What Has Changed with the Keyword Research Process?

Today's question comes from an anonymous caller, who asks about a video I made in 2013 about keyword research and SEO analysis. What has changed since I made that video? The 2013 video the caller mentions is available here (http://www.smartpassiveincome.com/niche-site-duel-2-keyword-research-seo/). The tools I mention are SEMrush (http://www.semrush.com/) and Long Tail Pro (http://askpat.com/longtailpro). Do you have a question about keyword research? Record it at http://www.askpat.com/.
