What techniques do you guys use to generate site related questions to your customers website, how do you generate sample questions...there was a tool that i used before that is called keyword questions and With the Keyword Questions tool you can find the questions your customers are asking. Then use them with your SEO, PPC and AdWords campaigns to target long tail keywords and provide content that readers want to read and link to. But since you need to pay for this service now, what other tool would you recommend me to use (that is free)... thanks in advance and i hope that you can learn from this, because i used this for SEO tasks and it is working great
