Have you ever wondered how Google actually works? How, in the space of a fraction of a second, its search engine manages to analyze, sort and index Wallis and Futuna Islands Email List of pages based on user requests, and repeat this feat billions of times a day? Although the giant of the Silicon Valley is not the type to reveal its secrets, it lifts the veil somewhat on the mystery thanks to this magnificent interactive infographic in three parts which explains in a simple and playful way the way with which its engine of research proceeds.

Find the full infographic here . NB: While reading, do not forget to move your cursor over the various images on the infographic, some are clickable and contain rather interesting additional information … Part 1. Data indexing by Google The first of three parts of this infographic explains how Google scans the World Wide Web (which currently contains over 30 trillion individual pages!) For content and lists it in its virtual index. This part teaches us that: Google’s crawlers scan the web from page to page using hyperlinks as highways ; The pages visited are then sorted according to their content as well as other factors; They will then be stored in a giant index (which weighs over 100 million gigabytes!)

Search engine algorithms

Google engineers are constantly creating and improving (500 to 600 times per year) their search algorithms to better adapt to technological developments (as well as to hackers) to provide users with the best results in response to a submission of request. It is these programs and formulas that will decide which pages deserve the best positions in the Google results. Here’s how :

When a request is introduced into its search engine, Google processes it by analyzing up to 200 different factors in order to better understand the requested search and better target the results;
Then he interrogates his index and pulls out the pages he deems most relevant ; And it finally ranks the results according to various criteria (quality of the page and of the site, “freshness” of the content, relevance of the translation, number of inbound links, etc.) on your results page … all at high speed average 1/8 th of a second! Awesome, isn’t it?

Deal with spam according to Google

It is really interesting that the 3 th and final part of this infographic is fully dedicated to spam-related practices, evidence that Google cares more about this issue, especially since the release of its latest Penguin update ( see in this regard our article on the subject ). Spam techniques (or ” black hat SEO “) aim to manipulate Google’s algorithm by placing sites at the top of the results through fraudulent practices, such as the incessant repetition of keywords, the purchase of links or duplicate content. For Google, fighting spam is essential to ensure relevant results. How is it treated?

Although the methodology is written into the algorithms and therefore automated , it also happens that the Google anti-spam team deals with certain contentious cases manually ; When spam is detected, the site owner is always notified so that they have an opportunity to fix the problem and before irreversible actions are taken. Google’s goal has always been the same: to be able to offer users the information they are looking for as simply as possible. This is the reason why its search engine is thinking more and more like a human being, favoring useful content that brings real added value to poor and artificially optimized content. In short, if you want to be in the small paper of Google, there is only one solution: regularly produce fresh and quality content!
