It might be a very basic question for most of you, but I'm starting doubting about my process. When I decide to write a new article, I first check how many search queries a keyword gets into Google Keyword Tool. If there are a lot of queries, I will think about an article to write around that topic. But I believe there is a much more efficient way to establish what to work about. I don't know, for example a tool that tells me the most popular searches based on a keyword (e.g. I put travel and I retrieve "which are the most dangerous travel destination of 2014?") What's your best practice, guys?
