The bizarre way search engine operates

Search Engine
The search engine is the only place you can get organic traffic and this particular post is very important for those interested in learning Search Engine Optimization. It has perpetually been subject to probe on how Google displays the Search Results after you search a particular term in the Google Search Box. I thought of sharing some basic ideas that are perpetually behind this intelligent search engine’s operational ways.
You have to know how a particular thing works before you can use it, that is why there is always a manual in an electronic device which will instruct you on how to use it. This post will serve as a manual that will make you familiar with Search Engine.
Google is the most used search engine but not the only search engine, there are other search engines which include Yahoo, Baidu, Ask, DuckDuckGo and few others. In this post, we will be using Google search engine as our case study.
The first thing I will like you to understand is that when performing a search on the search engine, Google for example. When you Google search, you are not searching the web, you are searching Google index of the web. The search engines have been doing some pre-work before you come around to search.
There are two processes you have to be familiar with before you can really understand how the search engine works, this process are crawling and indexing. The crawling process is done by the Google's Spider crawler, which means the spider visit a website and uses the link to visit other pages of the websites, and they bring all pieces of information gotten back to the Google server. After crawling has been done, the information gotten is then indexed on Google.
Until your page is indexed on Google it will never appear in the Google search results, so if you just create a new blog or website you will have to wait for a little moment for Google spiders to come and crawl your website or you either submit your website to Google by yourself which will actually be faster than you waiting. Once your pages are indexed you can now be found on the search engine, though this doesn't mean you will be on the first page when a keyword related to your website or blog is searched.
At the user side, when you perform a search for example "red leather bag" , you typed this into the Google search engine and hit enter, the Google software will search through the index to find every page that include the search terms, there are always thousands of possible results that satisfy your search query.
The question is how does Google actually rank those web pages that are relevant to your search query. Google considers some factors in order to give you the best result for your query like the number of times the page contains your keywords, if the words appear in the title of the page, in the URL.
The quality of the website the web page is coming from is also a great factor that is considered. The page rank is also put into consideration, the number of quality links linking to the web page can give the web page an edge over other competing web pages.
All the aforementioned factors are combined together to get an overall score for each page, the pages are ranked in order of the score and then the search result is sent back to the user. All these processes are completed in less than a second
CONCLUSION
The process explained above is the way search engine operates, crawling is the first process, which means the crawler or spider fetch all web pages linked to a website, all the information gotten are kept into a database, this process is called the indexing. When a user searches with the search engine, the request is processed as the search engine searches through the already stored information in the database and return the relevant information as the search result.
