Use when checking whether a site has a correctly configured favicon, auditing `<link rel='icon'>` tags in the `<head>`, or setting up favicon infrastructure for a new project.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Add a favicon to every page

Google displays favicons next to search results on mobile devices, making your brand immediately recognisable in the SERP. A missing or inaccessible favicon prevents Google from showing it, reducing visual brand presence in search.

## Quick Reference

- Provide a `<link rel="icon">` pointing to a favicon file; Google uses it to identify your site in search results
- Serve the favicon via HTTPS, ensure it is publicly accessible (not blocked by robots.txt), and at least 48×48px for Google's use
- Include both an ICO fallback and SVG/PNG versions for broad browser and device compatibility

## Check

In the page `<head>`, look for `<link rel="icon">` or `<link rel="shortcut icon">` elements. Verify: (1) The href points to an accessible URL (returns 200, not blocked by robots.txt). (2) The file is at least 48×48px (for Google Search use). (3) A PNG or SVG version is provided alongside the ICO fallback. (4) The favicon is accessible over HTTPS.

## Fix

1. Create favicon files:
   - `favicon.ico` (16×16 and 32×32, ICO format) — legacy browser fallback
   - `favicon.svg` (scalable, modern browsers)
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add thedaviddias/front-end-checklist/favicon@sha256:5604c2cefafd4c2e

The line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
