How to find broken links effectively?

[ani2002]

There are a number of tools you can use to identify broken links, many of them free.
ex : Google Analytics, Xenu
Create a report and track your changes
Analyze data and decide which pages should be redirected
Redirect in CMS

Repeat the above process to redirect all the broken links and update the Broken Link Redirect Report.
Mission accomplished!

I don't prefer Xenu. Have tried it though, didn't like it.
