Images are a very important part of any website because they can attract more users. However, unnecessarily large file sizes can impact your site negatively by increasing the loading time of your site.

Images can send traffic to your site through the image search option on Google. All you need to do is to optimize your images with proper alt text and title tags.

Many new bloggers use extra-large images without understanding the proper file size required by the particular theme they use. It is important to understand your WordPress theme and the image sizes it needs.

You can use WordPress plugins to optimize the featured images of your site for increased traffic and faster loading times.
