Cache Memory – What Is It?
Close
Cache, also known as cache memory, is a broad term. It can refer to CPU, HDD, file system, or a web browser. The last one is the most important for marketing specialists, and web developers – dealing with browser cache is their bread and butter. But in fact, cache memory is a companion of every digital user – no matter if you’re currently catching up on morning news, doing research for a master’s thesis or watching a Pay-Per-View boxing event.
Web browser cache – cache memory definition
The cache memory in the browser is responsible for storing various website elements – images, JavaScript files, etc. Thanks to cache, after re-entering a given page, the browser does not have to load the entire content from scratch, and can refer to files saved in the memory. It significantly speeds up the whole process of web browsing, especially with websites that are visited regularly.
However, web browser cache can sometimes be a little tricky. Let’s imagine such a situation: you make changes to the website, and after refreshing, you still see the previous version. Usually, the magic key combination ctrl + F5 is much of help – it clears the cache for a given page.
The server cache is a separate issue – if the cache is refreshed, e.g. every 24 hours, changes in the content may be visible only after clearing the server cache – and until then the CMS will display the previous version.

Search engines cache
It is worth noting that you can visit cached pages from Google and other engines such as Bing. After entering cache:http: //verseoads.com in the address bar, you can see the current copy of the page saved in the Google cache – in this case, made a few days ago. Of course, you can enter any address after the cache: operator.
In Bing search results, just click the arrow to the right of the website address – after entering “cached” we can see a copy saved by the Bing engine.
Food for thought…
The cache of Google and other engines can be useful, for example, in journalism or during certain disputes (especially regarding e-commerce and online offers) to prove and document that the website has been changed.
From the perspective of an SEO specialist, the understanding of the caching frequency of the page (i.e. the fact that it is actually visited by search engine crawlers) is very important. The more often the bot indexes a given site, the better – in theory – for the position in the search results. Frequent indexing means that the crawler considers the site to be frequently updated and therefore worthy of interest.
