I think keyword research is one of my strongest points as a PPC/SEO marketer, but at the end of the day everybody searches differently. It’s quite crazy how two different people will search for the same thing. Some people type full on sentences while others type just the most important keywords.
With that said, a solid way to get a feel for all the different styles that people search is to actually sit down and read peoples’ search histories. Whaaaat? You didn’t know that was possible? Well, it is.
