For my sites in the UK I would like some advices on the best way to do keyword research and competition analysis. I would like to have a tool to allow me to check how tough it's going to be to rank for a keyword with its competition.
For the keyword so far I've found :
wordtracker (27$ / month)
Traffic Travis (free)
Majestic Seo (free plan)
I would like to know if you have any suggestions and if free solutions (such as keywordeye + majestic seo) are enough to start.
