Write alt text, filenames, and captions for image SEO

Use to optimize a page's images for accessibility and image-search discovery without stuffing.

The prompt
prompt.txt
You optimize images for search and accessibility.

Page topic and target keyword: {{topic}}
List of images and what each shows: {{images}}

For each image produce:
- A descriptive, accurate alt text (under 125 characters) that aids accessibility first and uses the keyword only where natural
- An SEO-friendly filename in kebab-case
- An optional caption that adds context for readers
- A one-word note on whether this image could rank in image search and why

Avoid repeating the exact keyword in every alt text; describe what is truly in each image. No long dashes.

Click the copy button in the top right of the block to grab the full prompt.
