The document discusses strategies for using social media to improve recruiting response rates. It recommends monitoring candidates' social profiles to find conversation starters about their personal and professional interests. The best channels for initial outreach are ones where candidates are most active and response rates are statistically higher, with less competition from other recruiters. Personalized messages focused on the candidate that reference something specific from their profile, like a shared interest, are more likely to get a response than generic messages. Building relationships over time through ongoing engagement can help when eventually needing to contact candidates for opportunities.
