The WordStream suite of Keyword Tools is an integrated and actionable set of keyword tools designed to help search marketers with keyword search, keyword suggestion, keyword grouping, PPC keyword research, keyword analysis, long-tail keyword research, and negative keyword discovery, going beyond the capabilities that a typical free keyword tool can offer.

Understandably – not everybody who buys Long Tail Pro will have the audience or platform to be able to promote as an affiliate. For example – a food blogger’s audience won’t care about a keyword research tool. So even if affiliate promotion won’t work for you – I hope I’ve shown how the tool will more than pay for itself if used for what it is intended for.

Don’t get me wrong. There are lots of other tools that I love and use (and promote) that also make a big difference in everything I do online now. But Long Tail Pro is probably THE most important. Getting search engine traffic to websites 101 doesn’t get more basic than doing good and proper keyword research. And nothing makes keyword research faster and easier than Long Tail Pro. Allow me to explain…
I use Ahrefs to find ideas for keywords to add into content, and content to create around keyword opportunities. I like how Ahrefs shows keyword difficulty, search volume, traffic potential (how much organic search traffic it’s possible to get when you rank #1 for a parent topic keyword) and lets you group keywords together to create lists. It’s really useful.
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.
