How google crawl the webpages and indexing the webpages?

 

[dakshinaacademy]

Before you search, web crawlers gather information from across hundreds of billions of webpages and organize it in the Search index. The crawling process begins with a list of web addresses from past crawls and sitemaps provided by website owners. As our crawlers visit these websites, they use links on those sites to discover other pages. The software pays special attention to new sites, changes to existing sites and dead links. Computer programs determine which sites to crawl, how often and how many pages to fetch from each site.

Crawling:

When Google visits your website for tracking purposes. This process is done by Google’s Spider crawler.

Indexing:

After crawling has been done, the results get put onto Google’s index (i.e. web search).
