So it’s not surprising that Google continues to emphasize the speed of the site in its search algorithm. The faster the page, the better your search rankings and the more organic traffic you can attract.

What is Cache?

Simply put, caching is basically a simple solution to a complex problem: Pages in WordPress are generated dynamically, when a user enters the website and accesses, for example, an article, a request to the server is made so that this page is processed and delivered, then the PHP programming language kicks in and performs several queries in the database to build the requested page and return it to the user.

As the number of visits to your site increases, this ends up overloading the server and reducing the response time of the page for the user. This is where the cache comes into play, as most pages do not need to have necessarily dynamic content, it creates a static page file, and whenever the user requests it, it delivers that page already created, which dramatically reduces processing and response time.

The Cache normally works with an expiration time, for example, your home page can have an expiration time of 24 hours, when the Cache sneezes, a new updated version of the page is generated and served to its users.

Working with caching in WordPress can be complicated, as many users use ready-made themes, optimization can become a complicated and boring task, but don’t worry, most plug-ins can do an excellent optimization job with little effort.

Why You Use Cache

  • Speeds up the site for users : We have already covered this, but it is good to mention it again, as it is the main advantage.
  • Improves the overall user experience : As the site loads faster for users, they are now more likely to browse and may decrease the bounce rate for your site, many people do not want to wait 10 seconds to view a page.
  • Your server uses less resources : It puts less pressure on your server, reducing the processing and memory needed to withstand the stress of many users, and can even reduce hosting costs.
  • Increase in search engine optimization : You show Google and other search engines that your site is worth indexing in a higher ranking, as this is a very important metric for your ranking.
