Alt-text for images inside the content (builders)

What it is

Google reads the alt attribute of the <img> tags that are actually in your content, not just the alt stored in the Media Library. AISA therefore writes alt-text in two places: the attachment meta, and the inline <img class="wp-image-N"> tags inside the post body. Updating only the library alt would not change images already placed in the content, so AISA rewrites the tag's alt directly.

Where to find it

It happens automatically during image alt generation (1-Click SEO with images, or the Images action in Bulk SEO) and when you regenerate a product's images. The featured image gets its attachment alt; inline images get their tag alt rewritten.

Requirements & tier

Same providers as Vision alt-text. Works in BYO-key and Cloud. Inline matching relies on the standard WordPress wp-image-N class on the image tag.

How to use

  1. Generate image alt-text via 1-Click SEO or the Bulk Images tab.
  2. AISA sets the featured image alt on the attachment.
  3. For each <img class="wp-image-N"> in the body, it replaces or inserts the alt attribute.
  4. Existing alt values are swapped; missing ones are inserted right after <img.
  5. Re-check the rendered page — the inline images now carry descriptive alt-text.

Questions people ask

  • Why edit the tag and not just the library? Because changing only the library alt does not touch images already inserted in the content.
  • How are inline images identified? By the WordPress wp-image-N class that ties the tag to an attachment.
  • Does it work with page builders? Where the builder stores standard <img> markup with the WP class, yes.
  • Is each alt a separate operation? Yes — one alt equals one operation.
  • Does it touch images without that class? It targets the WP-class tags; unrelated decorative markup is left alone.

Troubleshooting

If an inline image keeps an empty alt, check that the tag carries the wp-image-N class (some builders strip it). For purely builder-managed widget images, use the relevant builder/Content Fix path instead.
