I hope you would have already used this tool once in a while but now it doesn't require creating account moreover useful data is being shown again. Do you think more factors should be included to check the competition of the particular keyword? And how useful this tool is to you so far.
For my niche research such as keywords and stuff I use micro niche finder. It has always been solid for me.
Backlinkwatch serves a different purpose. Nichewatch serves you data required to analyze keyword competition on the web.
