What is your main goal here? Are you selling products/Ecomm? I’ve found that you don’t need the 50 they have stated in the past for conversion/sales objective to work well. It depends on a number of variables. Based on your impressions, you aren’t spending much I’d assume so you probably aren’t going to be able to use actual sales as the conversion KPI.

I will actually layer multiple objectives on the same audiences well the best ones – conversions, traffic & reach typically as while there will be overlap, your reach is pretty throttled with just conversions. I want to still get top of the funnel prospects to the site, get them cookied and some signed up for the newsletter. With this strategy however, I typically will run 4-8 different Ads, but built 1-1 on the ad set level so that consumers will see a variety of ad types and formats all around that specific campaign. You can then drive up frequency without creative fatigue or annoying consumers too.
