Favicon missing/broken
A missing or broken favicon leaves a generic icon in tabs, bookmarks and even some search results, a small polish and brand gap. A correct favicon set fixes it.
What it is
No valid favicon.
Why it matters
Misses the SERP favicon; minor.
How to fix it
Provide a valid favicon.
How to find it on your site
- Check whether the favicon loads in the browser tab and is not 404ing.
- Confirm the link rel icon references resolve.
- Provide a proper favicon set for different contexts.
- Re-check across browsers.
Cross-reference to ranking and citation factors
A working favicon is a small brand and polish signal, and can appear beside results. Its absence looks unfinished.
Impact
Low. Inferred.
