Optimizing for Google Images, the image search engine at http://images.google.com, involves two things. First, make sure the image names have good keywords in them, separated by hyphens. Not too long though. Do keyword research to identify the best keywords to use. Second, make the content around the image and the alt tag for the image have good keywords in them. Before you begin optimizing, an important question to ask yourself is: Am I sure I’ll actually attract high-value customers through Google Images? It could be that you’ll end up getting plenty of traffic, but the conversion rate could be quite poor because they aren’t shopping for your product but instead just for an image of it.
