When starting your online marketing campaign in paid search and organic, the first thing you must do is create a keyword list. This keyword list is the most important part of your campaign, besides the actual ad creative, of course. A good keyword list will include well researched keywords searched for by your customers. A great keyword list will include keywords that reflect the way your customers think and their behavior. But, whether good or great, your keyword list will determine how many impressions your ad receives, your click-through-rate, and the amount of conversions generated.


Once your core keyword list has been built, one of the hardest things to do next in keyword research is to uncover related keywords.


You might already have a fairly well-developed list of keywords, but there’s always room for improvement. There are always ways to come up with new more relevant keywords, new iterations, new misspellings, new topics, etc.


Fortunately, you’re not alone! There are keyword research tools that have been developed to help you find out what search terms your potential customers are using.


Here are 4 of the best (and free) keyword tools out there. Now go out there and build better keywords!



Google Keyword Tool

This is the classic tool used to generate lists of new keywords to target. Just enter in one or more keywords and the keyword tool will return a list of suggested related keywords. Google recently released a new version that organizes the resulting keywords by ad-groups. With one more click you can export all your new keyword data directly into your AdWords account.



adCore’s Keyword Tool

adCore is a leading AdWords automation software that empowers eCommerce businesses and SEM agencies to build large, highly targeted campaigns, run A/B tests on advertisements, and use bidding algorithms to generate conversions. And the best part is it’s completely free for up to 5 AdWords campaigns!

adCore recently launched a new free keyword tool. You can test additional search terms after importing a campaign from Google. The tool will give you the actual terms users searched for and the search volume of the suggested keywords, and then multiply your new list of keywords by sets. Of course, it also exports to Microsoft Excel and into Google or Bing. Plus, there’s a really cool adCore app on Google Chrome too.



WordStream Keyword Tools

The WordStream Keyword Tool is designed to help search marketers with keyword search, keyword suggestion, and grouping. It will also locate your most profitable keywords. It works with action tracking and a web analytics tool, so you can estimate future conversions and profits. You can separate keywords, group them to maximize CTR, and add negative keywords so you don’t get clicks from users that are not suited for your products or services.

WordStream gives users a 3 week free trial. However, it is very limited in terms of features.




Using search engine volumes and competition data, keyword suggestions are presented visually allowing users to pick out relevant keywords quickly and easily.

The free version of KeyWordEye limits users to 100 keywords. While it’s useful for high level ideas, it’s not a keyword research substitute. One interesting feature is the KeywordEye’s search volume estimator.
