I have two adult sites. One of them is new, one is old. Old one used to be at 1st place on G. I do SEO for it, backlinking, and plus my domain name is my main keyword. Now, my new site is 1st for that keyword, without any SEO, without any backlinks, without keyword reach domain... I`m confused. First i thought that google penalized me for some reason, but my old site is at 3rd place now.... Any ideas?
