Images missing alt text
image_alt_missingShort answer
One or more <img> elements on the page have no alt attribute. For people using a screen reader the image is invisible; for Google, alt text is the main signal about what an image shows and whether it belongs in image results. Write a short description for meaningful images (alt="Glimana dashboard showing the SEO score") and use alt="" for purely decorative ones.
Why it matters
Google's image SEO guidance calls alt text the most important attribute for understanding an image, and it is also what appears if the image fails to load. Accessibility law in many markets requires it. Missing alt is almost always a content-entry habit, so the fix is partly process: make alt a required field.
How Glimana detects it
The rule fires when the page has at least one image with no alt attribute at all; the evidence shows the count and the total images on the page. An empty alt="" is treated as a deliberate "decorative" marker and is not reported.
How to fix it
- Find the affected pages in Glimana. Open Issues › Images missing alt text. Every affected page is a row; open one to see the evidence Glimana recorded for it (the measured value, the offending element or the target URL). The same list sits on the task card under Tasks, and the page's own detail view under Pages shows its full signals.

Apply the fix on your platform.
Set the Alternative text field in the Media Library (it is used wherever the image is inserted). For theme images (logo, hero), the alt comes from the customizer or the block's settings.
Product images: Add alt text under each image in the product editor. Theme images: the alt field in the section settings.
Make
altrequired in the image model; outputalt=""for decorative images in templates. -
Publish and clear caches. Save and publish, then make sure the crawler will see the new version: WordPress — clear the page cache in your cache plugin and purge the CDN; Shopify — theme and content changes go live on save, but purge any CDN in front of the store; custom code — deploy and purge the edge cache. Check in a private window or with
curl -s https://your-domain/page | grep -i '<title\|canonical\|robots'that the live HTML has changed; Glimana reads what the server sends, not what your browser has cached. - Verify in Glimana. Open the task under Tasks and click Mark as done. The affected pages are queued for a verification crawl within a few hours, and the task closes when every image on the affected pages has an
altattribute. If the check still fails, the task returns to New with a note; when it passes, the task is listed under Resolved technical issues on Impact reports. To check sooner, use Re-crawl affected pages on the issue.
How the fix is verified
Re-crawl; the task closes when every image on the affected pages has an alt attribute.
