Has this tool had any updates to its algorithm since it was created? From the dates on the posts it looks like it has been around for a few years. I am wondering if it is current for today's keyword competition.
Anyway, if it is current, I love this thing. It has kicked out a few keywords I though were good as being far too competitive. It has also confirmed others as good.
If it is current this things adds a level of certainty that I did not have before. What that translates into is more dollars being spent to build links for those keywords.
The link builders on BHW should get together and have something like this. More certainty should translate into more dollars spent on their services from all of us who buy link packages.
