In João Craveiro’s blog, I’ve just found a link to a very informative article: High Accessibility Is Effective Search Engine Optimization.
It makes a lot of sense, if you think about it a little. What’s accessibility? It’s making sure your blog or site is readable even to people with some kind of disability - sight, hearing, etc.. How do you do that? Consider blind people - they’ll be using a browser capable of reading text out loud. Note the “text” part. Their browser won’t interpret Javascript or anything like that, won’t show Flash animations, or read text inside images - it can, however, read the “alt” tags in those.
Have you ever tried a text browser, such as Lynx? Try browsing to your site with it. Can you still read the content? Navigate around the site? Use most or all of the options? Post new content, if the site allows it?
Because, if you can’t, neither can a blind person.
Or what about a cell phone browser? Opera 8.0 in my Nokia 6630 is almost like a “normal” browser, but what about an older version, like Opera 6.2, or even worse, the browser that came with the phone. How’s your site in it? A complete mess? Or still usable?
And now think about search engine crawlers. What do they do? They “read” the text, and follow links. Nothing more. Hmm, isn’t that a lot like what a browser for blind people does? Or a text browser?
I won’t give a list of tips here, because I’ve already mentioned a lot of them in my Blogging Tips series, and also because the linked article itself has a list of such tips. But now you know that I wasn’t just being pedantic when I said that <img> tags must have the alt=”description” part.
