Questions, answered
Will it add the alt text directly to my WordPress images?
Never without your approval. It drafts suggestions in a Google Doc for review - only after your team ticks off each one should anyone apply them in WordPress.
How does it write the alt-text suggestions?
It uses the image filename, the post title, the surrounding heading, and the page's target keyword to write a descriptive, specific alt text. You can edit any suggestion before applying it.
What about images that already have alt text - will it overwrite them?
No. It only includes images where the alt attribute is completely empty or missing. Existing alt text is left untouched.
