Good advice on this below, but I would consider re examining the goal of the campaign. Going after just traffic can cause some serious issues if you’re not paying attention to the quality.
I do more paid search than social, but for example if I wanted to increase traffic for an e-commerce store that only ships to us addresses I could just do display ads on mobile devices in India. This will have a terrible conversion rate, but if i’m just looking for traffic then this would be considered success and the factors that make traffic expensive generally are the same factors that make it valuable.
Obviously you wouldn’t do something that silly on purpose, but this can easily happen with automated bidding like Facebook employs. If they’re optimizing for traffic, they could very well find some low quality traffic that no one else wants that is really cheap. This can then get into a feedback loop where according to the traffic goal it’s succeeding, so it doubles down and finds even lower quality (cheaper) traffic.
It sounds like you don’t have a lot of discretion on goals here, but I would definitely try to monitor conversions, or at a minimum look at time on site and bounce rates to measure traffic quality.
