This site is designed to help businesses/personal websites by attracting potential customers to your website by using keywords (key phrases) that may be successful for you which you may not have tried. Some are even nonsensical but may help you if your stuck with the same keywords that aren't producing and/or you need to lower ad costs.

Help yourself to the free lists. These lists (based on average of .02 CPC) respond best to international/global market.  I found that choosing keywords for adwords by competition, local/global monthly searches, CPC, target keywords, etc., did not yield the expected results.  It was only through experience and vetting, that I developed these lists. 

If you wish to increase your traffic further by top-tier keywords, feel free to contact me(list@a-keyword.com).  Best wishes on your endeavors.  I Hope at least some of these keywords help.
