Most of the time when people talk about keyword research, they focus on the Google Keyword Planner.
And since everyone is using the GKP in pretty much the same way, most business’ are going after the same exact keywords.
Here’s a list of 33 untapped keyword sources (or methods) that will help you reach more customers…
1. QuestionSpy uncovers every question
QuestionSpy will show you all the questions that your market is asking. It can be used to uncover general questions as well as specific questions buyers are asking.
Just put in a term or topic and let the software pull back all the results.
You can then target the questions directly, as keywords, or use them for brainstorming new seed terms and run them through QuestionSpy again for even more results.
2. Amazon Look Inside reveals reader terms
Amazon Look Inside is an excellent, but overlooked place to discover relevant, long-tail keywords.
Just head over to Amazon (and no Amazon app store api access is needed) and do a search in Books for your topic.
Then just click on the titles of the books with relevance to see if they have Look Inside enabled.
Finally, click on the Table of Contents and Index sections to see a huge list of related keywords that you can target. (works best in Chrome.)
3. Bing Ads Intelligence finds hidden gems
The Bing Ads Intelligence Tool is free to download, and works directly with Microsoft Excel.
It’s possible to run this keyword software on both Mac and PC, and it’s surprising how many people overlook this and focus solely on the Google Adwords Keyword Planner.
Once you have downloaded and installed the extractor Add-in, just input some keywords into Excel. After you highlight the keywords, click on the More Research icon to display a list of unique keyword tools from the ribbon selector.
There is also an option in the plugin to get the search volume for all of the queries. While Bing doesn’t have the number of visitors as Google, the potential to estimate keyword popularity for both desktop and mobile devices. (This includes android searches and ipad as well.) I think at this time, it is only possible to get global monthly searches (exact match, not phrase match or local search counts) from Microsoft AdCenter.
You can also input a list of competitor URLs and get back terms related to your competitors. This works well in niche markets or any projects where you want to spy on your competition and find long tail keywords to use in your on-page seo and rank on the first page.
4. Moz Keyword Explorer suggests great new terms
The Moz Keyword Explorer allows you to simply input your seed term and get back 1,000 suggestions.
Most of you doing keyword research are probably familiar with Rand Fishkin’s work, and this is a good keyword planner alternative to get long tail keywords.
After your initial search query, just click the link to view all 1,000 search suggestions. They allow a few free searches per day to get you started.
5. Wikipedia produces lots of golden nuggets
Wikipedia can provide some excellent search engine optimization keywords for content marketing if you know how and where to look.
First, just type in your seed keyword with a single letter of the alphabet and take a look at the highly relevant Wikipedia suggestions that show up.
Next, look at the References section for keywords within the article titles that you can use in your on-page seo. (See tag #33 below for how to find paid keywords within this content.)
Don’t forget to keep searching in the Categories section for additional pages to find more potential keywords.
Another tip is to do a search at Google.com for “site:wikipedia.org keyword”. This will return all the pages that Google finds relevant for your keyword at wikipedia.com. Just look through the meta tag data and the titles to find even more great keywords and topics to explore further.
6. Wordstream reveals many related terms
Navigate to the free Wordstream keyword tool and input your seed term. (You don’t have to subscribe to use this phrase generator.)
Wordstream will bring back the top 100 keywords and phrases for your input term.
With 30 free searches per day, you can get up to 3,000 great keyword ideas from their proprietary advertising database. They don’t provide monthly search volume data, but you can get that from GKP.
7. Adwords Ad Copy contains lots of fresh terms
While there are lots of websites that offer realtime and historical Adwords Ad data, we’ll focus on SpyFu in this example.
Just input your keyword and hit search.
You’ll notice that they also give you a nice list of related keywords, ppc data, price estimates, and bidding info just above their Adwords Ad data. This is a great place to generate even more competitive keywords that are related to your audience.
Scroll down to the “Most Successful Advertisers and Their Best Ads” campaigns section.
SpyFu does an excellent job showing you the split tests being performed by the advertisers. Just click on any of the Ad copy version buttons to see the actual ad copy for the ad. Each of these domains are optimizing their ad copy to improve their click through rate and lower their cost per click (cpc) while still reaching their target audience.
Hidden inside these ads are the top converting keywords (and the emotions to use in your content for a better user experience and conversion rate) for your competitors.
8. Magazine text reveals new and trending keywords
This method takes just a little bit of work, but the payoff can be huge when you uncover new and trending keywords with consistent average monthly searches.
Since keywords are just the language of your market, anything your market is reading and looking at (landing pages, books, tutorials, guides, social media, LinkedIn, display advertising, newspapers, ads, etc.) will influence their search behavior.
