We visited brokenlinkcheck.com, we tested tomydna.com and we compared it to the error reporting from sitecozy website checker.
Result from brokenlinkcheck.com
Brokenlinkcheck.com successfully found the malformated URL, an external URL that does not work and an internal URL that does not work. Two first errors returned “bad host” and the last one returned a 404
It found 3 errors.
Result from Sitecozy website checker:
The sitecozy website checker found 10 errors for the same website. The error message are much more meaningful. Also, the SiteCozy website checker shows the mixed content error when an internal link is in HTTP and the host page is in HTTPS. If I withdraw the mixed content errors, there are still 5 errors. It is more than brokenlinkcheck.com. It looks like brokenlinkcheck missed 2 404 not found errors returned by image URLs. Maybe, brokenlinkcheck does not check image URLs.
