I like that you can have multiple campaigns running at once, and that it's very easy to add new pages or ads. It also integrates really well with Facebook pixel which is great for tracking analytics. We use popcorn metrics to track our marketing efforts through social media, so we can easily track success. We're able to analyze what's working and what isn't. The only issue that I've seen with popcorn metrics are some of the layout issues on their website. Some of the layouts look awkward when you want to add a new campaign. And sometimes it doesn't display correctly in some instances. Otherwise, everything else about popcorn metrics is excellent! We have been able to gain insights into how people interact with our website and what content they find most useful.
