I never use the scrapebox link checker, the result is very effective and easy.
besides those 2 tools mention above, are there any tools for alternative?
I suggest you to Scrapebox link checker for I use this tools to check backlinks
You can check your back links on ahrefs.com and alexa.com.
I also use backlinkwatch.com.
I always use Ahrefs and it's the best in the business right now.
Majestic is pretty solid, but there is also a view in Google Webmaster Tools and a New Bing Site Explorer tool out there...
