However if you'd like to know..
http://mustang2016.com - I get traffic to that site from "1969 Ford Mustang Fastback"
I searched '1969 Ford Mustang Fastback' in Google. Could not find mustang2016.com in the first page !!! Are you getting good traffic from even second page or behind ?
Are you seriously not getting the point? I used "1969 Ford Mustang Fastback" as an example.. The car is 40+ years old, and people are still searching for it.
My website is Mustang2016.com Which has NOTHING to do with 1969 Ford Mustang Fastback. However the 1965 - 1969 Ford Shelby GT350 does have something to do with my website, and hence why I receive traffic for both.
Mustang2016.com is also newer and hasn't had much social marketing promotion done, nor back linking. Specially considering "Ford Mustang" is a much broader topic than "Toyota Supra", it's a tad harder to get on the first page.
This thread also has nothing to do with mustang2016.com so I don't understand why you continue to pursue it.
