Do you use search engines? I bet you do. And do you know exactly why do you use them? This question is a little bit more difficult. We’re so used to them that we don’t even consider any different ways of browsing the Internet. In fact, without search engines many of us couldn’t even take a single step in the Internet, not to mention looking for important information, for instance while working. Frankly speaking, there are innumerable purposes we use search engines for. Yet only few of us are aware how they really work.
Every time when you type anything into a search engine, you get comprehensive results. But these results, as you might have noticed, are not fixed. In other words, they may vary depending on when you type them, what kind of device do you use and where do you use your device. That’s because search engines use plenty of complicated, sophisticated algorithms in order to specify and determine positions of particular websites in the ranking. Now they do, and how did id work long time ago?
The first steps
Back then, when Google was starting, they’ve come up with a simple yet very useful idea that revolutionized the Internet. It was truly simple and consisted in indexing pages and “ranking” them depending on their content. The result of such a calculation was a number from range between 0 and 10, where 0 was the worst mark, whereas 10 was virtually impossible to achieve and denoted the best website online. This algorithm was called pagerank algorithm tutorial
What happened later?
As you can probably predict or maybe you’re noticed for yourself, the idea developed significantly since then. “Page rank” is still used by Google and websites still have their “page rank” mark. However, today it’s rather a part of history than a truly useful idea.
