If you’re running a website on WordPress, speed is of the essence. A slow website can lead to a poor user experience, which can cause visitors to leave and hurt your search engine rankings. Fortunately, there are many ways to speed up your WordPress website, one of which is using a WordPress hosting service with built-in caching. In this article, we’ll explain what caching is, how it works, and why it’s important for your website’s speed. We’ll also take a look at some of the best WordPress hosting services that offer built-in caching.
What is caching?
Caching is the process of storing frequently accessed data in temporary storage locations, such as RAM or solid-state drives (SSDs). When a user requests data from a website, the server can retrieve the data from the cache instead of fetching it from the database or file system. This can significantly reduce the time it takes to load a page and improve the user experience.
How does caching work?
When a user requests a web page, the server generates the page by executing PHP code and querying the database to fetch the necessary data. This process can be time-consuming, especially if the database is large or the code is complex. With caching, the server can store a copy of the generated page in memory or on disk. When another user requests the same page, the server can serve the cached copy instead of regenerating the page from scratch. This saves time and reduces server load.
Why is caching important for website speed?
Caching can drastically reduce the time it takes to load a web page. According to Google, the average mobile landing page takes 22 seconds to load. However, 53% of mobile site visitors abandon a site that takes longer than three seconds to load. By using caching, you can reduce the load time of your website and improve user experience. Additionally, faster websites tend to rank higher in search engine results pages (SERPs), which can drive more traffic to your site.
Types of caching
There are several types of caching that WordPress hosting services can use to speed up your website:
- Page caching: This type of caching stores entire web pages in memory or on disk. When a user requests a page, the server can serve the cached copy instead of generating the page from scratch.
- Object caching: Object caching stores individual objects, such as database queries or PHP objects, in memory or on disk. When a page is generated, the server can retrieve the necessary objects from the cache instead of querying the database or executing PHP code.
- Opcode caching: Opcode caching stores compiled PHP code in memory so that it can be reused across multiple requests. This can eliminate the need to re-execute the same code every time a page is loaded.
