How Search Engines Crawl and Index Websites

The search engine is a whole new world that works on certain principles and algorithms!!! Search engines, as we all know, are answering machines that solve queries with relevant content. Now the biggest dilemma is how search engines crawl and index. Apparently, search engines are continuously working on delivering the most relevant results and eventually improving how they crawl and index websites. Search engines like Google roll out hundreds of updates every month of little to some relevance, and understanding them in detail helps in strategizing and improving search visibility and ranking.

How do Search Engines Work?

Let’s take a look at the fundamentals of search engines.


Search engine crawlers, bots, or spiders, as we call them, are a part of an automated process as programmed by a search engine. Crawlers find newly updated content on web pages, new sites or pages, image, video PDF, and dead links. As a search engine’s crawler moves through your site, it detects and records links that are to be crawled later. From starting with web pages to following the new URLs through related links on those web pages, Search Engines Crawl and Index page accordingly. Crawler management
  • Ask Google to recrawl your URLs
  • Reduce the Googlebot crawl rate
  • Verifying Googlebot and other Google crawlers
  • Managing your crawl budget
The crawlers hop along the path to find new content and add it to a massive database of discovered URLs that can be retrieved later based on users' needs.


Indexing happens when search engines crawl and index links in a search engine database, or we can say, crawls the website. The intent behind indexing is to contribute to the ranking process by referring to and adding webpage content to Google for rankings consideration. A new page on a website can be indexed in multiple ways. One of them is by doing nothing. Or, since Google crawlers follow links, link new content with the existing content to make it discoverable by Google and considered for indexing. Once it indexes each page it crawls, it accumulates all related pages with the supposed keywords and their position on each page. The content is then compared to other web pages, having similar keywords to extract and store along with information in an organized form for a better interpretation by search engines as per the algorithm.

  1. Discovery - Google discovers new web pages to add to the index.
  2. Refresh - Google revisits webpages that are already indexed to find changes.
