LinkedIn Prospecting for Recruiters: Find Candidates Who Want to Move

The candidates most worth recruiting are rarely the ones actively applying. They're performing well at their current job, open to the right opportunity, and passively signaling that openness through how they behave on LinkedIn. Reachr reads those engagement signals and surfaces the candidates showing the strongest intent to move — before they show up in anyone else's InMail queue.

What "Passively Open" Actually Looks Like on LinkedIn

A passive candidate who is genuinely open to a new role behaves in predictable ways. They don't change their profile to "Open to Work" — that flags them to their current employer. Instead, they:

• Engage with content from companies they find interesting — likes and comments on posts from employers in your client's space
• Post thought leadership that increases their market visibility — a signal they're building an audience outside their current company
• Connect with recruiters, headhunters, and people at target companies more frequently
• Engage with startup content or funding announcements in categories adjacent to their current role
• Update their profile in subtle ways — adding skills, refreshing their bio, updating a project description

Each of these behaviors is observable. Together, they paint a picture of someone who is quietly looking — not ready to apply, but open to the right conversation.

Why Keyword-Only LinkedIn Recruiting Misses the Best Candidates

Recruiting on LinkedIn by keyword and title filter is the fastest path to a list of busy people who don't want to hear from you. The problem: every recruiter is running the same searches, sending the same InMails, to the same people. Senior engineers with in-demand skills receive 15–25 recruiter InMails per week. Most go unread.

The candidates who reply are either less competitive (actively job-hunting with fewer options) or warm for a specific reason — you've reached them at a moment of genuine openness. The signal-based approach is how you find the second group at scale.

How to Use Engagement Signals to Find Passive Candidates

Step 1: Map the Signal to the Role

For each role you're recruiting for, define what "passively open" looks like behaviorally:

• Senior engineers: Engaging with startup content, commenting on funding announcements, sharing developer tool posts from early-stage companies
• Sales leaders: Engaging with go-to-market content, commenting on growth playbooks, posting about their own sales philosophy
• Product managers: Active on product strategy content, commenting on launch posts from companies at interesting stages
• Marketing leaders: Engaging with brand-building content from challenger brands, sharing market analysis

Step 2: Use Reachr to Surface Signal-Active Candidates

Query examples for recruiter use cases in Reachr:

• "senior engineers engaging with startup content"
• "product managers reacting on early-stage company announcements"
• "growth marketers engaging with SaaS content"
• "sales directors reacting on Series B startup posts"

The profiles returned are sorted by signal recency and intensity. The ones at the top have been most actively engaging with content suggesting openness to new opportunities — right now.

Step 3: Personalize to the Signal

The recruiter message that converts references what you observed about their interests, not just their current title and company. "I noticed you've been active on content from companies like [Company X] and [Company Y] — I'm working with a founder-led company in that space that's looking for a [Role]."

This message works because it shows the candidate that you understand what they find interesting, and you're offering something relevant — not just a role that matched their keywords.

Using Trigger Events for Recruiter Outreach

Engagement signals are most powerful combined with trigger events — moments that increase a candidate's openness to a conversation:

• Recent performance cycle end: Q4 and Q1 see spikes in candidate responsiveness following annual reviews
• Company layoffs or restructuring: Even well-performing employees re-evaluate options when peers are laid off
• Funding announcement at their company: Employees assess whether the new round changes their equity and growth trajectory
• Competitor company raise: Talent at your target company suddenly has an attractive alternative option — they become reachable

The Recruiter Outreach Message That Gets Replies

"Hi [Name] — I saw you've been engaging with content from [type of company] lately. I'm working with a [stage/type] company in that space hiring for [role]. Given your background and what you seem to find interesting, I thought it could be worth a conversation. No pressure — are you open to hearing more?"

What this does: it references observed interest without stating you've been analyzing their activity; it leads with their interests, not your client's needs; and it ends with a low-commitment ask.
