How does Search Engine work?

The Search Engine has four major functions are:

• Crawling
• Indexing
• Calculating the Relevancy
• Displaying the Results  on the Search engine result page

All the search engines use their own program called crawlers or spiders. The function of a crawler or spider is to read the source code of the website (HTML) and store that information on their local database called local servers. This technique is called the “Crawling” of the website.

Generally, a website crawled 3 to 4 times once a year. After the crawling process, Indexer takes the data from the local server and arranges them in proper categories like hotels, hospitals, schools, restaurants, etc. This indexed data is stored in the main database. This process is called “Indexing“. 

The Rank algorithm of a search engine is a program that ranks the website according to the website’s relevancy like fresh content, updated content, unique content, and no duplicate content.  Now, when a user types a search query (keyword) in the search engine, the search engine matches the search query (keywords) in their main database and presents the website information containing the keywords according to the rank assigned by the Rank Algorithm.
