Review about Sitechecker by Edgar Cardoso
After two months there were noticeable improvements in rankings and organic traffic. Backlink and Rank Tracker make it easy to monitor changes, but our website needed also regular SEO audits. We decided to run Sitechecker Audit once a week and it also contributed to the improvement of our results. This audit comes really handy and allows for quick and effective on-site optimization.

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.
Sitechecker includes JavaScript rendering and can crawl most SPA websites. However, some websites have preloaders that last too long, so Sitechecker can’t scan them.
The Google PageSpeed Insights test, which is a part of the on-page SEO audit, contains Core Web Vitals metrics.
As often as necessary. However, note that after each change, the crawler will restart automatically.
