Analyze your Site speed
Let us go step by step to increase your website speed:
Install W3 Total Cache
Once the plugin is installed you need to turn on page cache, object cache, database cache and minify under the general settings. Under the browser cache enable cache control header, an entity tag, set expires header. And this will automatically increase the speed of your page.
Fix Gravatar issues
Gravatar is to show your avatar in the comments. This is free of cost, preinstalled WordPress service. If you turn the Gravatar off, your webpage will look quite boring or plain.
There is a plugin Nix Gravatar cache which fixes all the gravatar related issues automatically. It works very smooth and requires no additional efforts.
Large size images on your site can slow down your website to load. It is always recommended to use medium size images and optimized as well. With WordPress site, you do not have to worry about this. There are some plugins which you can install which will automatically optimize the image you will upload. Plugins like WP smushit and EWWW Image optimizer are two very great plugins to optimize the image on your site.
