Earlier this week I talked about 5 reasons to SEO images on your website. In this post I’ll talk about how to SEO 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.

Image or a picture on your website is content that’s being indexed by Google. Moreover, Google has a separate search engine for images. These are 5 reasons to use and SEO image files for search engines like Google.

Image files contribute to your on-page SEO

Any given page on your website will have a number of content types showing. For example, it’s going to be text, video, links, images. Each of those on-page SEO elements play as a team to identify the relevance of your page for Google. That is why I strongly recommend that each of your pages has an SEO optimized image.

Now that we’ve gone through all 5 on-page SEO contenders and their on-page SEO factors, let’s do a summary of findings and things to keep in mind when thinking about on-page SEO for your website.
