Search engines have two main functions: scanning data and build a table of contents, and provides searchers a list of websites that rank that is most relevant.
Imagine a global network of networks (the world wide web) as a network of stops on the subway system of a large city.
Each stop is a special document (usually a web page, but sometimes a PDF, JPG, or other file types). Search engines need a way to scan the entire city and find out all the stops on the way, so it uses the best path available – links.
Scanning and indexing
scanning and indexing billions of documents, web pages, files, news, video, and media on the global information network.
Provides answers to questions from users, most often through the list of related sites that it receives and ranked according to relevance.
Path structure of a website serving for connecting all the pages together.
The link enables automatic robot of the search engine, called “crawlers” or “spiders”, access to billions of documents linked together on the web.
When the search engines to find these pages, it will decode from this page and store the selected page in the database, the document will be recovered when the search query. To complete the work stored billions of pages that can be approached in a heartbeat, the company’s search engine built around the world.
The physical basis of this huge store keeping thousands handling equipment large volumes of information quickly. When a person performs a search in any major search engine, they are keen to have instant results, even delayed 1 to 2 seconds can make them unhappy, so the search engines always try to provide answers as quickly as possible.
The search engine can serve as the answering machine. When a person performing an online search, search engine glance system billions of its data and does two things: first, it returns only the corresponding results or helpful with questions to find Search, secondly, it ranked these results based on popularity of websites providing information. SEO is the process affects both the relevance and popularity.
The search engines determine relevance and popularity in any way?
For a search engine, relevance means more pages to find the right words. In the early days of the web, the search engines do not go beyond this simple step, and the results have limited value. Over the years, engineers have researched better ways to answer the question in accordance with the search. Today, hundreds of factors influence relevance, and we will discuss the most important issues of the problems in this guide.
The search engine is often said that the website, page, or document more and more popular, the information it contains even more important. This statement has been proved to be relatively successful in pleasing the user with search results.
Prevalence and associated not determined by manually. Instead, the tools use the mathematical formula (algorithm) to remove the husks of wheat ready (relevance), and then ranked according to the quality of wheat (popularity). These algorithms include hundreds of variables. Search marketing in the field, we see it as “ranking factors”. Moz has built separate document for this topic: Factor ranking search engines.
So how do we succeed?
Or, “the search marketing success somehow”
These complex algorithms of the search engines can look through cryptic. In essence, the search engine itself provides an inside look at us how to achieve better results and increase traffic. What it gives us to optimize and how to do best are described below:
