Looking for marketing ideas

Hi all, I recently launched hashtini.com which is a simple landing page builder using your own hashtags for creators and small businesses. I have got a few paid subscribers through user interviews. I am thinking of running ads on FB/Insta/TikTok where my target customer segment is. I would like some ideas on how I should run these ads. Should those be lead generation, website clicks, or some other mode?

Any help, insights would be really appreciated.

Thanks
