How Do Search Engines Work? 4 Important Functions!

Crawling => Indexing => Rendering => Ranking

There is a very important communication platform between your target audience and your website: search engines. They enable users to find your website by searching for specific keywords, thus enabling the flow of visitors to you.

But how exactly does this process, which we always know “the last step” of, works very well? How exactly does your website is crawled, indexed, rendered, and ranked on certain keywords?

If you want to have information about SEO, if you want to strengthen the rankings of your website with strong SEO studies, you must first understand the working logic of Search Engines.

Crawling

Digital software that provides web crawling, defined as robots, spiders, or bots, create a virtual experience by traveling between the links on your site (they actually jump from one page to another via links that bind them).
Through this experience, they will examine your website. Bots that navigate from one link on your website to another can learn about the user experience offered by a specific web page.

Indexing

The job of storing data on a web page is called indexing. A bot comes to your website and crawls it. Then the contents, links, and much more on this page are cataloged, which means they are indexed by the search engine. As you can imagine, this will require a very powerful computing resource.

Rendering

All content prepared to be published in the digital world on a web page is stored as HTML, CSS, and Javascript files. The browser’s task is to read and interpret these files by analyzing the relevant languages (the code languages). When these codes are converted into a web page, the browser interprets the files in front of the user. HTML or Javascript files with high load require a high loading process. In the modern era, it is recommended to save many links as HTML files.

Ranking

A search engine aims to show the users the result most relevant to the keyword they are searching for, thereby increasing the user experience. To do this, they rank the web pages in terms of the content they offer, their speed within the site, and other features that affect the user experience. This ranking shows how much more visible web pages are in related keywords than their competitors and directly affects visitor traffic. Results that offer the most relevant and successful performance are shown higher in search engines.
