Image SEO tips

Image SEO fundamentals

Images contribute to page experience (size, format, lazy loading) and can rank in Google Images. Descriptive file names, accurate alt text, proper dimensions and modern formats (WebP/AVIF) improve both accessibility and discoverability.

Alt text

Describe the image content and function; include a keyword only when natural.

File names

Use descriptive, hyphenated names: red-running-shoes.jpg instead of IMG_1234.jpg.

Performance

Compress, serve next-gen formats, set width/height and lazy-load below-the-fold images.

How to use this tool

  1. Paste an image URL or the page that contains the images.
  2. Optionally provide existing alt text for review.
  3. Click Optimize Images to receive actionable recommendations (demo).
  4. Copy or download the tips and apply them in your CMS or code.

Best practices

  • Never leave alt empty on informative images; use empty alt for pure decoration.
  • Keep file size as small as possible without visible quality loss.
  • Use responsive images (srcset) for different screen sizes.
  • Add structured data (ImageObject) when images are primary content.

Frequently asked questions

Is alt text a ranking factor?
It supports accessibility and image search relevance. It is not a major ranking lever for regular web results but remains important.
Should every image have a unique file name?
Yes when the images are distinct. Reused stock photos can share names, but descriptive names still help organization and image search.
