TIP 11Ah the ALT tag. An essential part of that on-page quality score seo crow about lol :)

  • Keyword in the Title Tag – Check
  • Keyword in the Page Content – Check
  • Keyword in the meta description – Check
  • Keyword in the ALT Tag?

Bumfluff Alt Text Check!Not quite!

If you were checking off some quality score card and ensuring your keywords where in every flippin’ tag on your page you’ve probably told Google what to derank you for if you don’t have the link-power to back it up (and sometimes, even if you do).

Use ALT tags (attributes) for descriptive text that helps visitors – and keep them unique where possible, like you do with your titles and meta descriptions. Sure, throw your keyword in there if you want once or twice.

Don’t obsess. Don’t optimise your ALT tags just for Google – do it for humans, for accessibility and usability.

And remember – even if, like me most days, you can’t be bothered with ALT tags, at least put a blank one in so people with screen readers can enjoy your page.

Update 17/11/08 – Picked This Up At SERoundtable about Alt Tags:

JohnMu from Google: alt attribute should be used to describe the image. So if you have an image of a big blue pineapple chair you should use the alt tag that best describes it, which is alt=”big blue pineapple chair.” title attribute should be used when the image is a hyperlink to a specific page. The title attribute should contain information about what will happen when you click on the image. For example, if the image will get larger, it should read something like, title=”View a larger version of the big blue pineapple chair image.”

Barry continues with a quote:

As the Googlebot does not see the images directly, we generally concentrate on the information provided in the “alt” attribute. Feel free to supplement the “alt” attribute with “title” and other attributes if they provide value to your users!So for example, if you have an image of a puppy (these seem popular at the moment :-) ) playing with a ball, you could use something like “My puppy Betsy playing with a bowling ball” as the alt-attribute for the image. If you also have a link around the image, pointing a large version of the same photo, you could use “View this image in high-resolution” as the title attribute for the link.

There is also a Google blog post on using alt tags as well as a video by Matt Cutts, of Google.
