Add alt text to every image on your site

Adding alt text to every image on your site describes each image for visitors using screen readers and for search engines that cannot visually interpret images, closing both an accessibility gap and an SEO gap at once.

This is foundational, low-effort-per-item work with real accessibility and SEO value, and it is one of the most commonly incomplete basics even on otherwise well-built sites.

How to do it

1. 1
   Audit for missing alt text sitewide

   Check your CMS media library or page source for images with no alt attribute.
2. 2
   Write specific, descriptive alt text for each

   What the image actually shows and its purpose on the page, not a generic filename.
3. 3
   Use empty alt text for purely decorative images

   Tells screen readers to skip images with no real informational content, rather than reading a meaningless filename aloud.
4. 4
   Build this into your ongoing publishing process

   New images added going forward should get alt text at the time they are added, not left for a future cleanup pass.
