6 Best WordPress Image Optimization Plugins to Speed up Your Site [2019]

Images are the first thing to optimize to improve your site’s speed.

Images are a big part of your website.

They help attract readers to your posts, and help make content more interactive. Image optimization is a technique used by many WordPress blogs around the web, and it’s essential to a successful website that ranks well in the search engines.

Why use Image Optimization on your WordPress site?

It can make your site’s loading time significantly shorter.

This is done by reducing the files size of images, by reducing the resolution to what is needed and by stripping metadata (information such as when the picture was taken, what device was used etc). 

Not only does it help your site load faster, but well optimized images can also help boost your Search Engine Optimization as your site speed increases. You can also use images to rank well through adding alt and title tags to your images. If these tags are filled with keywords relevant to your article, it will be easier to find on a search engine, as they pick out key words when search the web.  Google also factors in Page Load time as part of it’s ranking algorithm, so your website speed really does matter.

This can be made a lot easier with automation, through plugins.

Before even using these plugins, you should make sure that:

  1. Your images are only as big as they need to be. The file sizes of images on your webpage can greatly affect the loading speed of your page. For example, unnecessarily large images, with big resolutions will take up resources, and ultimately will slow down the loading speed of your page. If these images can be set to a lower resolution, or compressed to be a lower file size, then this will speed up your website. To do this, images can be compressed, so that unnecessary information is no longer included, such as capture date and type of camera used.
  2. Your images are given relevant names. This will boost your SEO. Images with relevant names will be more likely to appear in search engines, thus optimizing your post, and directing traffic to your blog. This can be done simply, by adding a keyword into the title of the image.
