If you do any SEO at all, you’ll probably want to check your backlinks at some point in time. Either your own backlinks, or the backlinks of your competition. I recently came across a cool backlink checker called Blue Backlinks. It’s a free backlink checker tool that actually works, and it’s really useful for getting a subset of your backlinks.
All you need to do, is type in any top-level domain url and Blue Backlinks will go out and find a subset of your site’s backlinks. I’ve tested it on several sites, and it seems to bring back about 250-500 backlinks per site. What’s nice is that Blue Backlinks returns to you the exact url your backlink is on, the anchor text used to link back to your site and the number of outbound links (OBL) on that url. The idea being that the more OBL for a url, the less link juice your particular link will receive.
One other nice thing about Blue Backlinks is that it shows you the number of total backlinks to your site. I used to use Yahoo Site Explorer for this, but it’s well known that Yahoo under reports the number of backlinks you get. I don’t know how it calculates it, but Blue Backlinks does seems to give a more accurate number for total backlinks to your site which is quite useful. The other thing I like, is that all this backlink info can be saved to an Excel file. This makes it easy to retrieve all your backlink urls and you can do things like build more links to these links to make more powerful link wheels.
So what can you do with this backlink info? My favorite thing is do look at my competitors backlinks and try to figure out their link building strategies. Many of the popular link building services have distinctive signatures, so you can get a general idea of what your competition is doing.