The first step is to locate a magazine related to your topic (and targeting the right audience) with a digital version.
The next step is to download the digital edition and copy the text to a file. The easiest way to build this report is to just highlight any text within the magazine and then hit Ctrl+A to highlight all the text within the magazine. Then hit Ctrl+C to copy all the text.
Next, head over to the Keyword Density Analyzer tool and choose “Text”, paste in your text, and click Submit. (Default settings)
Once that software processes your text, you will now have a nice list of long tail terms frequently found in the magazine to use as new seed terms for research or as inbound keywords.
9. Facebook and Twitter posts produce new keywords
First, login and do a search for your topic with “” around it. You may get autocomplete suggestions but you can just hit Enter also.
Next, scroll down the page, and keep scrolling, to allow Facebook to present even more results. Scroll as long as you like until you have a large page of results.
Next, hit Ctrl+A and then Ctrl+C to copy everything to your clipboard.
Next, head over to the Keyword Density Analyzer tool and choose “Text”, paste in your text, and click Submit to get a custom report. (Default settings)
Once that software processes your text, you will now have a nice list of keywords frequently found in Facebook posts (or Twitter) that you can use to get more organic rankings and website traffic.
Social media is one of the best resources to keep track of the conversations and learn about your future contacts, customers, and clients.
10. Google News reveals lots of readership keywords
Your potential customers read the news every day. Why not see what headlines and content are affecting their search behavior. You’ll also uncover brand new longtail keywords to target in your seo campaigns. While we could use sites like Aol, Yahoo, MSN, or other WordPress blog news sources for this tip, we’ll just highlight Google News.
Just navigate to Google News and type in “keyword*” and hit Search.
In addition to great keywords, you’ll also find excellent topic ideas Google will point out for your content and related topics to get even more prospects in front of your offer.
11. Forums show you how fans talk
Forums are places where people hang out, ask questions, and talk about things they are passionate about. While casual surfers might use Google to look up information, those who take the time to become part of a forum community are usually much more passionate and knowledgeable about the subject.
That makes these great places to pick up the right keywords for your ppc research or search marketing.
Once place to start is BoardReader. Just input your term and hit search. It will bring back results from many different sources, including forums, which have plenty of search traffic.
Next, head over to Google and type in “keyword forum”.
Once you’ve selected a forum, copy the URL.
Next, do a search at Google like this “keyword site:theforumsite.com”
Next, copy the full URL in the address bar in your browser and paste it into TagCrowd.
Change the “Maximum number of words to show?” to 1,000, and click Visualize.
You will now have a Tag Cloud mapping your words from the conversations of those inside the forum for the topic you searched on. (Tip: Making sure your content includes these keyword suggestions is a great way to improve your quality score and lower your ad cost.)
12. Google Related uncovers hidden brainstorm terms
At the bottom of every Google search their is a list of terms Google believes are closely related to your original term. This is an excellent place to find topically themed related keywords.
You can manually drill into each of these suggested terms to find even more popular keyword terms, or you can automate this process with a software tool like KeywordMap Pro.
13. Q&A sites produce great keywords
You can also use the text analysis methods of #9 and #11 to either create a list of common keywords or a tag cloud of most common terms from these results.
14. KeywordTool.io brings back thousands of typed in keywords
KeywordTool.io is an excellent keyword finder search suggest tool that you can use to scrape Google, YouTube, Bing, Amazon, and App Store auto complete keywords.
Just input your seed term and choose your Google property and language.
15. Google Webmaster Tools shows you keywords you can target
Google Webmaster Tools is a great way to find keywords you’re already ranking for, but not ranking well.
While this isn’t a tool you can use before being setup correctly, we wanted to include it since it provides excellent data for keywords your site is already ranking for, that you’re probably not even aware of…yet. You can also get a better picture than Google Analytics for your individual keyword click-through rate and an evaluation of your optimization efforts for the keywords you are tracking.
16. SEMRush delivers quality keywords from a large database
SEMRush provides excellent data, even if you don’t have an account.
Just input your seed term and click Search.
They’ll give you related keywords and also the ad copy of your competitors. You can use their data to judge keyword difficulty also. Clicking on the URL in the ad copy will bring up a search for your competitor.
You can then click on Organic Research to find a list of all the keywords your competitors are ranking for also, which usually come from the content your competitors have researched and written about.
17. Google Correlate digs up lots of related keywords
Google Correlate is probably one of the most underutilized keyword research tools.
It doesn’t bring back thousands of results like some of these other tools, but what is does bring back is often fresh and very different, though related.
It’s a great way to brainstorm for entirely new topics your market is interested in.
Just input your seed term and click on “Search correlations”.
You can also exclude your seed term to find even more correlations that are broader, but still related.
