# How to Use Image URL Checker the Right Way (2026)

Getting broken image links right isn't complicated, but it does have a correct order of operations — skip a step and the rest of the work doesn't hold up as well.

Start here:
1. Check image URLs after any CDN migration or hosting change — this is the single most common cause of sitewide broken images.
2. Use descriptive, keyword-relevant filenames and alt text — beyond accessibility, alt text is what Google Images actually indexes on.
3. Serve images over HTTPS on an HTTPS page — mixed content warnings from HTTP images can block rendering in some browsers.
4. Compress and lazy-load below-the-fold images; broken links aside, oversized images are still one of the top page-speed issues on the web.

Once that's in place, the real value comes from doing it consistently rather than once. Image URL Checker is one of those tasks that pays off more from a regular check-in than from a single perfect pass.

A mistake worth calling out specifically: Not checking image URLs on paginated or filtered category pages, where broken thumbnails are easy to miss during a manual review. This is common enough that it's worth a deliberate check, not just an assumption that it isn't happening.

This pairs naturally with Sitemap Generator best practices — the two are frequently part of the same technical SEO pass, and fixing one without the other leaves an easy win on the table.

Image URL Checker does the mechanical part of this for you — the judgment calls above still matter, but the setup and checking becomes a couple of minutes' work instead of a spreadsheet.
