This is no hidden secret that Google gives preference to those pages which opens fast on browser. Site load speed depends on many factors and image size is one of them. If size of image is too much then your blog’s page load speed is also low which directly impacts your blog’s search engine result.
To solve this problem, there is a WordPress plugin known as Optimus which automatically compresses images of your blog to 50% without decreasing its quality. The main feature of this plugin is that it doesn’t need any effort in reducing the image size. It does everything automatically. All you need to do is install this plugin on your WordPress blog and that’s it.
Once installed, when you load any image on your WordPress bog, it sends that image into its own server and then processes it and send it back to WordPress blog. All this process takes place in very minimum amount of time.
