How does Search Engine work? (SEO 1)

Search engines have two major functions 

      Crawling & building an index, 

and 

providing answers by calculating relevancy & serving results.

Imagine the Web as a network of stops in a big city subway system

Each stop is its own unique document (usually a web page, but sometimes a PDF, JPG or other file). The search engines need a way to “crawl” the entire city and find all the stops along the way, so they use the best path available – links.

The link structure of the web servers to bind the pages altogether.

Through links, search engines’ automated robots, called “crawlers,” or “spiders” can reach the many billions of interconnected documents. Once the engines find these pages, they next decipher the code from them and store selected pieces in massive hard drives, to be recalled later when needed for a search query. To accomplish the monumental task of holding billions of pages that can be accessed in a fraction of a second, the search engines have constructed datacenters all over the world.These monstrous storage facilities hold thousands of machines processing large quantities of information. After all, when a person performs a search at any of the major engines, they demand results instantaneously – even a 1 or 2 second delay can cause dissatisfaction, so the engines work hard to provide answers as fast as possible.

Search engines are answer machines. When a person looks for something online, it requires the search engines to scour their corpus of billions of documents and do two things – first, return only those results that are relevant or useful to the searcher’s query, and second, rank those results in order of perceived usefulness. It is both “relevance” and “importance” that the process of SEO is meant to influence.
To a search engine, relevance means more than simply finding a page with the right words. In the early days of the web, search engines didn’t go much further than this simplistic step, and their results suffered as a consequence. Thus, through evolution, smart engineers at the engines devised better ways to find valuable results that searchers would appreciate and enjoy. Today, 100s of factors influence relevance, many of which we’ll discuss throughout this guide.

How Do Search Engines Determine Importance?

Currently, the major engines typically interpret importance as popularity – the more popular a site, page or document, the more valuable the information contained therein must be. This assumption has proven fairly successful in practice, as the engines have continued to increase users’ satisfaction by using metrics that interpret popularity.
Popularity and relevance aren’t determined manually. Instead, the engines craft careful, mathematical equations – algorithms – to sort the wheat from the chaff and to then rank the wheat in order of tastiness (or however it is that farmers determine wheat’s value).
These algorithms are often comprised of hundreds of components. In the search marketing field, we often refer to them as “ranking factors” Moz crafted a resource specifically on this subject – Search Engine Ranking Factors.

Updates Chris Elliott, Elliott Abe, Michelle Rodriguez, symbolism, Michelle Rodriguez and symbolic and there are few jobs, just as television crappy as a member of cast for the first year on the Saturday Night Live. They are called "The players featured" but they are often featured in the exhibition closing credits, where they stand on stage and wave at the audience in the studio. And rarely get any screen time, and when they do it tends to be a spare bit or waitress in a bar or hit one of passers-by with no dialogue. Basically, the roles it is important that anyone in this cast can not be a real bother. When you do not get to strut their wares comedy, can be confusing. They are like a man no one knows the party gets too drunk and becomes the loudest person in the room. Even if they're really funny, it's hard not to be a little hurt them. "Only what the fuck are you?"
Abe Elliott joined Saturday Night Live last September to appear in the season 34th, although it was not provided with the official offer until November 15, when he played a pivotal role in the "girl carrying the board" in the formulation of Beyonce. Since then, they were sporadic moments of unforgettable Snell, most notably the wonderful and a little creepy impression of Angelina Jolie.
