Crawling
This is a program in the search engine that keeps on gathering information by roaming the world of the web. It collects data and information by visiting every website, this program is called Crawler, Bot, Spider etc.
This crawler scans hundreds of websites every second and keeps saving those data on its servers. It is a type of spider, then through interlinks, it keeps going from one page to another and from one website to another.
Crawler collects some of the following types of information.
- Page title description and information related to it
- Information related to which keywords are being used in that page
- Information about whether that page is Image or Video
- The website which is crawling, how many pages are there in that website and what is the speed of that page etc.
- Which page in the website has been updated and which page has been deleted.
Indexing
A search engine indexes the information after crawling it. All the information that has been collected while crawling is indexed in a list, it is installed in the database of the search engine.
Whenever you search any query in any search engine, after that the process of the search engine goes to that index and according to the information you have searched gives you the result.
Ranking
After crawling and indexing, the last job of the search engine is to determine which link will appear on which query. A search engine determines the rank of that page based on the quality and credibility of the website. In the language of search engines, this is called ranking. A search engine does this work on the basis of its own search ranking algorithm.
