How Search Engines Operate

Clifton Mccoy November 9, 2018

Search engines and the entire digital landscape are already huge parts of our everyday lives. Search engines have two primary functions—building and crawling an index, and offering users with a ranked website which they assume to be the most relevant ones.

1.Crawling and Indexing

You can regard the world wide web as a series of stops in a large city subway system.

Every stop is a distinct document—can be a web page or other files. It is the job of search engines to crawl the whole city, and look for stops throughout the process. To be able to do this, they need to utilize the best addresses and paths available. What are they? They are called links.

The website link structure binds all pages together.

Website links allow search engines’ robots, called spiders of crawlers, to reach out to billions of connected documents within the web.

Once search engines find the web pages, they figure out the code, and store chosen pieces huge databases. This will later on be recalled, when it is needed for a certain search query.

Every internet user is busy. These people demand instant results. This is the reason why search engines strive hard to provide important answers and details as quick as possible.

2.Offers Answers

Search engines are considered as answering machines. When a user performs online research, search engine goes through millions upon millions of documents. Then, it displays useful and relevant results to the query, and ranks the results according to website popularity. Therefore, we can say that it is popularity and relevance that influence the SEO process.

So, how do these search engines define popularity and relevance?

For search engines and web optimization expert, relevance is more than just than just looking for a page using the right words. Thousands of factors can influence relevance.

Search engines usually believe that popularity determines the value of a website. So far, this assumption remains to be true.

Remember, relevance and popularity are not determined manually. These search engines utilize different mathematical equations, also called algorithms, to get relevance, and arrange everything based on popularity and quality.

Algorithms are composed of various variables. We sometimes call them as “ranking factors.”
