Top 25 Web Tools for SEO Keyword Research
Keywords have gotten some criticism in recent years, thanks to spam tactics like keyword stuffing and low-quality content. But keywords are still the foundation of your SEO (and SEM) campaign, and it’s critically important that you take the time to choose them carefully. Keyword research is more than just brainstorming some ideas and assuming you’re on the same line of thought as your audience.
How do you know the keywords you’ve chosen will be profitable? How do you know how much competition there is, or if it’s possible to outrank the existing competition? Should you go short-tail or long-tail? The answers to all these questions lies in keyword research, and we’ve rounded up 25 of the best tools to help you pinpoint the keywords and phrases that will form a solid foundation for your SEO efforts.
- Google AdWords Keyword Suggestion Tool – Let’s start with the most obvious (and totally free!) tool for generating keyword ideas and gauging the potential for your keywords, and that’s Google’s free AdWords Keyword Suggestion Tool. You do need a Google account to use it, but we’re guessing that’s not going to be a problem. Simply enter some words or phrases in the search box and the AdWords Keyword Suggestion Tool will provide data on each as well as a slew of related recommendations.
- Google Trends – A little less obvious, but still offered by the massive web presence we all know as Google, Google Trends is actually a handy tool for keyword research. Once you’ve narrowed down some ideas, use Google Trends to figure out just how popular your key phrases have been around the web throughout a pretty impressive historical timeline.
- Google Correlate – Google Correlate is yet another Google tool and another step in the complex keyword research process if you choose to use it. After you’ve identified some promising Trends, figure out how those trends correlate to real-world events using Google Correlate. Are certain search terms more popular in winter? What other phrases have trend patterns that mimic yours over time? It’s not necessary to use this tool, but a pretty cool available option for doing things like planning seasonal campaigns.
- Wordtracker – One of the most widely known keyword research tools, Wordtracker is subscription-based, starting at $69 per month. Wordtracker also offers an ancillary tool, Keyword Questions, that helps you identify the questions people are asking around the web that relate to your target keywords—providing opportunities for meaningful conversations.
- Compete – Compete isn’t free, but you’ll get a slew of handy tools and resources at your fingertips, such as benchmarking, keyword research, web rankings (not based just on Google rankings, but any Compete metric) and more.

- Keyword Discovery Tool – Keyword Discovery compiles data from all the major search engines, so you’re not limited to seeing what’s been happening on Google (or better yet, you’re not limited to focusing your SEO efforts solely towards Google). A subscription here is comparable to Compete, at $199.95 per month.
- Bing Ads Intelligence Tool – Remember how we just mentioned not focusing all your SEO efforts on Google? We were serious about that—yes, Google is the giant, and it’s not likely to fall from its throne anytime soon.

So try out the Bing Ads Intelligence tool, which is downloadable and operates in a familiar Excel interface.
