# What Is Image URL Checker? A Practical Guide to Broken Image Links

A broken image doesn't just look bad — on a product or article page it can be the single biggest trust signal working against you, since visitors read it as a site that isn't maintained.

Image URL Checker exists to solve one specific, recurring problem: broken image links is easy to get wrong by hand, tedious to check manually across a whole site, and quick to fix once you can actually see it clearly. That's the gap Image URL Checker fills.

In practice, this usually comes up in one of two situations — you're setting things up correctly from the start on a new page or site, or you're auditing something that already exists and trying to find what's silently broken. Both are worth doing regularly, not just once.

A few things worth keeping in mind:
- Check image URLs after any CDN migration or hosting change — this is the single most common cause of sitewide broken images.
- Use descriptive, keyword-relevant filenames and alt text — beyond accessibility, alt text is what Google Images actually indexes on.
- Serve images over HTTPS on an HTTPS page — mixed content warnings from HTTP images can block rendering in some browsers.

It's also worth knowing what commonly goes wrong here. Leaving `alt=""` on meaningful images purely out of habit — empty alt text should be reserved for genuinely decorative images only. And avoiding these is usually less about effort and more about knowing to check in the first place.

This connects to a few other things worth getting right at the same time — see Sitemap Generator and Keyword Density Checker for the related pieces of the same technical foundation.

If you want to check this on your own site right now, Image URL Checker runs directly in your browser, free, with no account required.
