Image SEO Checklist Before Publishing
Image SEO is not a single trick. It is a set of publishing habits that make images easier to load, understand and reuse across search and sharing surfaces.
Use meaningful filenames
A filename should give a basic clue about the image. Use simple words separated by hyphens and avoid long random export names.
A useful filename does not need to repeat every keyword on the page.
Add relevant alt text
Alt text should explain the image in context. It supports accessibility and can help clarify the purpose of the image.
Do not invent visual details or use alt text as a list of search terms.
Prepare preview images
Open Graph and article preview images often use wide ratios such as 1200 x 630. A mismatched image may crop poorly when shared.
Prepare a dedicated preview image for important articles, products and campaign pages.
Keep images fast
Large image files can slow pages and make content feel less polished. Compress images and serve responsive sizes when possible.
