Looking to improve the speed of your WordPress site? Using a cache plugin can speed up loading, creating a better experience for your users.
Statistically, nearly half of your website's target audience expects your website to load in less than three seconds. So it's not surprising that Google continues to emphasize site speed in its search algorithm. The higher your page speed, 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: WordPress pages are dynamically generated, when a user enters a website and accesses, for example, an article, a request to the server is made for that page to be processed and delivered , then the programming language PHP takes action and performs several database queries to build the requested page and returns it to the user.
As the amount of hits on your website increases, this ends up overloading the server and reducing the response time of the page for the user. That's where the cache comes into play, as most pages don't need to have necessarily dynamic content, it creates a static file of the page, and whenever the user requests it, it delivers that page already created, which drastically reduces processing and response time. The Cache normally works with an expiration time, for example, your homepage can have an expiration time of 24 hours, when the Cache expires, a new updated version of the page is generated and served to its users.
Working with caching in WordPress can be tricky, as many users use ready-made themes, optimization can become a complicated and boring task, but don't worry, most plugins manage to do an excellent job of optimization with little effort.
Why You Use Cache
- Speeds up the website for users : We've already covered this, but it's good to mention it again as it's the main advantage.
- Improves overall user experience : As the site loads faster for users, they are now more likely to browse, which can lower the bounce rate for your site, many people don't want to wait 10 seconds to view a page.
- Your server uses less resources : Puts less pressure on your server, reducing the processing and memory needed to withstand the stride 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 for a higher ranking, as this is a very important metric for your ranking.
