Fuck if I know, but if you want advice I say change your whole business model. This one is going nowhere.
I don't think that site is giving anyone any value. Maybe if you niched it like a tube with only old women, or black girls, only asians etc.
Otherwise no reason for me to come back.
A lot of categories say "No videos found" then you shouldn't have categories listed.
Really if your site is just general and not niched you're basically selling ice to Eskimos and you'll get nowhere.
Someone suggested taking that $500 to film some content and post it to Clips 4 sale, thats a much better idea and an actual business that gives value and makes money instead of site #10,000,000 giving away streaming porn clips to freeloaders.
Ride the tube is not a good name for an adult site. If you really love that name then honestly you'd be better off making a shopify store that sells tubes like this
Water Tube - Towable - Single & Multi Rider - HO Sports
Just trying to save you some money and time.
