There's a risk of getting caught up in the ‘data' of keyword research. What we need to focus on is identifying the topics our target audience are interested in and the language they are using when searching for information and in asking questions.
Defining the keywords we're going to use is not only important for search engine optimization (SEO), but using the same language our potential customers use to describe their greatest desires and challenges will engage them and draw them into your audience.
Carefully reading over the tweets and posts in social media channels like Facebook, Twitter and Google+, where problems relating to your niche are discussed with friends and families, can provide you with a list of quality niche-specific keywords software tools would be hard pressed to duplicate. The hashtags used in heavily commented content can provide valuable clues, as can the comments themselves. Don your “Keyword Detective” hat and have some fun with it.
