How to Optimize Speed of Your WordPress Website
Analyze your Site speed
Let us go step by step to increase your website speed:
Install W3 Total Cache
This WordPress plugin is the best WordPress caching plugin. This plugin
will save some html, css, JavaScript files to the browser of the user.
Next time when user will open the website, the browser will instantly
load the page using these static files. This can really increase the
speed of your site many times.
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.
Image optimization
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.
You can also specify the dimensions in the WordPress while uploading the image. You do not need any additional image for that.
JQuery with CDN
JQuery is the most used WordPress JavaScript library. These JavaScript
libraries are hosted on Google’s CDN. There is a plugin called “Use
Google Libraries”, which will help you to decrease latency, better cache
and manage parallelism with these JavaScript files.
