Back when I was working on my last Tube Project, I tried a link trade with one of those Review websites. I did not think it would make a difference but to my surprise they brought me in a decent amount of organic traffic.
Depending on where your at with your tube u might want to try it out, They list you on there website in return for a front page link to there review website.
This is the one I used -
https://bestlistofporn.com/
Just fill out the contact form
here and write a brief message with your name and website and alexa ranking.
It doesn't have to be this exact review website it can be any, just google porn review website and see which ones are on first few pages on google.
When you enter your email in the contact form make sure you enter the one from your domain webmail for example -
[email protected]
Try avoiding any gmail hotmail etc, by using the website webmail address you are confirming straight up that you are who you say you are.
This way they will take you serious as a legit webmaster. Hope this helps.
