In order to develop an effective search engine optimization strategy, you must conduct keyword research. As Google continues to update its search algorithm, it’s becoming more challenging to figure out what users are searching for. While you still can use tools like Google’s Keyword Planner to conduct keyword research, it’s become necessary to look to alternative sources as well to improve organic traffic.

Here are several untapped keyword research tools to give your search engine optimization strategy a boost:

1. Wikipedia
While traditionally thought of as an online encyclopedia, Wikipedia is also a rich resource for keyword research. To use this tool, simply type in a relevant keyword in the Wikipedia search query. If you take a look at the search engine results page (SERP), you’ll see a plethora of possible keywords within each Wikipedia entry. To take this even further, click on a few of the results and skim the first few paragraphs to find relevant keywords. Reading through the first few paragraphs will help you to identify longtail keywords, which Google prefers.

2. Google Autocomplete
Have you ever started to type a keyword into Google’s search query and noticed that Google offers several autocomplete suggestions? There’s nothing new about this feature, but it has become smarter over time as Google’s search algorithm continues to be enhanced. These autocomplete suggestions are based on search queries from real users, so it will provide you with an accurate representation of what people are looking for.

3. Google Related Searches
If you’re an avid Google user, you’ve probably noticed that Google offer a listed of suggested related searches at the bottom of a SERP. Pay attention to this as these related keywords are ripe for the selection. While this is similar to Google Autocomplete, using this tool is beneficial to you because it takes the keyword and mixes it up with other relevant keywords and phrases.

4. MetaGlossary.com
MetaGlossary.com is one of the lesser known keyword research tools, but it offers a wealth of information. The whole point of this website is to provide users with definitions. However, this tool will especially come in handy to marketers as it offers a lengthy list of related terms and phrases.

5. Amazon
No one questions that Amazon is king of the eCommerce world. One of the reasons why Amazon has such a huge presence on the internet is that they dominate just about any purchase-related keyword. If your business sells a physical product, you will especially benefit from using Amazon as a keyword research tool.

Keyword research is a necessary skill to master for marketers that want to improve their search engine optimization strategy. All of the keyword research tools mentioned above are free and easy to use. Take advantage of these untapped resources to improve organic search and increase awareness for your business.
