In other systems I have used in the past (like Pardot), we were able to track engagements and interactions with leads via social links, social shares, etc. For example, we could create custom short links and tracking links in the CRM system, and when we published those links we could see not only which pieces of content a lead was viewing, but also where users where accessing the content from. This engagements also would tie into the lead scoring system.
I'm aware of the Marketo and Salesforce plugins, but those seem to be mostly used for social media listening/monitoring. We already have tools covering those areas. We are mostly looking to have more depth of interactions on lead profiles and also include social interactions in the lead scoring system. Thank you for any help!
