon at /favicon.ico plus <link rel="icon"> in the head. It is the mark shown in tabs, bookmarks and search results.
How to check it yourself
Load the page and look at the browser tab icon, then open example.com/favicon.ico directly. A blank tab or a failed request means none exists.
What fixed looks like
The browser tab shows a favicon, and example.com/favicon.ico loads an icon instead of failing.
How we measured this
Go Voltic scans a site and records which findings it raises. The share above is over every free four-page scan in the last 30 days that loaded at least one page, which is 3,044 scans. Deep scans of paid reports and of the research sweep read a site at a different depth and are a separate population, never in this denominator. It is not a survey and it is not an estimate: it is a count of what our own scanner found. Sites are counted once each in the distinct-sites figure, so a site scanned twice does not weigh double there.
The interval is a 95% Wilson interval. A share printed without its sample size reads as certainty and is indistinguishable from a guess, so both are always shown. Figures on this page were computed on 2026-09-08.
The same share sits beside every other finding on the benchmarks page, which also carries the whole table as CSV and JSON and says how to cite it.

The free scan reads four pages and reports every finding it raises, including this one. It takes about ten seconds and asks for nothing but the address.
