For the free keyword research tool, I think we do all agree with that Google keyword planner has already established their market for a long time. All know Bing also introduced free keyword research tool and I have been working on that for one week. But after analysing the result and another phenomenon I found this tool is still young and it needs proper upgrade.
The data Bing keyword research tool has provided me infrequent as well as the lack of some bugs I think so.
Therefore, I assume that Google keyword planner is still good even for Bing search engine. But one believes that we should consider as well that Microsoft finally introduces a search engine which is little better that Yahoo and I hope they will improve their keyword research tool very soon.
On the other hand, Bing keyword tool still makes some signification role in search engine marketing as well as affiliate marketing.
