In case you missed it, a short while ago we posted a video about how to use ALT attributes for images. I’ll include the video here, but I’ll also use this opportunity to remind everyone that you really should subscribe to the Official Google Webmaster Blog (Atom link for feedreaders). Here’s the video:
In the comments, you’ll note that Philipp Lenssen corrects me about something: “IMG” is a tag, but “ALT” and “TITLE” are attributes of the IMG tag. So referring to an “ALT tag” is a bit sloppy and incorrect.
Luckily, the webmaster central folks were kind enough to clarify the original post. John Mueller also made the original post even more valuable by talking about ALT and TITLE and how those attributes are slightly different. John is one of the newer voices in webmaster/SEO communication (okay, he’s been a voice for quite a while, but only joined Google a few months ago); I’m really glad that he’s joined Google. For example, you might have missed his incredibly useful meta tag reference guide that he posted not long ago. Yet another reason why you should be subscribing to the Official Google Webmaster Blog (Atom link for feedreaders). At this point, the official webmaster blog is doing Google SEO-related posts faster than I can.
