Here's the uncomfortable truth: 70% of the global workforce consists of passive candidates who aren't actively looking for jobs, according to LinkedIn's Global Talent Trends (via Pin.com's sourcing guide). That means recruiters who only target active job seekers are competing for just 30% of available talent. If you're only hunting on LinkedIn, you're leaving the vast majority of qualified engineers untouched.
Move 1: Switch your sourcing to GitHub. Tools that index GitHub activity can surface candidates based on actual contributions, revealing engineers who are invisible on LinkedIn because they haven't optimized their profiles for recruiter searches. According to Zumo's analysis of 685,000+ US developer profiles indexed from GitHub activity data, developers sourced via GitHub respond to personalized outreach at 25-40% — compared to 10-15% on LinkedIn. (Disclosure: Zumo is a GitHub developer sourcing vendor; this data comes from their own indexed profiles and may not generalize to all sourcing approaches.) GitHub gives you a direct window into a developer's skills, code quality, and work patterns — before you've ever spoken to them. That's context-building before you've even sent a message.
Move 2: Plan for multi-touch outreach. Most recruiters send one message, hear nothing, and move on. That's a mistake. According to GoPerfect Labs' analysis of outreach sequences sent through their platform, 31% of all positive responses came on the second or third message — not the first. The highest-performing sequence they observed was: LinkedIn InMail on Day 1 → email follow-up on Day 5 (different channel, same context) → a brief LinkedIn connection request on Day 9. That three-touch, cross-channel pattern drove 3x more replies than single-channel sequences. (Disclosure: GoPerfect is an AI outreach tool; this data comes from their proprietary platform analysis and may not generalize universally.)
The same GoPerfect data also found that messages referencing something specific about a candidate's background — rather than a standard "Hi [First Name], I came across your profile" opener — produced a positive response rate of 18.4% versus 5.6% for standard templates. Personalization isn't a nice-to-have. It's the whole game.
Put these two moves into action this week. Your pipeline will thank you.
