For me, I am not guessing this works. I have lived it.
5 and half years ago, I launched a simple book in the Real Estate niche.
I started with zero authority and even without my face.
I did not have any following, nor a big audience of someone else to tap into.
I made a simple landing page for the book with the help of AI.
Then I asked AI to make me some videos and images talking about my book.
Then I started running meta ads.
All you need to do is talk about your products and the problem it solves.
Get people to visit your website from meta ads.
And watch sales roll in.
