Search engines like Google index images (record and catalogue the image in their databases) like they index text. Having images on your website that are fully optimized for search engines can improve your site’s listing in SERPs (search engine result pages), giving your site a shot at being on the coveted page 1 or 2 of Google, for example.
For visitors to your website, articles with images can evoke emotion making the articles more memorable, and/or they can be very instructive if they’re part of a tutorial or showcasing a product, service, idea, etc.
Try to include at least one image for each article that you post, and make sure that you have permission to use the image on your site by the person who created the image, if the person isn’t you. Online, Fotolia offers quality royalty free images that you can purchase, or you can search for free images to use in the “public domain” – simply search online for “public domain images” and you’ll find many options.
1. Before you upload the image to your site, rename it with relevant keywords that you researched.
imagestips.jpg is an example of what an image for this article could be named.
2. Also before you upload it to your site, resize the image if it’s large so it won’t increase your website’s loading time.
3. After you upload the image to your site, include the keywords that you used to name the image in the “alt text”.
This is the only element of your image description that will be visible to the search engine robots that will crawl and index your website.
