When you run a large website with loads of users, caching can be a major tool for reducing page load times. When you use a WordPress caching feature, you may notice that changes made to your WordPress site are not shown automatically to users at the front end of the web. This is because your posts are cached and are still displaying the old version. To resolve the issue you need to clear the cache on your WordPress site with the help of either “W3 Total Cache” or “WP Super Cache”
Why Is Caching Important In WordPress?
Caching for WordPress is critical for large websites with a lot of visitors to ensure quick load times and overall better visitor experience. It’s easy to use and easy to configure, with caching plugins readily available for handling the task
WordPress caching is critical to ensuring your site’s smooth performance and giving users an excellent experience on the site. Because WordPress dynamically generates HTML pages, caching ensures that frequently accessed site pages-such as the home page-are stored in fast RAM so they load much faster. Caching frees the WordPress processor and, as a consequence, increases page load speeds for all web sites–even those not cached.
Caching is a blessing, if you have a smaller hosting plan Caching reduces server load and server memory, allowing you to choose a lighter hosting package while still performing on a larger server.
Google prioritizes websites with higher speed, the speed, and responsiveness of your web is one of the key ranking factors on Google’s search engine results pages, This rewards sites that respond quicker and launch sooner by offering them a page-ranked boost.
What Is Cache And Why Do We Need it?
Although modern hard drives are very fast on your web server, they are much slower than the RAM. Caching actually saves commonly visited sites and articles in RAM, and WordPress first looks for them in RAM – no need for database queries. Caching decreases server demand and improves the overall performance of the platform.
To speed up web browsing, web browsers are programmed to access and store web pages locally on your computer’s hard drive in a “cache” region. A web cache (also known as browser cache) includes archives of everything you viewed or downloaded while surfing the internet. So if you access the same website for a second time, you will notice a higher loading speed, since you’re accessing the file from the cache locally instead of downloading it all over again.
