Ever since Google announced the impending demise of the AdWords Keyword Tool and their preference for its new avatar – the Keyword Planner, yet another hot discussion has sprung up in the SEO community. This time, strong adherents of the free-for-all ideology are riled at Google’s decision to make the Keyword Planner accessible only to marketers who’ve explicitly signed up to Google’s AdWords (which is one step more than having a Gmail account), taking it closer to being a paid tool in future! I don’t see this as a hindrance, because most other keyword (or other) tools require you to create an account and sign in before you can use them, even if they’re free. But if Google does it, we have reason to pounce on them, don’t we?

One possible problem is that although the Keyword Planner has some cool new features (including integration of the Google Traffic Estimator, which will be retired too), as of this writing, the indispensable Exact Match and Phrase Match features are nowhere to be found! Whole books will become useless without these, so I hope Google will eventually port them to the Keyword Planner. Nor do you see the “Include specific content” option, which is a life-saver for the adult industry, which spends the most on Google PPC.

We’re not here to dwell on the good and the bad of Google’s decision. I personally am elated that this debate has brought the crucial SEO function of Keyword Research into the limelight once again. There’s more to it than taking the first 10 results from the Google Keyword Tool and scattering them left, right and center in your content. Savvy keyword research is what separates strategists from headless chickens.

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.

1. Mergewords

Mergewords

This tool allows you to enter a collection of keywords in three columns. It will then generate a list of permutations of those keywords so that you can take them to another keyword tool or domain naming site to see what your next options are.

Pros:

  • The extra options allow you to select how you want the words to be separated from one another, including nothing, a space, a dash, a plus sign, or any custom separator. You can also wrap the words in quotation marks or brackets.
  • The tool is very user friendly
  • Very useful in conjunction with setting up a PPC campaign so that you can specifically target all permutations instead of using a broad match that may be too broad

Cons:

  • Mergewords doesn’t provide you with any data about the keywords; you will need to take the words to a different tool for that
  • No keyword recommendations based on similar interests are provided other than permutations of the columns that you included

Pricing:

  • Free

There, now. We’ve given you an overview of twenty-five cool keyword tools. Of course each of these has its own strengths and caveats, and at least for now, none can match the effectiveness of Google’s Keyword Tool, particularly in language, location, or device-specific results. Google gathers and analyzes vast amounts of data and as you know, the rich only get richer.

I also want to emphasize that Microsoft Excel and Google Docs perhaps play an equal, if not more important role in keyword research than any of these tools, because at the end of the day, the mountain of data you end up with is of no use if you can’t perform calculations, sort, filter, present or store it in a way that’s best suits the task at hand. Head over to Distilled for a comprehensive Excel for SEOs guide. Alternatively, bug this guy—he’s the Sensei who trains Excel ninjas in the dark of the night.

As search engine optimizers and marketers, we have to constantly keep testing and fine tuning search terms. Tools will always be there to help us collect and organize data but only humans can fully understand human intent, even if you argue that husbands can’t understand wives!
