The team at E2M is taking this opportunity to analyze other significant (and free to use/try) keyword research tools out there. We are asking ourselves what data and logic should ideally go into keyword research, how this logic can be programmatically applied to the creation of tools, and what the best ways are to consolidate and use their output. Here’s a quick look at 25 other keyword research tools, some well-known and some you’d do well to know. These are not alternatives to the AdWords Keyword Tool on their own, but each of them performs some function of the AdWords tool in its own unique way, and all of them aid and abet your keyword research quite well.

I love Moz’s interface and how they give you data on the keywords. It’s easy-to-read, making it an ideal solution for both experts and newbies alike. They’ll show you both numeric and visual representations of a keyword’s monthly search volume, its opportunity for ranking, priority, and difficulty. They’ll also show you keyword suggestions and SERP analysis, which is fantastic and detailed.
So whilst Long Tail Pro has just continued to grow in revenue every single year and comes highly recommended, you may want to check if all the important features are fully functioning before signing up. Especially the KC feature (keyword competitiveness) as it is so fundamental to keyword research and making an informed choice on whether or not to go into a particular niche.
This is a rather crude metric because it presumes one can monetize all the traffic they receive AND one can generate as much profit per visitor as Google does. Anyone who could do both of those would likely displace Google as the first consumer destination in their market (like how many people in the United States start ecommerce searches on Amazon.com rather than Google.com).
I would like to get LTP but I’ve read that people have some issues according to Keyword Planner and Moz. Do you still recommend this tool? How accurate is it’s data comparing to previous versions? Does Keyword difficulty still works as it should? Maybe it’s better to wait untill some stability of this software? I don’t want to waste money for some tool which doesn’t work properly.

Hi – I’ve read your post with great interest. Not only am I happy for you and your success, it does provide a glimmer of hope to those of us who do have “other” ideas. I, too, have had an idea for a very long time now, but I have no idea how to go about “making it a reality.” I am not a programmer either… though I do know some html… I also remember the old days of having even a web developer holding domains hostage, never mind the site’s entire code. And, yes, that is one of the major things that stops me from even discussing things with a developer. I simply don’t trust them…

However, KWFinder has a couple of areas where Longtail Pro outshines it. Firstly, I like the fact LTP provides you with a suggested keyword competitiveness to target (as described above). More significantly, I don’t like the way that KWFinder restricts your number of keyword suggestions if you choose their cheaper pricing tier – it feels like they’re holding back some of the power of the software unless you pay more. With LongTailPro, you can see as many keyword suggestions you like so long as you’re within your monthly allowance.
For a long time, I wanted to develop a tool for content marketers that would assist in the process of coming up with blog ideas and subjects. Upon researching developers for this concept I had, I stumbled across  Long Tail Pro, and realized instead of developing a tool myself for fellow bloggers and content marketers, I would throw my support behind this one.
This comes with a monthly fee though, so why have that recurring revenue drain when you can just get MS or LTP for that matter on a one off fee. They are both virtually the same in my opinion. This is the only thing that is stopping me from buying the software. If the calculation of keyword difficulty was included in the one off fee, i wouldn’t mind paying the full $97.
What are people looking for on your site? These terms are keywords in the vocabulary of your actual audience and should definitely be added to your keyword list. Do not forget to look at the keywords people filled in that didn’t get any results: this was stuff people were expecting but didn’t find. You can look into the results of your internal search in Google Analytics at Behavior → Site Search → Search Terms.
Great Top 10 keyword research tools list. Thank you for posting Robbie! I really appreciated the feedback from the experts. There are a definitely a few tools here worthy of taking note of. I have also been using DYNO Mapper (http://www.dynomapper.com) as a keyword research tool. DYNO Mapper is a visual sitemap generator that delivers keywords on all pages of any site. The user simply inputs any existing URL into the system and it will scan thousands of pages.
