Get all backlinks to a site

... or at least as much as possible

[cangoou]

Hi. To analyse my own site and the sites of my competitors, I'm looking for a tool which can give all (or at least as much as possible) backlinks to a site. I know that google's "link:" is not working anymore, and yahoo-siteexplorer gives only 1000 links (often only from 10 or 20 domains), so a lot of links (some of them very powerfull) remain hidden.

Any ideas?

For your own site, Google Webmaster Tools (GWT) is the bomb.
For your competitors, siteexplorer.search.yahoo.com is the best you'll get, though of course it's not as good as GWT.
