Now,i want to check whether my site have any bad link. I have try to use the "xenu" to check it.but some people said it is not well for a dynamic website,so i do not know which tool i can use. Anyone can share a tool with me?Thanks.
Did you actually try Xenu? I use it and it works like a charm! Great tool that every SEO should have in their bag of tricks. I use it to find 404s, 302s, 301s, as well as get listing of all URLs linked to by my site (internal and external).
I wanna add someting here. how do we detremine that the links marked by such tools as "bad links" are really bad links?
