How does website crawling work in detail?

[sabarina38]

Google crawling is a series of simple steps , which work recursively for each site. The figure shows Google's crawl, which begins with a check on a robots.txt file , which contains guidelines to follow. The crawler, usually aided by a sitemap, begins its crawling path and proceeds to analyze all new pages not yet viewed. It compares the URLs with those in its "backup" and continues its activity.

How and where to monitor crawling
Google Webmaster Tools offers an overview of your croatia whatsapp number database Googlebot activity, with statistics easily viewable in the “crawl statistics” section of the old Search Console view.

Here you can find the following information:

Pages scanned daily
Kilobytes downloaded daily
Time spent downloading a page (in milliseconds)
Crawl Budget

From the image, which shows an optimization of the performance of a website , it is possible to see that the pages scanned daily are inversely proportional to the download time of the page. The shorter the download time, the greater the quantity of pages scanned . Logically, in fact, it is understood the need of the search engine to optimize its resources for this operation. If the speed of the website is optimized, the crawler (in respect of other websites and user navigation) will be able to manage more pages during its scanning operations.
