Welcome.
I assume you are running an adult paysite. Make sure your site does look great, before you start to promote it anywhere. The design of the site is important, because most of the users will not join the ugly looking site even if it would have the best content available. I think it is ok to have a clean, simple looking site which loads fast, is responsive and is very easy to navigate.
If you need more traffic, then you should definitely get your site reviewed on the porn sites such as the thebestporn.com, rabbitsreviews.com and porninspector.com. Just google this phrase “porn review site” and you will get a tons of results.
You can also go to these sites and check out the other paysites and find where you can improve your own site. Especially take a look at the best rated sites, because these sites almost always have the best design.
If you have a really great content, review sites can bring you a lot of new visitors as well as the new members.
