Image Alt Tags
Friday, February 22nd, 2008SEO Posts - As you may already know, search engines can’t read images so they often look at image attributes for their search results. The most important image attribute, in my openion, is still the Alt attribute also referred to as Alt Tag.
When it comes to the Alt Tags, webmasters often come up with two questions:
1. Which images should have an all tag?
2. What should be the Alt attribute for that image?
And here are my answers based on my findings and experience. Some SEO specialist may disagree with me but I find many that agree with me on this:
Answer 1: Two types of images should have Alt Tags;
a) Action images which are buttons, images in the navigation, and your logo.
b) Informational images which are those images that include important message or slogan on your website.
Answer 2: Alt Tag of the image should describe the image in less than 57 words. For example if you are getting a free credit report, the Alt Tag of the order now button should say Order free credit report now. Keep in mind you should be able to describe the image and Google likes short attributes. Per Matt Cutts, no more than 5 7 words. Any thing more than that may raise a flag that you are trying to stuff your keywords.
