Caching is perhaps one of the most critical and essential tasks you would need to perform if you want to optimize your site. Of course, you will find that website owners do not pay attention to this mode of website optimization.
Designed as an essential element of making your site run faster, caching is something you should never ignore. So what exactly is caching and why it is so important? We will explore the concept of caching and its functionality in finer detail in this post.
What is WordPress Caching?
Caching, as most of us are aware of, is a process where a frequently used data is stored temporarily as a cache. If you do not use cache, your site can face a lot of speed and server related issues.
When a visitor requests information from your site, the browser sends a request to your web server or web host. The data so required will include images, CSS files, PHP files, scripts and other elements that make up the page. The web server compiles this information and sends it to the browser. Your browser will then present the content in the human-readable format.
Now that WordPress has its content updated dynamically, each time your visitor comes to your page, the whole process is needed to be repeated. This can considerably reduce your site load times. Ultimately, the user may get bored and move away to some other site or page.
What is Caching?
Caching involves creating local storage of your website content and serving it to the user. The cache files are stored as static pages, and they are faster to load. This ultimately helps in reducing the load time of the website.
The dynamically generated web pages from WordPress sites are saved on the physical memory or RAM and served to everyone who visits the page and it results in saving a lot of computational time. That’s what we call WordPress Caching.
However, imagine a situation when a new post is published, or a new comment comes up on the site … if the same old information is shared, it will be considered as outdated information and thus be invalid in more ways than one. The WordPress core files and the caching plugins (if you are using them, and you should use them) know exactly when to rebuild the cache. That’s done through what is called Cache Purging.
Cache Purging refers to removing the old cached data and reaching the data. After deleting the old cache files, the new ones are created or regenerated. It ensures that while the load times are maintained within the best possible levels, the user is not served the invalid or irrelevant data.
Why is Caching so Important?
Page load time is one of the most important elements in any computational process. Everyone loves fast loading sites including Google and other search engines. If you want to rank at top position in the search results, you should understand clearly that the key factors that ensure a higher SERP also includes response time and speed of a website.
And caching plays a significant role in ensuring a faster performance of a website. It assumes even more significance when it comes to WordPress as it is a dynamic platform and employs PHP code in association with the MySQL database. If you have been able to configure your caching protocols properly, you will end up turning your site faster.
You can speed up your website by employing three major options – using powerful servers, using a CDN or content delivery network and opting for WordPress caching. The first two options can be expensive sometimes and it will also be dependent upon the number of visitors you have. Thus WordPress caching is one of the most important aspects of handling your website.
