Sitecheckerbot checks different versions of the home page and identifies which one of them has the 200 HTTP status code. The crawler starts by scanning the main page and checking the robots.txt rules. Using links on each page, it collects all available URLs and checks them for issues. If there are no internal links to a page, the crawler won’t find it. The Page Weight parameter is calculated for each page. It demonstrates how strong internal link juice a specific page has.
