How Search Engines Work

Before the understanding how search engine work, we shall  require understanding of all other algorithm factor and  search ranking factors. There are three way in which  search spider work.

• Spiders

• Algorithm

Working Mechanism of Spiders.

Spiders are also called robot, crawler. These crawler crawl the web. In simple words these are software that are used to fine and crawl the web.Spiders collect date from different web pages and store those date into the database of information called search engine index. Spider index different kind of document like html, php , css . Simply search spider index these document.

Working Mechanism of Users.

Users have variety of keyword search. Many users are looking for different kind of keyword search. Almost many user come to search engine for expecting their relevant search.  Some user are searching their content from desktop and some from mobile devices. Approximately 49 % user search their content from desktop and about 46 % are from mobile devices. Make sure that yours website  is Mobil and desktop friendly. If yours website is not a Mobil friendly, i recommend you simply install plugin that will keep yours website live to android  devices such as iPhone , Galaxy , Notepad . Many user are searching their content from Google search engine. Google has almost 80 % of market share and  has over five Billion query per day. Some query are never been search before has five million new query per day. They are long tail and short tail keyword search queries. As long tail queries are most searchable. I prefer to recommend long tail keyword search for SEO perspective. The user search keyword in different area of intent. These intent may be informative, navigational and transactional search.Only 10% are transactional and 10 % are navigational search while 80 % are informative search.

1. Informative search queries
2. Navigational search queries
3. Transactional search queries

when user type the word like ” what is SEO ” in search query, these kind of query are informative queries and its has a huge volume of 80 % search queries. Therefor many SEO expert prefer to  recommended long tail keyword. On the other hand Navigation queries are  those queries when user is looking for specific kind of website like www.google.com in search engine query box, The third and last search query is Transactional query.When user want to intent complete transection for example user having a mood of buying online and write a specific keyword of laptop or looking for download any kind of software, these are transactional search queries.

Algorithms Return Query Results.

Algorithms simply return search results to users.Whenever users perform their queries on search engine,google and other crawler response to that kind of query in real time.Algorithms show result base on keyword relevant and qualities of website, such as domain authority , page authority , original content, keyword density and many other factor. In simple words algorithms are computer programs that looks for clue to give you search result which you want.
