I was using MOZ for 2 months, and analyzed the crawl results before and after each modification. Have tried almost all possible crawlers, neither reports any problems like GWT.
Here is the thing.
The URL www.mywebsite.com/en/haiti is a 301 redirect to my homepage, yet somehow GWT says it links to www.mywebsite.com/haiti which is 404 page actually.
