Finding my rivals best content:

Here's what I'm looking to do: I have a list of sites like the ones that I run, I'd like to be able to monitor those domains and have the most popular content(determined by social media *likely*) of those domains listed in my rss feed. I believe Buzzsumo can do this but they only have so many alerts for their $99 a month deal. What I am looking for is probably some super pimp Google Alerts thingie. I need help

I know a couple of resources. I can't remember their name. I will try and dig them out for you.
