PageRank basics
- The concept: An algorithm created by Google's founders to measure the importance of a web page
- The principle: The more links you receive from "important" sites, the greater the authority of your page
- Analogy: It's a recommendation system. One link = one vote of confidence
- The challenge: A high PageRank greatly facilitates your ascent to the first page
In the world of SEOif there's one term that has changed everything, it's PageRank. Invented by Larry Page and Sergey Brin (the founders of Google), this system has transformed the web from a simple directory into a veritable digital meritocracy.
For a manager, understanding the PageRankis to understand how Google decides who is the market leader. Think of it as a score of popularity and trust: it's not the site that shouts the loudest that wins, but the one that is most recommended by others.
How does this "confidence rating" work?
PageRank is based on a simple idea: every link to your site is a vote. But at Google, not all votes are equal:
- Link to a small blog: A pat on the back
- Link to an institutional site : A prestigious recommendation that massively boosts your authority
The higher the PageRank of the sites that vote for you, the more "power" they transmit to you (often referred to as "Link Juice").
Why is it vital for your business?
Although Google now uses hundreds of criteria, the PageRank principle remains fundamental:
