The best candidate for your client’s role is probably not applying for jobs. They are busy, doing well, and not looking. That is what makes headhunting worth learning.
For a solo recruiter, headhunting does not need a research team. It needs a repeatable method and a few simple sourcing strategies: search what you already have, widen the net with X-ray search, then reach out the right way.
Why Passive Candidates Matter
Passive candidates are not actively job hunting but would consider the right move. They are often the strongest profiles, because no other recruiter has put them forward yet.
The catch is finding them. In headhunting recruitment, good candidate sourcing starts closer to home than most recruiters think.
Step 1: Search Your Own Database First
Before you search anywhere else, search your own CV database. It is the cheapest talent sourcing you will ever do. People you spoke to two years ago may be ready to move now.
The problem is that keyword search often misses them. A CV that says “built data pipelines” will not show up for “data engineer” if you only match exact words. Search by what people have done, not just their title:
- By outcome. “Managed a system migration” instead of “IT manager”
- By context. “Worked in a regulated environment” to find healthcare or finance experience
Tools that understand meaning rather than exact words make this faster. EdgeTal, our app, lets you search your CV library in plain language and shows a match percentage with the area of the CV that matched. It is currently in a limited beta.
If your CVs are scattered across folders and inboxes, our guide to recruiting CRMs covers how to keep candidates in one recruitment database.
Step 2: Use X-Ray Search to Find New Candidates
When your database runs dry, Google X-ray search uses search operators to find public profiles on a specific website, without a paid account.
The basic formula is site: + job title + skills + location.
| Operator | What it does | Example |
|---|---|---|
| "quotes" | Matches the exact phrase | "site reliability engineer" |
| OR | Finds either term | ("nurse" OR "midwife") |
| - (minus) | Removes a term | -jobs -hiring |
| site: | Searches one website only | site:github.com |
These work the same way as the boolean search options in most recruitment tools. Match the site to the role: developers often share work on code sites, designers on portfolio sites.
Note where and when you found each profile. You will need it in the next step. For more ways of sourcing candidates, see our guide to AI sourcing.
Step 3: Reach Out the Right Way
How to headhunt candidates well comes down to one thing: a message that respects their time.
| Do | Don’t |
|---|---|
| Mention something specific from their profile | Send the same message to everyone |
| Say why this role fits them | Paste the full job description |
| Ask one simple question | Ask for a CV in the first message |
| Follow up once, after about a week | Chase repeatedly |
“Hi Sam, I saw your work on the payments migration at your current company. I’m working on a lead engineer role with a fintech client solving a similar problem. Would you be open to a quick chat?”
Be open about where you found their details. Under UK GDPR, people have a right to know how their information is used, so tell them when you first make contact. Our guide to individuals’ rights under GDPR explains more.
Conclusion
Headhunting gets easier the more you do it. Each search adds names to your database, so over time you build a talent pool of passive candidates that no job board can match, and your recruitment sourcing gets faster every month.

Frequently Asked Questions
What is headhunting in recruitment?
Headhunting is finding and approaching people who are not actively looking for a job, rather than waiting for applications. Recruiters use it to reach strong candidates for specific roles, usually through their own database, targeted searches and direct outreach.
How do you find passive candidates?
Start with CVs you already hold, then use X-ray search to find public profiles that match the role. Search by skills and experience, not just job titles, and keep notes on where you found each person.
Is X-ray search free?
Yes. X-ray search uses standard search engine operators, so you do not need a paid account. It only finds information people have made public, so results depend on how complete their profiles are.
