What Is Google Crawling And Indexing?

Deciding what you’re looking for and having Google return results to you may seem like an inconsequential thing, but there’s a reason so many pages show up in the results list when you do a search online.  Google compares the words you enter and returns or serves you a list of websites that match your keywords.  What is Google crawling and indexing to return search results?
The three key processes in delivering search results are as follows:

Crawling Bots

Crawling is the process by which Googlebot detects new and updated pages and chooses to add them to Google’s directory or index.
To accomplish the crawl, Google makes use of a large group of supercomputers to fetch (or “crawl”) billions of pages on the web.  The Googlebot is the name given to the crawling program.  It’s also known by other names such as bot, spider, and robot.  Googlebot uses an algorithmic procedure (e.g., processor instructions) govern which websites to crawl, how often, and how many pages to fetch from each site.
Crawlers look at webpages and follow links on those pages, much.  The bots go from link-to-link and bring data about those webpages to Google’s servers.
Google’s crawling activity starts with a list of web addresses from past crawls and sitemaps provided to them via businesses that own websites or blogs.  Once the bots go to a site, they look for links for other pages to visit.  The software is designed to spot newly created websites, sites that have made changes, and dead links.
It doesn’t cost for Google to crawl your site.  They keep the search part of their business distinct from Google AdWords (the earnings side).

Google Indexing Your Site

Googlebot processes each of the pages it crawls in order to accumulate a huge directory of each and every one of the words it gets as well as their location on each page.  In addition, Google processes information involved in major content tags and features (e.g., Title tags and ALT attributes).  Googlebot is capable of processing a number of content types, but not all.  They cannot handle the content of certain rich media files or dynamic pages, for instance.
Serving Results
As soon as a user inputs an enquiry, their engines look within the index for matching pages and send back the results believed to be very pertinent to the user.  The relevance is formed by over 200 factors, one of which is the PageRank for the assigned page.  PageRank is the degree of the importance of a page based on the incoming links from other pages.  In other words, every connection to a page on your website from a different site adds to your site’s PageRank.  Not all links are the same.  However, Google tries its best to ensure that every user has a great experience through detecting spam links and other practices that negatively affect search outcomes.  High-quality content receives the best kinds of links. Conclusion
In order to get your website positioned well enough for Google to rank it to appear on the first two pages of results, it is important to make sure that Google can crawl and index your website properly.  Visit Google’s website to help you determine what are the most suitable practices that can help you avoid common pitfalls and improve your site’s ranking.
