Accessibility Information & Tips

Search Engine Optimization (SEO)

  • Using the "alt" attribute for images is not just good for accessibility, it's good for search engines too. Use the "alt" attribute to describe images but use relevant keywords and search terms in the description when appropriate, but don't overdo it by cramming in too many keywords. Consider using/adding graphic images, photos, or illustrations on important keyword-targeted pages with the important keywords used in the alt text.
  • Following accessibility standards may improve search engine rankings. Use "alt", "title", and table "summary" attributes whenever relevant and possible. Use keywords and search terms in them but keep them accurate. Using CSE HTML Validator's optional accessibility checking can help.
  • Image searches can be a significant source of visitors and traffic. Therefore, try to use keywords when naming images, and separate keywords with hyphens (not underscores).
