Image SEO

One of the most frequently asked questions lately has a lot to do with image SEO: how do I optimise my images for the search engines? (Without misleading the users I’d like to add.)

As SEOs, we work with words. We need words to communicate with both the SE and the users. So you need words to optimise your images for the search engines. As simple as that. The search engines do index images and recognize them as important elements of your website, but they cannot “read” your images or “see” them, unless you tell them what to see. It’s up to you to have your images properly indexed. It’s up to your words!

File names are very important. Instead of a simple logo.jpg you should consider using your brand name. For example, for our logo we would use: SEO-logo.jpg (or gif, or any other supported format). SEO has two meanings in this particular case: search engines optimisation and Search Engine Oracle. No matter how you look at it, it’s a keyword rich file name and it makes sense for the users as well. Do I need to tell you that software generated file names are a no-no? Note that I wrote SEO-logo and not seologo. Search engines are not always able to separate the words correctly.

Don’t ignore the alt text attribute. That’s the right place to describe your image for people with disabilities (blind people) or for users that browse the Web with text based browsers. The alt text attribute helps the search engines as well to better categorize your images. Captions and labels should be used ethically: no spam. You won’t get away with it!
