When it comes to your WordPress site, one seemingly small thing can make or break traffic — speed.
Your WordPress site should load in three seconds or less. Slow loading means visitors will leave your site, abandoning any purchases they planned to make.
Luckily you can use WordPress performance plugins to make sure your site operates quickly, and loading speed doesn’t cause you to lose visitors.
Why Use WordPress Performance Plugins?
WordPress performance plugins make your site run and load more quickly. But that’s not all they do. They focus on key features that make your site perform better and faster.
Here are some of the areas in which WordPress performance plugins help optimize your site:
- Cache. A cache for WordPress is commonly accessed data that are temporarily stored to speed up processing. A computer can access this information quickly while retrieving any new information related to the site. Caching is the most common way to get your website to load faster and generally perform better.
- WordPress HeartBeat API. WordPress’s built-in server polling Application Programming Interface allows applications to talk to each other quickly. It allows for almost real-time updates.
- Reducing or Disabling Ajax. Ajax updates part of a web page without reloading the entire page. It can be helpful, but it also can slow down your Central Processing Unit, making it necessary to reduce or disable Ajax usage.
- Deferring Scripts. To defer scripts means you load your CSS or JavaScript files last, making your site accessible to visitors more quickly.
- CDNs. A Content Delivery Network distributes the work of delivering content to your web browser, making it more efficient by increasing the number of sources, their closeness, and caching.
- Lazy Loading. Lazy loading loads the parts of the website visitors are viewing first. Lazy loading means avoiding loading the whole page at once, which may take a long time.
- Minification. Reduces website load time by eliminating unnecessary content in HTML, JavaScript, and CSS files.
- Concatenation. Combining files to reduce the number of requests on your site.
Remember, when installing plugins, only install what your site really needs and what you’ll update regularly. Old, inactive plugins will slow down your site, defeating the purpose.
