Web design Essex OptimisedAs far as technology goes, caching has to be up there as one of the most beneficial. Essentially, it helps to speed up websites and that leads to improved SEO Scores and better user experiences, all of which can really make a difference. It can help to enhance conversions and profits should your website offer a product or service.

However, caching might seem like a mystery to many but it is in fact a very useful tool that is important for many reasons.

So, What does it mean?

If you scratch beneath the surface then caching is a complex and complicated thing. The inner workings of it are pretty precise but the underlying idea is one that is extremely simple.

Website speed mattersTo explain it better, if you are asked a question such as “what colour is the sky” then you will know that it is blue. You didn’t have to think about it or go looking for the answer because it is something that you have seen and talked about probably thousands of times in your life. You essentially recall it from memory without having to process it all. This is how caching works.

In general, websites can be viewed millions of times in a month. Normally, when a browser sends a request to receive a web page, the server has to carry out complex calculations. It picks up the latest information, generates the header and footer as well as other aspect of the site. However, in many instances, all of these calculations will present the same results. Therefore, caching helps servers to remember the result and so, it no longer has to deal with every request separately.

So, if a website owner has caching enabled, the first time someone visits it, the page will be displayed to them in the normal way. Therefore, a request is made, the server processes it and then the webpage is turned into a HTML file and then presented to the visitor. However, as caching is turned on, the server will store this HTML file within the Random Access Memory (RAM). As a result, the next time someone visits the site, the server doesn’t have to do so much processeing and so, it sends the HTML file to the browser.


If caching is enabled, then a websites can load up in a split second. So, caching is definitely worth it making browser and serve caching a worthwhile choice. It is important to make the browsing experience as quick as possible for people when they want to view your site. So, implementing caching is always worthwhile because you don’t just speed up your site, you also improve its performance, helping it to cope with any sudden spikes in traffic.

Caching is both effective and efficient. In a world where visitors want things quickly, your website has to respond to every request. Therefore, this simple yet effective option can help to drive your website and help it to keep visitors intrigued.