18. Targeted Content + KDA = Hidden Keywords
Using the Keyword Density Analyzer, you can essentially take any text, whether it be from a book, .pdf file, slide, comment, etc. and get a list of common terms (keywords) back.
To harness this, just create a running text file (Notepad works fine) and just copy and paste relevant text from sites you visit. (Ctrl+A then Ctrl+C)
By keeping this running document, you’ll be able to analyze it and find the most common keywords that show up again and again for your market.
19. Google Trends reveals fresh, new trending terms
The #1 search engine in the world just gives away fantastic trend data…yet most people still don’t use it for keyword research.
That may be partially due to the user interface, or just the misunderstanding of how valuable this keyword data really is.
Navigate to Google Trends and type in your topic or keyword and click Search.
At the bottom of that page, you’ll have a list of keywords (broad match) that are trending. You can get even more keywords by downloading the .csv results.
But the real tip here is to play around with the Location, Categories, Time Range, and Google Property filters. Unlike most Google tools, you don’t need to even input a keyword or topic to get results from Google Trends, which makes it the perfect notification and monitoring tool for your keyword research.
20. Wordtracker Free Keyword Tool shows low competition terms
Wordtracker was one of the original keyword research tools available online (alongside Overture), before Google created their Keyword Planner tool.
Just about every seo book will mention Wordtracker, but it has gone overlooked recently. The data from Wordtracker comes from a unique set of sources and includes relationships with smaller search engines like Dogpile.com and Metacrawler.com.
Type in your keyword term and click submit to get a nice list and also some nice metrics from their free keyword tool.
While you won’t get back thousands of results, it only takes a second to get the results and even if you only find a few keyword gems, it is well worth the extra few minutes to check.
21. Soovle uncovers multiple suggest engine keywords
Soovle isn’t pretty. But it does a good job of grabbing keyword suggesting results from 11 different sites simultaneously.
It’s fairly self explanatory as most of these tools are. One thing to note is that you can click the download icon to download all results.
22. Amazon research reveals fresh product and topic key words
Type your topic or keyword into Amazon.com.
Click on a product that your market would be interested in.
Scroll until you find the Product Details section and click on the most relevant category. (They have a site map of all categories as well.)
Now that you’re on the Bestsellers page (highest conversion rate) for the category, click the bestselling items and look for keywords in the Title, Description, Features, and Comments (negative comments too!)
While this does take some time, you’ll discover exactly how your market talks about the bestselling products and services they are interested in. These are the keywords and topics you want to target to get their attention on your products and services.
One more thing…don’t forget to check out this post on how to do keyword research on Amazon as well.
23. Competitor URLs + GKP = New Keyword Ideas
There are some creative ways to use the Google Keyword Planner that will result in unique keywords that most of your competitors will overlook.
Navigate to the GKP and input your competitor’s URL.
Under Keyword Ideas, you can click to sort by Avg. monthly searches (exact match). These are excellent keyword ideas that Google has recommended based on the content of your competitor’s page. You can repeat this for different competitors or different pages of the same competitor to get even more keywords.

Once logged in, the results are displayed in an easy to read table with lots of additional data for each keyword.
27. Google Alerts notifies you of related content with keywords

28. YouTube Suggest shows you fresh terms from video searches
Keyword Tool Dominator has an excellent YouTube Suggest scraper tool online.
Just input your keyword and hit the search icon. The KTD tool will then grab the results and bring them back. You can then add them to your Keyword List and repeat the process.

29. Trade Journals deliver industry specific keywords
This method is very similar to #8, with the key difference that instead of using a magazine, you’ll be using a trade journal.
To get started just search with “keyword trade journal” or “keyword trade magazine” or “keyword trade association”.
Once you have located a digital copy of the trade journal, you will repeat the steps found in #8.
This is an excellent, but mostly overlooked method to find top industry specific terms.

32. GKP + Fresh Thinking = Fresh Keywords
To get fresh and overlooked keyword ideas from the Google Keyword Planner, you need to use the site in a unique way.
One GKP feature that doesn’t get talked about much is the Multiply Keyword Lists feature.
Just add the number of columns and then input seed terms into each column. Don’t worry if they all won’t make sense. We’ll let Google look and see if anyone has ever typed in those terms.
This can be especially helpful if you’re targeting local keywords, as you can input city, state, and zip codes with your keyword terms to find the most common variations.
This is also especially helpful when users input terms in reverse order of what you would assume. (i.e. “hooks fishing” instead of “fishing hooks”)
33. Buzzsumo brings back great keyword ideas
Buzzsumo helps you find the most shared content on the web. By analyzing the titles of the content, you can find great new keywords, ideas, and content hooks.
