I have heard many people say “run a campaign for 3-5 days and if there is no sales, turn it off”. But everyone has different budget, so I think it’s very unclear.

In the past three months, I have been spending money ($1500) on Facebook ads and have only got 2 sales and maybe 10 add to cart. For me, I am still testing different strategies even though I know my products might be the biggest problem (clothing).

*I spend roughly half that amount on traffic and content view campaigns at the beginning, so I would say I spent $750 and got 2 sales.

When I run ads, everyday I spend around $30 to reach between 3000 - 3500 people, so the ads reach to around 9000 to 15000 in 3-5 days. Is this number of reach enough to tell me if I should turn it off if I got no sales?
