Yahoo Clues has been around since 2010 as a keyword tool for Search Engine Optimization.   The tool gives deep demographic information about search trends for popular keywords.  Yahoo recently revamped the tool, adding more capabilities and making it more useful for SEO keyword research.  Below is a breakdown of how it works and why you should be using it. You can compare detailed information of several keywords in order to determine which will best improve your sites performance.  The revamped tool gives you insights throughout the world, not just the United States.  For example, Hurriyet and Sabeh are 2 of the largest media companies in Turkey: From Yahoo Clues we learn about the demographics of each keyword:
