Before delving into what caching is and how it can improve a website ranking, it is crucial to understand how SEO works. Search Engine Optimization or SEO, is the method of improving organic traffic to a particular website by making it rank higher in the search engines for relevant keywords. Of the many factors that determine the SEO and consequently, the search engine ranking, page load speed has become an important factor. Google has declared that page speed among its top determinants for its search engine algorithm as it directly affects user experience.
If you are a person who has been using the internet, the chances are that you must have heard of caching. It is a popular idea that caching reduces the load time of a webpage. This type of caching is called browser caching, and it usually affects the performance of a page on the user front. However, caching on the server can drastically improve page load speed and give a boost in website rankings of the search engine.
What is Caching and How Does it Work?
Caching can be defined as the static HTML version of the contents of a webpage. Whenever a user requests a particular webpage from their browser, it has to go through an entire process through the server, which fetches and sends the information back to the browser. Caching eliminates this time-consuming process by serving the static version of the website, which loads much faster. Usually, the server stores the HTML version of the page within its RAM. It reduces page loading time while also enhancing user experience at the same time. Better user experience and lightning page load speed can boost your website ranking in the search engine.
One common misconception which has crept around caching is that for dynamic websites whose content changes frequently, caching can be a hindrance. However, the caching mechanism allows configuration which resets every time it notices some changes.
Types of caching:
Broadly, there are two types of caching.
- Browser caching: It stores the static file on the browser, thus reducing the number of requests it sends to the server.
- Server caching: This caches the contents on the server itself, thereby eliminating the need to go through the entire process every time a user request those contents.
Benefits of caching:
- Speed and performance: It optimises the performance of your website by improving page load time.
- Reduced load on the server: It avoids over-burdening on the server thus saving memory and I/O operations.
- SEO favourable: As discussed before, page load speed and performance are vital for search engine rankings.
- Better user-experience: Surveys have confirmed a user does not wait for more than three seconds for a website to load. A website with better page speed provides a better user experience.
