Search engines have three primary functions:

  2. Index: Storing and organizing the content found during the crawling process. Once a page is in the index, it’s in the running and to be displayed as a result of the relevant queries.

Rank: Providing the pieces of content that will be best to answer a searcher’s query. It also means that results are ordered by most relevant to least relevant. 

Search Engine Crawling

Crawling is the process in which search engines sends out a team of robots known as crawlers or spiders to find new and updated content. Content can vary as it could be a webpage, an image, a video, a PDF, etc. But regardless of the format, content is only discovered by links.


Search engines process and store information they find in an index, a huge database of all the content which is discovered and deem good enough to serve up to searchers.

This relevance based ordering of search results is known as ranking. In simpler words, you can assume that the higher a website is ranked, the more relevant the search engine believes that site is to the query.


When a user searches for a word on a search engine like Google, the results that user is presented with is a series of websites that are relevant to the query and websites that have a solid domain. This is because the search engines use advanced crawlers that gather the information on every website and gathering every bit of content finds on the Internet.

Other efforts may include adding some unique content to a site by ensuring that the content is easily indexed by the search engine and making the site much more appealing for the users. Other techniques, known as black hat SEO, use methods such as link farms and keyword stuffing that tend to harm search engine user experience. Search engines look for sites that include these techniques and may remove them from their indexes.
