What bugs me about most backlink checkers is that you can only paste in a clean list of domains. I typically want to copy ‘n’ paste a whole page, extract any domains from the text then see at a glance which ones have backlinks.
Is the backlink data accurate? Nope. But good enough is good enough for most uses: picking 1-2 domains for closer inspection out of a list of 100s or 1000s.
Backlinks.in is merely a ready reckoner. It queries SEOMoz
Linkscape Open Site Explorer and returns an estimate of how many unique backlinks a site has. If/when the data sucks, you know who to blame!
Try it yourself at www.Backlinks.in.
