Image inside link missing alt text — the fix
A link contains an image as its only content, but the image has no alt text. This means the link has no accessible text, making it completely opaque to screen reader users.
Where this fits: accessibility in SEO
Accessibility overlaps heavily with SEO because both depend on machine-readable structure: alt text, heading hierarchy, labels, contrast. Screen readers and search crawlers consume the same signals. Accessible sites rank better not by special treatment but because the same fixes — descriptive alt attributes, proper headings, real link text — are exactly what search engines parse for meaning. It is also, in a growing number of jurisdictions, the law.
Why image inside link missing alt text hurts your rankings
When an image is the sole content of a link, the image's alt text serves as the link's accessible name. Without it, screen readers announce just 'link, image' with no context about the destination. This is both a WCAG 2.1 Level A violation and an SEO issue, as search engines receive no anchor text signal.
This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it.
How to fix it
Add alt text to the image that describes the link destination, not the image appearance. The alt text should function as the link text would.
<!-- Before -->
<a href="/"><img src="logo.png" /></a>
<!-- After -->
<a href="/"><img src="logo.png" alt="Company Name - Home" /></a>Accessibility best practices
- Give every informative image an alt attribute that describes its content; decorative images get alt="".
- Maintain heading hierarchy — never skip levels for styling reasons.
- Make link text meaningful out of context; screen readers list links in isolation.
- Keep text contrast at WCAG AA (4.5:1) minimum.
- Make everything keyboard-operable with a visible focus state.
