Working of Search Engines

When you hunt for something in Google (either some other search engine), an algorithm operates in real-time to carry you what that search engine recognizes the “best” result.

Precisely, Google scans its contents of “hundreds of billions” of pages to find a set of results that will adequately answer your search.

How does Google decide the “best” result?

Even though Google doesn’t get the internal functioning of its algorithm public, based on filed patents plus statements from Google, we know that websites, including web pages, are ranked based on:


In Case you search for “chocolate chip cookie recipes,” you don’t need to see web pages about car wheels.

That’s why Google scans first-and-foremost for pages that are precisely related to your keyword.

However, Google doesn’t merely rank “the most appropriate pages at the top.” It is because there are thousands (rather even millions) of relevant pages for each search term.

For instance, the keyword “cookie recipes” brings up 345 million results in Google:

So to fix the results in an order that works the beneficial to the top, they rely on three other parts of their algorithm:


Authority is like it sounds: it’s Google’s way of deciding if the content is reliable and trustworthy.

The puzzle is: how does Google understand if a page is valid?

They gaze at the number of other pages that connect to that page:
In stock, the more links a page has, the higher it will rank:
(In case, Google’s ability to contain authority via links is what divides it from search engines, like Yahoo, that occurred before it).


Content can be appropriate and authoritative. However, if it’s not useful, Google won’t want to place that content at the top of the search outcomes.

Google has openly said that there’s a distinction separating “higher quality content” also “useful” content.

For instance, let’s say that you hunt for “Paleo Diet”.
The initial result you click on (“Result A”) has written by the world’s leading expert on Paleo. Also, because the page has so much variety of content on it, lots of people have connected to it.
Nevertheless, the content is entirely unorganized. Also, it’s full of jargon that most people don’t realize.
Distinguish that with another result (“Result B”).
It has signed by someone comparatively new to the Paleo Diet. And their website doesn’t have nearly as many links pointing to it.

Still, their content has designed into distinct sections. Furthermore, it’s written in a way that anyone can follow:
Well, that page is operating to rank profoundly on the “usefulness scale.” Moreover, though Result B doesn’t have as complete trust or authorization as Result A, it will still function well in Google.
(In fact, it may even rank HIGHER than Result A)
Google estimates usefulness primarily based on “User Experience Signals.”
In different words: how users communicate with the search results. If Google recognizes that people like a relevant search result, it will get a vital ranking boost:
