I am managing a campaign on facebook ads. The targeted audience is very big. when I spend 20-35 usd/day on facebook ads our sales increase accordingly.
when we increase the budget above 40-50 USD/ day the sales stays the same. The frequency is still very low (1.6 ) but the extra budget don't give any more sales.
Even with 100 USD/ Day the sales stay the same as 35 USD / day
Thanks in advance
