Seen from the Internet side, the operation of Google and other search engines seems very simple. You type your query into the search box, and in less time than it takes to say it, your results are displayed. Here is the question I asked Laurent : “Do you know how Google works to find and rank Dominican Republic Email List billions of web pages and then show me the results when I type a query?” In “cooking”, this instant result is produced by a complex set of processes that help identify the most relevant data when looking for your favorite recipe, product, information or simply to get your question answered.

The details of the process are technically very complex. However, knowing the non-technical basics of how they work is helpful in understanding SEO methods. Contents [ display ] A titanic job Google: How Does It Work? Explore, Index & Sort In 2017, Google announced that it knew more than 130 trillion web pages. Today, he no longer communicates on this figure. Anyway, that’s huge, 1,000 times 130 billion! Today it may be even more. Especially since there are many pages that Google does not take into account. For example, Facebook pages are not listed by Google, let alone the Dark Web . Considering all this amount of pages, how do you stand out from the crowd and stand out from the competition?


How Search Engines “see” A Web Page

This is what digital marketing experts call natural referencing. And to be a champion, you might as well know how search engines work. In order to make the results of a query as relevant as possible to Internet users, Google and other search engines have put in place a well-oiled process to identify the best web pages for the requested query. In summary, as Google explains , the functioning of a search engine is made up of 3 mechanisms: Explore the web , that is, browse links one by one to discover the most important pages on the web, Index the pages , i.e. record certain information from the identified pages, Classify the results , that is to say understand the subject of a page and classify it according to the requests that the Internet user requests.


Explore the web Google: How does it work? Explore the web Search engines have “robot” programs (also called “spider” or “crawler”); These bots “crawl” the web to find the pages that exist and identify the best pages to remember for a given query. When a robot comes across a web page, it scans it for links to other pages. By following these links, robots browse the billions of interconnected pages. It’s a bit like pulling a piece of the yarn from a ball of yarn. Thus, like Internet users, robots discover new pages on the Web every day.


Personal Thoughts On How A Search Engine Works

Each link found is then put in a queue that the robot will explore later. Browsing the billions of pages of the web every day is surely impossible to do. Even with its thousands of bots constantly running on thousands of computers around the world, I imagine it takes Google days, if not weeks, to get around them. So, I imagine that it sorts according to the authority of the domain name or an equivalent criterion, but also surely according to the rate of update of its content. My advice : To facilitate the task of robots, it is strongly recommended to: Declare your website to search engines with a sitemaps.xml file, And for the more expert among you, to configure your robots.txt file, to indicate to the robots which pages to take or not to take into account during their exploration.

It is also essential to: Declare your redirects properly to avoid having broken links, Maximize your internal linkage so as not to have orphan pages , that is to say not linked with at least one other page of its website. And to identify broken links on your website, use the free online Broken Link Checker tool. Then once the broken links are known, on WordPress, make your redirects with the free “redirection” extension. For experts, submit your new posts to Google directly in the Google Search Console with its URL inspection tool. 2. Index the pages Google: How Does It Work?
