Earlier this week I talked about 5 reasons to SEO images on your website. In this post I’ll talk about how to ensure you have SEO friendly images on your website or blog. There’s a number of important image properties that should be taken into account: size, name, alts, titles and captions. Let’s start from the top.
Optimize the size of your image
Optimizing the size of your images is not directly related to SEO. However, very large images can slow your page down. And by now we know that Google looks at page load speed as a ranking factor. In other words, slow pages rank worse. The idea is to balance between the image quality (user orientation) and its load speed. In my experience images of 100kb should give you a good balance.
