My team has developed a keyword difficulty SEO tool that has dove deep into keyword research and analytics for people's websites and we've over the last couple years have also created an action plan generator that gives you specific step-by-step instructions on what to do specifically for your site+keyword to boost your ranking. We are always looking to improve our system though and would love to know what everyone looks for (important metrics, information, etc.) when picking an SEO/keyword difficulty tool to use for their site(s). Thanks in advance.
