Here’s what some of the biggest names in search marketing have to say about The Free Keyword Tool.
"The coolest feature it offers is that it allows you to download thousands of keywords at once."
- Aaron Wall, SEOBook

Believe it or not, The Free Keyword Tool is 100% FREE! So use it as much as you want, for as long as you like. And unlike some other “free” keyword research tools, we won't show you only a portion of the possible keyword suggestions and then make you pay for the rest. We will email you the entire keyword list for FREE!
People often ask us where we get the keyword data that fuels The Free Keyword Tool. The answer is we purchase the data through a number of search industry partnerships, which include:
Once we’ve acquired this keyword research data, we apply sophisticated statistical models to aggregate the different keyword data sets, applying various weightings and powerful semantic algorithms to compute related terms.
We use a CAPTCHA to verify that you're a real person interested in keyword analysis. This helps us prevent abuse so our computing resources aren’t bogged down by spammy bots, allowing the tool to run much faster like a truly efficient keyword generator should. To avoid filling out the CAPTCHA form, just sign up for a free account. It’s that easy.
First, here’s some background on us. Besides free SEM products, WordStream provides a full suite of paid Keyword Management Solutions, which includes PPC software, a keyword analyzer and a host of next generation keyword tools, for conducting proprietary keyword discovery, keyword research, keyword grouping and keyword organization. That said, the private keyword data that users plug into any WordStream product (paid or free) is never shared, sold or in any way integrated with any of our keywords tools.
Relative volume is our estimate of how often particular keyword phrases are searched on. The higher a keyword’s relative volume, the more frequently that keyword is searched.
We believe that The Free Keyword Tool provides the most comprehensive and accurate keyword suggestions and relative volume estimates of any free or paid keyword suggestion tool or keyword software on the market. The WordStream Free Keyword Tool was designed to generate more accurate keyword suggestions than the Google Keyword Tool, Google's AdWords Keyword Tool and other keyword tools by aggregating over 1 billion unique keywords, including:
This aggregated keyword data represents over a trillion search queries and hundreds of millions of related terms from diverse keyword sources. Using this method enables us to provide a more comprehensive and less biased mix of both head and long-tail terms for you to use in SEO and PPC marketing activities.
When pit The Free Keyword Tools against other keyword suggestion tools, there’s really no comparison. With our PPC and SEO keyword tool, you get:
Keyword tools in general are notorious for supplying dubious keyword results and inaccurate search volume estimates. In designing The Free Keyword Tool, our goal was to devise a means to overcome known keyword discovery tool problems, such as:
Here's a quick visual of why we think the Free Keyword Tool adds more value than a traditional keyword analysis tool:

In a nutshell, we think keywords should be free. For a more detailed explanation on this thinking, read WordStream founder Larry Kim's blog post on this subject.

Keyword research is an important step in the search and inbound marketing process, but not the only step. To succeed in the long run, you need actionable PPC and SEO tools and strategies to enable ongoing keyword discovery, organization and analysis...what we call "keyword management." Many in search engine marketing use Microsoft Excel for keyword grouping and organization tasks. Trouble is, Excel wasn't designed for this function.
