noimageindex blocking image visibility
noimageindex stops the images on a page being indexed. For any page that earns visibility through visuals, recipes, products or how-to imagery, that is a real loss.
What it is
Images on the page won’t be indexed.
Why it matters
Removes image-search and multi-format AI surfaces for the page’s images.
How to fix it
Remove unless images must be hidden.
How to find it on your site
- Search the robots directives for noimageindex.
- Confirm the page relies on image search or rich visual results.
- Check it is not set site-wide by a template.
- Remove it where image visibility matters.
Cross-reference to ranking and citation factors
Image indexing is its own discovery surface. Blocking it removes a route to traffic and to visual elements in AI answers.
