The prompt for Claude Code

Copy and paste this into your Claude Code chat exactly as-is.

Run Claude Code in the project root and make these exact changes, scanning the whole codebase first:

Add a favicon

1. Add a favicon.ico file to /public/.
2. Also add <link rel="icon" href="/favicon.ico"> in <head>.

Why this matters

Google SERP on mobile shows a favicon next to each result. No favicon = a generic globe icon, which looks untrustworthy next to branded competitors.

Browsers show the favicon in the tab. Without one, users see a blank sheet, and bookmarks have no visual identifier — harder to re-find your site.

How to use this prompt in Claude Code

1. Open your Claude Code project.
2. Copy the prompt above with the copy button.
3. Paste into the Claude Code chat and send.
4. Review the diff, accept the changes, redeploy.
5. Verify the fix using the checklist below.

Common mistakes to avoid

error_outlineShipping only a 16×16 favicon — looks blurry on Retina displays and in Google SERP.
error_outlineUsing a photo as favicon — does not read at small sizes.
error_outlineForgetting the Apple touch icon (180×180) — iOS home-screen icon falls back to a scaled-down version.

How to verify the fix worked

check_circleCheck `favicon.ico` at the root returns 200.
check_circleGoogle SERP (site:yoursite.com on mobile) shows your favicon, not the globe.
check_circleBookmark the page and check the bookmark icon is correct.

Frequently asked questions

ICO or PNG?expand_more

Both. Keep a classic `favicon.ico` (16+32+48) at the root for legacy, plus PNGs for modern browsers and Apple touch.

When does Google show favicons?expand_more

Mobile SERP, since 2019. Desktop shows them in some contexts. Either way, have one.
