Alt Text Best Practices for SEO
Alt text best practices for SEO start with accessibility: describe the image for people who cannot see it. Search engines also use alt text as a clue to image context when it is written honestly.
Stuffing alt attributes with repeated keywords harms trust and reads poorly with screen readers. Describe what matters.
How to write alt text
- Be specific and concise
- Include the text in the image if that text is important
- Skip ‘image of’ fluff unless needed for clarity
- Use empty alt for purely decorative spacers when appropriate
SEO without spam
If the image shows a red running shoe on a trail, say that. If it is your storefront, name the brand and scene. Natural phrases beat awkward keyword piles for image SEO.
Linked images
When an image is the link, alt text should describe the destination purpose, not only pixels.
Editorial pass
Add alt review to content QA. Missing alts accumulate quietly on busy beginner sites.
Write alt text for humans first. SEO clarity follows when descriptions are true.
Put it into practice
Audit ten images on your top pages. Write accurate alt text for any that are blank or stuffed with keywords. Skip purely decorative images with empty alts if appropriate.
Write the change, the date, and what you expect to see in search or on the page. Beginners who keep a short SEO notebook learn faster than beginners who only react when rankings drop. One deliberate fix beats five random tweaks.
If the result is unclear after a week, do not scrap the whole site plan. Adjust the single variable you changed, or give the page more time while you improve a different URL. Steady SEO learning compounds when you refuse to thrash. Share the note with a teammate when you have one so the next change stays deliberate too.
- One SEO change, one week, one written expectation
- Check the page on a phone before you call it done
- Prefer clear evidence over hunches when you review results
- Capture a screenshot of titles or reports when you can
