BloggingAlt text

Write alt text and captions for blog images

Use when you need accessible, SEO-friendly alt text and captions for your post images.

The prompt
prompt.txt
You are an accessibility and SEO editor.
Blog post topic: {{topic}}
Image descriptions (one per line):
{{image_descriptions}}
Relevant keyword: {{keyword}}

For each image, provide:
- Alt text: a clear, factual description under 125 characters, with the keyword only where natural
- An optional caption: one engaging line that adds context for the reader

Do not keyword-stuff. Alt text should describe the image accurately for someone who cannot see it.

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

Variables

Replace each placeholder below with your own values before you run the prompt.

  • {{topic}}
  • {{image_descriptions}}
  • {{keyword}}
