People use different words when they search for online content. These search terms are called keywords.Keyword research tools can help you discover topics that people are currently searching for that are related to your expertise.

There will be less competition for the 'long tail' than the short list of most popular terms and key-phrases.Tip: Look at how your niche keywords may intersect with a holiday or current event. It's a great way to pick up current interest traffic!

Proper keyword researching has become a complex task. Nowadays, if you check your visitor stats on statcounter or any other website tracking service, Google doesn't even show you the keywords that your own visitors have used to find your website/page (if that visitor is logged to gmail, youtube, google+. etc). Google recently took this measure to help protecting the privacy of their users. I recommend using drop-down suggetions keywords combined with Google Keyword Planner Tool for an effective keyword researching campaign.

Hope this helps..
Cheers!
