I setup a full website called prescriptions.today. Got a funnel going and tested with ads to onboard patients. Then did SEO and got it ranking.
The whole process took like a year to get it ranked. But i wasnt pushing very hard.
Now its generating about 40 patients a month and i disnt want it to go to waste.
When i was running ads I was selling the patients for $50 a visit, and the LTV was like $500.
I could acquire the patients for free from Google search or $50 landed from fb ads.
A terrible niche because its health and requires sooo many hoops to run ads and even get a gmb.
But now its running, and i wasnt doing anything with it.
I use grok to find a provider in florida and ca since most leads come in there.
I called the provider and hooked up a $500 a month rent fee. So they are renting the website from me to get the leads that are coming in from their state.
I will slowly invest time into this and add seo pages to increase search volume in other states. My plan is yo onboard providers in other states and charge them a rental fee to get access to the leads in their states.
Eventually ill be able yo run ads and sell them the leads from ads, growing the volume and my rev.
This is mot efficient because im not focused on it.
Im sure you could easily duplicate this idea in a different niche and make it much more efficient.
