To drive search engine traffic, whether through organic search or paid search advertisements, you need the right keywords, plus a process to expand your keyword lists over time. That’s where our free tool comes in. WordStream’s Free Keyword Tool gives you hundreds of relevant keyword results, plus additional, actionable information like competition level and estimated CPC, all for free!
It would be great if you can provide comparative analysis of this tool with Google Keyword Planner. Since you’re using this tool so you can provide best comparison. One differentiation which I understood is that this tool works for yahoo and bing as well whereas Google keyword planner works only for Google but Google being a dominating search engine, gives the highest returns, so only this reason may not be enough to buy it.
