I started out over five months ago after reading and following the information you can find here and now my tube is getting approximately 400 unique visitors a day from Google alone.
It isn’t that much for sure, but it’s way better than I expected considering that I didn’t get any backlinks on my own, I just post videos embedded from other porn websites and I change the titles a bit and I just recently started adding some descriptions but I ain’t sure if it will help or not.
Of course it took me some time to get SEO rankings. I was adding videos every day for all that time but it wasn’t anything unusual or costly to do.
