To research keywords, consider using Google's Keyword Planner. The tool is free. Although, Google's Keyword Planner tool is targeted for paid ads, it can also be useful in researching potential keywords for organic searches by your audience. The tool breaks down keen (competition) level into low, medium and high.
These levels indicate the bidding difficulty level, which typically correlates to the search volume results.
Generally, it is more cost-effective in the aggregate to filter and focus on the low and medium difficulty keywords.
