Starting a few websites to promote AI girlfriend - Need a few tips

Hey guys,
I've did different marketing campaigns on gaming niches, and now looking to expand it to AI girlfriend, as I see it's booming.
I've already tested different ways to promote it (top 10, ratings, PBNs etc.).

However I'm looking for a few tips what are the best ones in terms of results from click to sale, and click to reg?
I've tested many, but most of them didn't convert at all - and I just got a lot or registrations and 0 sales.
The only ones I've got any result for were candy.ai and heraheaven.

I've tested recently swipey.ai and they actually got good results finally, something that I can build more on as
the click to reg was very good and their funnel is pushing the user to a sale in the end.

Do you recommend any others that work well?
Do you have any tips about promoting it in a more scalable way?
If someone promotes AI products like me (but a lot better than me lol) I would be glad to get more tips and learn.


Thanks for any response!
