As all know WordPress is a well-coded platform for implementing websites. Most of the Bloggers use Wordpress as their blogging platform. So optimization plays an important role to speed up your websites.
Today, most of the Telecom Provider started providing 4G internet so people using 4G networks surfs the internet with high speed and they are concern about speed in the web, but if your website is not optimized to achieve the speed and if it is loading slow then it will affect your website. People will only wait a few seconds for website response if your website response is slow and does not loads fast they will move to another similar website.
So here I will show you how to optimize your WordPress website to gain maximum speed.
1. Select Best Web Hosting
Selecting the right hosting is the first and most important choice for optimizing WordPress websites.
If you are buying a hosting you should check the location of their servers in which hosting company will host your website, Storage Space, Server Uptime, Bandwidth Speed, Allowed Server Resources and Storage Type.
Location of server matters because, if you are hosting the website which will gain high traffic from a particular country like INDIA then you should select the hosting such that hosting servers are located in the same country as low latency also provides better speed and performance to websites.
I think that you all are familiar with normal HDD storage and high-speed SSD storage. If your website are hosted on SSD storage servers, then definitely you will get high read/write speed on your website compare to HDD.
We Recommend using galaxywebcloud.com as a Hosting Provider. galaxywebcloud.com provides SSD-Based Storage and LiteSpeed Optimized web hosting which is easier to scale your website on time.
2. Install Caching Plugin
The second important and effective way to improve the site’s load is a caching plugin. If you are using web hosting from galaxywebcloud.com or any other host which provides LiteSpeed web server, then you can install LiteSpeed caching plugin in WordPress. This will give you the best optimization with LiteSpeed web server and LiteSpeed caching.
Cache plugin ensures that the site does not load directly from your server files it must load from saved cache from the visitor’s browser. So it cuts the resources required to load the website and provides faster loading of websites.
There is one small issue you can aware of before caching your site. Caching displays the saved cached version of your website to your site visitors. Therefore, it may show outdated information if your website has dynamic elements.
You can also use similar plugins for caching (ex: W3 Cache, WP Super Cache, W3 Total Cache, etc)
3. Use Content Delivery Network (CDN) to deliver your website
Content Delivery Network is designed to optimize the security, performance, and reliability of the Web Server. CDN is easy to setup. When visitors request some websites which are using CDN then the request will go to the nearest CDN server and that server will respond to the visitor (see below figure).
CDN refers to network of proxy server which are spreaded all over the world. Every server of CDN contains a copy of your website. which is used to deliver your website, due to this your primary server will have less load to handle the request, and thus it will improve the performance while serving the website.
CDN is also used to protect websites from attacks like Distributed Denial of Service (DDoS). CDN blocks all unnecessary and bad requests generated by attackers.
We Personally recommend using Cloudflare CDN, Fastest Global Content Delivery Network.
4. Image Compression/Optimization
Most of the websites drain their performance due to images. Images are great to make websites look and feel amazing. Images are important to websites like portfolios, galleries, and stores. High-quality Images require more Storage Space and Bandwidth. High-quality images have a negative effect on loading time and bandwidth usage, which decreases the user experience.
Image Compression/Optimization is a process to decrease the size of images without decreasing the quality of the image (lossless compression). For image compression, you can use websites like compressor.io, tinypng.com, compressimage.toolur.com, etc.
After compressing the Images with lossless compression the size of the image will be decreased to 60-70% than the original size, so that will take less storage space and bandwidth usage. After Compression, you can use a caching plugin like LiteSpeed cache to optimize the image.
5. Delete Post Revisions and Clean up Media Library
What are Post Revisions?
If you update or edit some old posts, then old posts will be saved as revisions act as backup. You must remove Post Revisions by using Plugins like Revision Control.
As your site grows your media library also grows accordingly. Media Library consists of hundreds of images, documents, and other files. It is necessary to clean up unrequired files, images, documents from Media Library. One can use a plugin like Media Cleaner to clean up the Media Library.
6. Perform Routine Maintenance of Themes and Plugins
One should always update WordPress and Plugins to their latest versions. New updates always come with security updates and bug fixes. Regular updates keep your website secure and optimized. 
Older versions of plugins and themes are generally more vulnerable to attacks. Attackers may find backdoors from an older version of plugins.
You should also disable, and delete the plugins that are not in use. The low-quality plugin also affects the speed of the website. You should only use High-quality themes and plugins.
7. WordPress Database Optimizing
Always clean up your WordPress Database. You can do it manually, but if you don’t have proper knowledge of database clean up then it may take your website down. 
The simple way to clean your WordPress database is to install WP-DBManager plugin.
These plugins are capable of deleting all your spam comments, trashed posts, auto-saved drafts, post revisions.
Before performing the Database Clean up you should always take a backup of your website. Because Database is a heart of WordPress websites if something goes wrong then you cannot revert back if you do not have a backup of your website.
