How to Optimize Image to Improve SEO for Better Rankings

When most people think of search engine optimization (SEO), they tend to associate it with optimizing text-based content using keywords. However, websites nowadays no longer rely solely on text, and odds are yours uses its fair share of images too. As such, it is important that you optimize your image SEO as well if you want to rank well on search engines.

Although you may be used to dealing with SEO in general, image SEO is a slightly different beast. It relies on the same principles as regular SEO, but because search engines can’t ‘see’ images (at least not correctly) they rely on other means to translate those images and determine their relevance. Because of that, a good part of image SEO focuses on making it as easy as possible for search engines to determine what the content of a picture actually is.

Don’t worry if you’re unsure how that can be accomplished, as it isn’t nearly as complicated as it sounds. In fact, all you need to do is take care of a few different aspects:

Use descriptive file names for images

How to Optimize Image SEO for Better Rankings - Point 1Because search engines can’t ‘see’ images, they often rely on file names to determine what the content of a picture is. That is why you should steer clear of generic file names (e.g. IMG2334.jpg) and instead use descriptive ones such as ‘half-eaten-apple-illustration.jpg’. The more descriptive the file names, the better, and if you want to go the extra mile, you can even carry out research into what type of keywords are used to search for the content of the image and optimize it accordingly.

Make use of alt tags
