The use of images, along with other media elements, has always been a way to engage your visitors and hold their attention. Many websites have too much text that visitors will never read. Why not integrate more contextual images into your content? Not to mention they are more important since the rise of blended or universal search. Remember blended search is the method search engines use to combine different types of listings in the search results. Things like images, video, news articles, local listings, etc.
So not only do images help engage your visitors but you can also achieve high rankings within the search engines for images and pictures you have on your site. So how do you optimize images for SEO?
