Facebook ads is not the earning platform! It's a marketing platform basically!

If you don't gave a genuine product/service you'll end up burning money in the
campaigns without earning a single penny out of it!

Hope you get my point!

Run a small offer ...Make it so valuable that becomes no brainer for them to
take it...

Once you start getting the leads provide them value and them upsell them to
higher end services....

P.s :- I personally do that so it's a tried and tested formula

Work on linked in get clients for it get service charge minimum they pay 200$...

And that's minimum maximum it can go upto 2k

Sell something(product, service)

You don't you earn money selling good or services. Take your audience to an
offer that you have to sell.
