Image descriptions should help users understand the image’s role. Search optimisation should preserve that purpose rather than turn descriptions into keyword lists.
Name and place images meaningfully
Use a short descriptive filename before publication when practical. Place the image near the explanation it supports. A product photograph and an installation photograph answer different questions, so use captions or nearby text to provide context. Keep image URLs stable once they are in use.
Write alt text for the purpose
Describe informative content that is relevant to the page. For a functional image link, communicate the action or destination. Decorative images may need empty alt text. Avoid repeating nearby prose unnecessarily, guessing unseen specifications or inserting every service location into the description.
Check delivery and accessibility
Verify that the image loads, remains legible at its displayed size and has suitable dimensions. Review alt text in the rendered page, including CMS-generated galleries. Optimise file weight without erasing important labels. Image SEO works best when the asset is useful and the surrounding page is clear.
