Something interesting happened today which I never noticed before. I typed in car history into Google expecting to get results back for everything that has "car history" in content. What I got instead were results for pages that has "vehicle history" in the content. I looked at the top of SERP to see if they have that comment "Did you mean XXXXX" or "Displaying results for XXXXX" but it wasn't there. This leads me to believe that Google is getting smarter and somehow knows that car history and vehicle history are the same thing so it display the results that I should expect to find. Has anyone else noticed this before? It seems to be a new thing I think. Thanks.
