Extended definition
X-ray search takes its name from the fact that you’re seeing through the front of a website to the indexed content underneath. Rather than logging into LinkedIn and searching within it, an X-ray sourcer runs a Google query like site:linkedin.com/in "data scientist" "Dublin" and pulls back public LinkedIn profiles that match.
It works on any platform that lets Google crawl its public pages. Sourcers use X-ray to get around seat limits on LinkedIn Recruiter, to hit niche sites that lack good internal search (conference attendee pages, university directories, GitHub, Behance, Dribbble), and to find candidates their competitors aren’t looking at.
X-ray is one of the fastest, cheapest advanced sourcing techniques — and it still works in 2026.
How X-ray search works
An X-ray string has three parts: the site restriction, the keywords, and the exclusions.
The site restriction tells Google where to look. site:linkedin.com/in searches only LinkedIn member profiles. site:github.com searches GitHub. site:meetup.com finds organisers and group members.
The keywords are standard Boolean terms — titles, skills, locations, companies. "machine learning engineer" "London" "PyTorch" narrows the search to profiles mentioning all three.
Exclusions remove noise. Recruiters, students, and agency consultants clutter LinkedIn X-rays. A clause like -"recruiter" -"student" -"looking for work" strips them out.
A full string for a staff-level backend engineer in Berlin might read: site:linkedin.com/in ("staff engineer" OR "principal engineer") Berlin (Go OR Golang) -intitle:"profiles" -"recruiter".
Platforms vary in how much they expose to Google. LinkedIn has tightened what it indexes over time — public X-ray results have shrunk but remain useful.
GitHub is wide open. Twitter/X is partial.
Meetup, Eventbrite, and niche communities often give the best returns precisely because they’re under-used. Good sourcers maintain a bank of site-specific X-ray templates and adapt them per role.
Why X-ray search matters
X-ray search gives small TA teams access to talent that larger teams pay LinkedIn Recruiter licences to reach. It also expands the sourcing surface area — a GitHub X-ray will find contributors who don’t maintain active LinkedIn profiles, and a Meetup X-ray finds practitioners active in local tech communities.
For niche or senior roles, X-ray often produces shortlists faster than LinkedIn because it lets sourcers pattern-match on things profiles rarely surface directly: conference talks, open-source contributions, published work. In cost terms, X-ray is free.
In capability terms, it’s a multiplier for anyone competent with Boolean.
Common mistakes and misconceptions about X-ray search
- Confusing X-ray with Boolean — X-ray is one application of Boolean, not a separate discipline. If your Boolean is weak, your X-ray will be weak.
- Using
site:linkedin.cominstead ofsite:linkedin.com/in. The first returns company pages, jobs, and articles. The second scopes to member profiles only. - Ignoring Google’s limits — Google caps results around 300-400 per query — if you’re not scoping tightly, you’re missing the deeper results.
- Relying on X-ray alone for LinkedIn — LinkedIn’s own search still surfaces profiles Google hasn’t indexed. X-ray complements LinkedIn Recruiter; it doesn’t replace it.
- Forgetting to exclude noise — A raw
site:linkedin.com/in "engineer"returns millions of results including recruiters, students, and career-change profiles. Without exclusions, it’s unusable.
Frequently asked questions
What is X-ray search?
X-ray search is a sourcing technique that uses Google's site: operator to search inside a specific platform — like LinkedIn, GitHub, or Twitter — from outside it, surfacing profiles that might otherwise sit behind a login or a limited internal search. Rather than logging into LinkedIn and searching within it, an X-ray sourcer runs a Google query like site:linkedin.com/in "data scientist" "Dublin" and pulls back public LinkedIn profiles that match.
Is X-ray search legal?
Yes. X-ray search only returns content that platforms have made publicly indexable by Google. You're seeing the same pages a logged-out visitor could see. It becomes a legal issue only when combined with scraping at scale in breach of a platform's terms of service — a different activity from running manual X-ray queries.
Does X-ray search still work on LinkedIn in 2026?
Partially. LinkedIn has reduced what it exposes to Google over the past several years, so X-ray returns fewer full profiles than a decade ago. It still works for name discovery, for finding profiles Google has cached, and for niche searches where LinkedIn Recruiter filters are too blunt.
What's the best platform for X-ray search besides LinkedIn?
GitHub for engineers, Behance and Dribbble for designers, Meetup for community-active practitioners, Eventbrite for speakers and organisers, and university or conference attendee pages for specialist fields. The less competitive the platform, the higher the return on X-ray effort.
Do I need a special tool to do X-ray search?
No. X-ray works in a normal Google search box. Paid tools like SeekOut, HireEZ, or SourceWhale add convenience — template libraries, enrichment, bulk export — but the underlying technique runs on free Google.
