How it works

how it works

Website crawler detects domain’s preferred version (http / https and www / non-www)

Before starting an audit, crawler tool checks different versions of the home page and identify which of them has 200 http status code.

how it works

Bot discovers and scans all internal and external links

Our bot finds all pages on a website. Crawler starts with scanning the main page. Using links on each page, it collects all available pages. If there are no internal links to a page, crawler won’t identify it. But how to crawl JavaScript (SPA) websites? Most crawlers can't scan dynamic websites, so they are only able to detect static response HTML. Sitechecker SEO crawler enables JavaScript rendering functionality, so JavaScript generated pages can be scanned.

how it works

Page Weight is calculated depends on website’s link structure

Page Weight parameter is calculated depends on PageRank algorithm, but only for internal links on your website. You can learn more details about this formula in original article of Sergey Brin and Lawrence Page or Ian Rogers guide.
