I don’t have a business page. I don’t have a product to sell. What would you recommend for an ad?

I was just thinking brainstorming with myself of different ways to grow communities and I was just thinking New Year’s resolutions we’ve got so many people that are going to want to make a change! Now is the time to strike while the iron is hot!!!Get our names out there, get our voices out there. I am going to start plastering all over my TikTok account, wondering if anybody can think of a hook that I could use to get them over to my school community because I do give so much on my TikTok for free.
