I have a facebook page with an increasing number of likes. I would like to find a way to make money out of it.
Since the page is about a niche subject (photos of a city), I'm thinking about using a service like Shopify to sell t-shirts related to this.
Do you have any other suggestion on how to monetize the page?
In addition, do you know when it would be best to start monetizing?
For instance, in order to maximize the sales of t-shirts it would be useful to know when it's the best time to publicize the products: peak of reached users? Peak of engaged users? Is 1000 likes a good starting point or would it be wiser to wait for more likes?
Those are all examples of questions I have in my mind.
