We strongly recommend optimizing your WordPress website to keep your website.

Pro-tips when selecting plugins
Before installing a plugin, view the plugin's details first by clicking More Details.
Here is where you can check the plugin's information.
Compatible with your WordPress version
Ensure to select a plugin that has been tested and is compatible with your WordPress version. You will want to make sure that it plays nicely with your core WordPress files.
Compatible PHP version
It is equally important to check if the plugin is supported by your hosting server's PHP version. Incompatibilities can cause serious errors, or the website may not load properly at all.
Select a plugin that is being maintained and updated by the plugin’s developer. An outdated plugin may not work or function correctly with your updated WordPress version or theme.
It is nice to see when a plugin is popular, as it’s a great indication that others have found it useful and successful. Keep in mind that you might happen upon a new plugin that has yet to be discovered by other users.
Look to see how many stars that plugin has been rated, along with how many people have rated it. Five stars with only 1 review are different than 4.5 stars and 633 reviews.
Check your existing plugins
Any plugins that are not vital to your WordPress should be deleted. Please remember that any time you add additional plugins, each of these plugins can increase your resource usage. We recommend no more than 3 to 5 active plugins, not including your caching plugin.
If you're having difficulty with your site that may be caused by a plugin, you can disable all of your plugins to return your site to a functional state. At that time, you may reactivate them one at a time and observe their impact on your site before activating the next plugin. This is also one way of optimizing your WordPress site.
HostGator has this helpful article which includes information on how to monitor your site's resource usage to determine if it is impacted:
In addition to checking this manually, the following plugins are known to be severely resource-intensive and could cause downtime, longer page load times, or larger process counts.
- Google Sitemap
- StatPress and other WordPress statistics software plugins
- WP Post Views
- WPRobot3 and other auto-poster plugins
- Some SEO plugins
- Some image galleries and media players are intensive, but this largely depends on how you use them.
- All related posts plugins such as WordPress Related Posts or YARPP
- All Backup plugins
The following plugins are recommended by HostGator as they provide features for WordPress that are in high demand, such as SEO functions, without harming your site:
There are a few plugins that HostGator strongly recommends that every WordPress user install. These plugins actively improve the efficiency and health of WordPress sites:
- Install WP Super Cache or W3 Total Cache
The installation of either of these plugins can be done from your WordPress Dashboard under Plugins. Follow the links below for information on how to set up these plugins:
- WP Super Cache (recommended)
- W3 Total Cache
- W3 Total Cache is a more advanced and feature-rich caching plugin. It is normally overkilling and can adversely affect performance if it isn't set up correctly. If advanced caching features such as Minify or CDN integration are needed, you should use this plugin.
- Install a Database Optimization plugin
Frequent updates and large databases can cause severe issues with CPU usage. The following plugin is highly rated for optimizing WordPress databases:
- Install Anti Spambot plugins
Unlike caching plugins, you can have multiple plugins that prevent spam bots from abusing your site with large quantities of spam and attack.
This plugin automatically filters and deletes spam posts on your blog, which can dramatically increase your resource usage as well as inconvenience you with Spam.
