Exclude Product Pages from Ads

I’ve launched a new product as well as a newly started ads campaign where I’m focusing to figure out the actual bids efficiency. I’ve noticed that I got loads of impressions (and clicks) from Product pages, but the number of sales is terrible, whereas sales on TOS/ROS are pretty good but impressions are low.

How can I exclude PP from my campaign?

I’m currently using fixed bids and +100% TOS, +20% ROS.
