Caching is a process of hierarchical storage of data so that once a user clicks on the content, it loads much faster the next time.
Doing this stores the data it receives from the data center to its server. Whenever the user visits that page or URL, it shows that stored data. If the content changes then it will run once again and save the new data.
Caching is everywhere if we only focus. Since it stores the information it receives for the first time. Our brain also catches information our eye receives and processes thoughts.
Caching is not just confined to a website. There are many other types of caching as well such as
- Data Caching
- Application Caching/Output Caching
- Distributed Caching
In simple words, caching saves a copy of a web page. The benefit of caching is that the next time you visit that page or website or let’s just say you reload the web page, it loads much faster.
You must have gotten the idea of caching and its benefits by now.
Technically, the details of caching can be pretty much complex, but the general idea is very simple. Let’s just say I ask you about a mathematical problem. Your brain will take some time to process the information for the result.
Now, if I ask you the same question again, you will instantly answer me because your brain had already gone through the process and knows the answer already.
The same is the case with caching. In the IT field, caching is an important and fundamental concept. Since caching makes things faster, so many software developers consider it essential.
Caching has a lot of importance in SEO. As Google considers page speed as an essential ranking factor, a website needs to load much faster. Because if it doesn’t, then website rankings drop to a great extent.
Developers make most websites through WordPress. The reason people choose WordPress is that it is SEO-friendly.
