How Search Engines Work

In the field of search marketing, search engines are the most important thing that needs to be understood. How search engines work is one of them. In this article, seo Toronto will discuss how search engines work. Search engines have 2 main functions: crawling & indexing, and providing answers through the calculation of relevance to then given to the user.

Imagine the World Wide Web as a collection of stores in the largest shopping center. Each stop has its own unique document. Search engines need a plan to “crawl” the entire shopping center and find each store and they need a way to find it, through the path it goes through, in this case, is the “link”.

The link structure of the website aims to unify all the pages of a website. Through links, search engine robots called “crawlers” or “spiders” can reach billions of connected documents. Once the engine finds those pages, the next thing is to decode the “code” of the website and save a certain part of it into the hard drive that will later be needed for the search query. To be able to run a fast search process, search engine companies have built data centers in many places in the world. This facility uses thousands of machines that process large information. This is, of course, to ensure search results appear to users as quickly as possible. Just imagine, this machine can process the search results you do in just seconds.

A search engine is an answering machine. The search process that someone does online makes the search engines search for answers between billions of documents and do 2 things: first, provide answers that are only relevant to the search, then determine the ranking of the search results based on its usefulness to the searcher. The two factors of “relevance” and “importance” are processes that need to be influenced by SEO.

For a search engine, relevance is not just finding the page with the right words. Initially, this is indeed a simple process undertaken by search engines and causes various things like spamming which ultimately give irrelevant search results. Hence through various changes, the programmers find a better way to provide the best results and useful to the seeker. Now, hundreds of factors influence the relevance and search results of search engines.
