Very low and expensive clicks

Im running a FB EXACTLY as john said to do it. The audience size is only 160k or so, ive only had 10 clicks for 45 bucks. Not sure whats going on any thoughts?

Hi FB algorithm took a couple of days to find its stride when I ran the 1% look alike bizop128k audience. It started at $7 per click the averaged at $3.65 per click with one day at $1.70 per click. The estimate of audience size seems to vary for exactly the same settings. I think this may be because the algorithm also tries to judge ad relevancy among other factors beyond the settings themselves but I’m not certain of whether that is an explaination here. I’m also open to suggestions on getting the cost per click on the recommended settings down to a value giving a positive ROI Nigel
