The trigger
Site has no favicon
The fix
Add a favicon. Browsers fetch /favicon.ico whether you ship one or not — without it, every page request logs a 404 and tab/bookmark UX is broken.
Code example
<!-- in <head> -->
<link rel="icon" type="image/svg+xml" href="/favicon.svg">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32.png">
<link rel="apple-touch-icon" href="/apple-touch-icon.png">Related patterns
