# Favicon Monitoring — the Small Icon With a Big Job

Your favicon is your brand in every tab and bookmark, and it quietly vanishes after rebuilds. WatchFor tells you when it goes missing, turns into an HTML page or shrinks to almost nothing.

## Simple checks that guard your brand

Presence, content type and size in one tiny monitor.

### Presence verification

Looks for /favicon.ico first, then the icons your HTML link tags name, then apple-touch-icon.png and favicon.png. Favicon Missing is on by default and fires when none of them loads.

### Content-type validation

The Wrong Content-Type rule checks the file is served as an image, catching the classic failure where the icon URL returns an HTML error page instead.

### Size tracking

The icon's size in bytes is recorded on every check, and the Favicon Too Small rule alerts below 100 bytes by default, catching empty or placeholder files.

### Content hash

Each check stores a SHA-256 hash of the icon and the URL it was found at, so you can tell when the file itself changed.

### Multi-region checks

Checks run from the regions you choose (your plan sets how many), so you see the icon your CDN actually serves, not just the one in your office.

### Confirmed alerts

Failures are confirmed from several locations before an incident opens, so you only hear about real problems.

### History you can audit

Whether the icon was found, its size and where it came from, on every check: handy after messy deploys.

## A closer look

Alert when the icon goes missing, turns into an HTML page or shrinks.

Each check records where the icon was found and its content hash.

## Why watch a favicon?

Nobody budgets time for the favicon, which is exactly why it breaks silently. Build pipelines rename asset paths, CDN migrations drop odd files, and browsers cache the old icon just long enough that your team never notices. Meanwhile new visitors see a blank tab and the page still returns 200, so uptime checks miss it. A tiny automated check removes the whole problem class.

## How favicon monitoring works

Set it once — hear about it only when it breaks.

1

### Add your site

Point WatchFor at your site; the monitor finds the favicon at /favicon.ico, in your HTML link tags or at the usual fallback paths.

2

### We fetch and validate it

On every check the icon is fetched and validated — presence, content type and size — with a preview in your dashboard.

3

### Problems get flagged

A missing icon, a wrong content type or a file that's too small triggers an alert, confirmed from several locations first.

4

### You fix it before users notice

The incident shows when it started, which usually points straight at the deploy that did it.

## Who needs favicon monitoring

Small check, outsized embarrassment prevented.

### Brand-conscious product teams

A blank or default icon in hundreds of tabs is a quiet credibility leak. Get told soon after it happens instead of noticing weeks later.

### Teams with busy deploy pipelines

Asset hashing, path rewrites and framework migrations are the classic favicon killers. Automated checks catch the regression soon after it ships.

### Agencies managing many sites

One monitor per client site turns 'the icon disappeared' tickets into alerts you already fixed.

### Teams mid-rebrand

Shipping a new icon? The new size and content hash in each check confirm the new file reached production in the regions you check.
