At the bottom of this page are a link to a free keyword research PDF and a few more free background videos about understanding keyword research and using keyword research tools.
Variety is the Spice of Life

Traditional Keyword Suggestion Tools
SEO Book Keyword Suggestion Tool - our FREE keyword tool showing top keyword phrases. Features include...
- estimated search volumes
- estimated bid prices
- related search terms
- estimated search value (bid price * monthly search volume)
- data for the UK market along with the US market
- quick export of the top 1,000 most valuable related terms to CSV (which includes various keyword match types for paid search campaigns in the export file)
- Bing Ad Intelligence - brilliant extension for Microsoft Excel which puts a load of great keyword research data directly into Excel. Bing also offers an online keyword toolset here.
- Google AdWords Keyword Planner - recommends keywords based on a keyword you enter or a URL you have the tool analyze. Has a traffic estimator feature which shows the estimated bids prices and ad clicks for the top ranked AdWords ad. Allows you to check for [exact match], "phrase match", or broad match. In the past YouTube had a separate keyword research tool for it, but Google took that offline & folded the feature into their Display Planner. WARNING: Google at one point in time offered the best keyword tool, but they have become more adversarial with offering useful data to anyone who isn't spending money advertising with them, so if you are not running an AdWords ad campaign their tool may return useless trashy data.
- Keyword Keg - Firefox & Chrome extensions which integrate data from Google AdWords keyword planner in Google Analytics and various third party keyword tools.
- Wordtracker Free Keywords - free keyword suggestions from Wordtracker. Wordtracker also has a more advanced paid version, & sells top keyword reports. They have been one of the longest lasting SEO-related tool providers & were one of the original keyword tools founded nearly a couple decades ago. I also wrote a guide for them on coming up with creative keyword research ideas.
- SEMrush Keyword Magic - tool which comes as part of the competitive research tool SEMrush. Their database contains over 200 million keywords across 30 regional databases.
- Ahrefs Keyword Explorer - tool which comes as part of the link analysis & competitive research tool Ahrefs. Their database contains over 3 billion keywords from over 100 countries.
- KWfinder - low-cost keyword research tool.
- SERPs Kewyordini - quick and easy export like our keyword tool. appears to list more longtail keywords, but has a bit less coverage on some head terms.
- Keyword Discovery - free keyword tool from Trellian. Trellian also has a more advanced paid version of Keyword Discovery.
- 7Search - smaller database from their smallish PPC ad network
- Grep Words - API-based keyword tool.
- WordStream Keyword Tool - allows you to export a list of thousands of keywords for free, though acts as a lead generation tool & requires you to input your email address to get the keyword list. Their sales team is quite aggressive.
- Google Suggest scrapers
- Google Suggest Tool - shows frequently search for phrases starting with the words and letters in your query.
- Uber Suggest is a feature-rich tool which uses Google Instant keywords to generate suggestions.
- KeywordTool.io, Tejji & Infinite Suggest are similar to Uber Suggest.
- AnswerThePublic - similar to the above, but breaks the search requests down visually into sections of who, what, where, when, why, how & such.
- Huballin - similar to AnswerThePublic, but with a less graphical interface.
- KeywordShitter - questionable branding no doubt, but a useful tool for automatically bulk scraping Google suggest.
Keyword Valuation Tools
- Both Bing & Adwords offer CPC estimates in their ad platforms, though as mentioned above, Google's data is quite terrible as they aim to obfuscate data to make SEO harder. If you are a large AdWords advertiser they may show somewhat more accurate data, but they still tend to merge some words together & do other shifts as their goal is to get advertisers to spend broadly & aggressively.
- many competitive research tools like SemRush, SpyFu, SearchMetrics & KeywordSpy offer similar databases. Each service has its own strengths and weaknesses (database depth, regional coverage, data exportability, etc.)
Installable Keyword Databases / Desktop Software
These tools offer downloadable databases that you can install on your computer. One issue with these types of databases is they tend to have a bit of noise in them & are a huge download. But the nice thing is there is no recurring fee for the data after you buy it (though they may charge for updates).
