How to source candidates on LinkedIn: a daily workflow from search to first call
On this page
To source candidates on LinkedIn, turn the intake into a saved search with titles in the title filter and skills in the keyword box, review profiles quickly against two or three must-haves, message the strongest matches first with a note that names why you chose them, and track every reply so you can see which searches produce interviews. The skill is not finding profiles; it is choosing the forty people worth contacting and giving them a reason to answer.
This page is the workflow, from the first search to the first call. The strings themselves are in Boolean search strings for recruiters. Product details below are taken from LinkedIn's help pages as of September 2026 and change often, so check them against your own account.
Before you search: three answers from the intake
Sourcing goes wrong before the search box. If you start with only the job description you will match on its wording, and job descriptions are written to attract applicants, not to describe the people already doing the job. Get three things from the intake meeting:
- Target companies and teams. Where do people who do this work well sit today? Which competitors, which kinds of team, which size of organization?
- The two non-negotiables. Not the eight bullet points in the posting. The two things that would make the hiring manager reject a profile on sight.
- Profiles they have already said no to. Ask for two examples. Nothing calibrates a search faster than knowing what "close but wrong" looks like.
If the hiring manager cannot name any target companies, ask who they would poach from if nobody would find out. The answer is usually specific.
Set up the search so it keeps working
One good search, saved, beats ten fresh ones. A practical setup on LinkedIn Recruiter or Recruiter Lite:
- Job titles filter: current titles only for the first pass. Past titles bring back people who left the function years ago.
- Keywords: the non-negotiable skills, with synonyms in brackets.
- Companies: your target list as a first pass, then run the same search without it to find people at companies you did not think of.
- Location: set from the intake, including the commute or time zone limit, not only the city.
- Save the search and turn on alerts, so new matches arrive without re-running it.
LinkedIn's Recruiter help page on Boolean notes that the job title, company and keyword fields accept Boolean operators, and that very long queries can cause result problems. Keep each field doing one job.
The open-to-work signal, and its limits
Members can share that they are open to work with all LinkedIn members (which adds the photo frame), with Recruiters only, or with nobody. According to LinkedIn's help page, the Recruiters only setting is visible to people using LinkedIn Recruiter, and LinkedIn takes steps to keep Recruiter users at the member's current company from seeing it, while saying it cannot guarantee complete privacy.
Two things follow. Never mention that you saw the signal in a message the candidate's employer might see, and never treat its absence as a no. Many strong candidates never switch it on and still answer a well-aimed message.
Reading a profile in 30 seconds
Most time lost in sourcing is spent reading profiles that were never going to fit. Read in this order and stop as soon as one check fails.
| Check | Look at | Moves on if |
|---|---|---|
| 1. Scope | Current title and company size | The level or scale is clearly wrong for the role |
| 2. Non-negotiable | Current role description, skills, projects | There is no mention of either must-have and nothing that implies it |
| 3. Tenure | Time in current role | Joined in the last few months (note for later, do not discard) |
| 4. Location | Stated location and any remote note | Outside what the client agreed |
| 5. Hook | A project, post, move or detail you can mention | Nothing specific: still message, but lower priority |
Tenure deserves care. Someone who joined a new company recently is rarely ready to move now, but they may be in a year. Add them to a pipeline project with a note instead of skipping them.
Read profiles for evidence of the work, not for signals about the person. Photos, names, graduation years and gaps tell you nothing about whether someone can do the job, and filtering on them is how sourcing introduces bias before a single interview. Probe gaps on the call, the way how to probe resume gaps describes.
Decide who to contact first
Sort your shortlist into three tiers before writing a single message. It keeps your best message for your best candidates and stops you burning through the list in the order LinkedIn happened to show it.
- Tier 1: both must-haves visible, right level, and a specific hook. Personal message, written one at a time.
- Tier 2: both must-haves likely but not certain, or no hook. A shorter message built on a template with one personal line.
- Tier 3: one must-have visible, or recently moved. Hold for a second wave or add to a pipeline.
Check your ATS or CRM before messaging anyone. A candidate your agency spoke to last month, or one already submitted to this client by a colleague, should get a call from the person who knows them rather than a cold InMail. Double submissions are how agencies end up in fee disputes.
The message: what earns a reply
The full set of templates lives in LinkedIn InMail templates for recruiters. The principles that matter on any channel:
- Why them, in the first line. "Your post about moving the warehouse to cycle counting" beats "your impressive background".
- What the role is, concretely. Title, level, location or remote, and the range if you are allowed to share it.
- One easy ask. A 15-minute call this week, or a reply with a better time. Not "let me know if you or anyone you know".
- Short. A message that fits on a phone screen without scrolling.
An invented example of a tier 1 message:
Subject: Multi-state payroll lead, 900-person manufacturer
Hi Marcus, your note about moving a six-state payroll to a single
calendar last year is almost exactly the problem this role exists
to solve.
It's a payroll lead role for a manufacturer in Columbus, hybrid,
reporting to the controller. Range is $88-98k plus bonus.
Worth 15 minutes on Thursday or Friday? If the timing is wrong,
a one-line "not now" is completely fine.
DanaInMail rules that change how you send
Under LinkedIn's Recruiter and Recruiter Lite InMail policy, as of September 2026, you get a credit back for each InMail that receives a response within 90 days, and a reply of "Not Interested" counts. The InMail Improvement Period page says recruiters must keep a response rate at or above 13% on 100 or more InMails in each 14-day assessment period, and that falling short after a warning disables bulk InMail for two weeks.
The practical effect is the same as good practice: send fewer, better-aimed messages, and write them so that saying no is easy. A candidate who replies "not now" costs you nothing and is a warm contact next year.
Follow-up and tracking
One follow-up is normal; three starts to damage your name with a candidate you may need later. A simple cadence:
| Day | Action |
|---|---|
| 0 | First message |
| 4 to 6 | One short follow-up adding one new fact (range, remote policy, the team) |
| 7 to 10 | Try a second channel if you have a legitimate one, such as a work email the candidate published |
| After that | Stop, tag the profile with the date and role, and revisit in a later search |
Track four numbers per search, so you can compare searches rather than guess:
- Profiles messaged
- Replies (any reply, including no)
- First calls held
- Candidates submitted or moved to interview
If replies are healthy but calls do not turn into submittals, the search is finding the wrong people. If calls convert but replies are low, fix the message. The arithmetic is simple: an example desk that sends 40 messages, gets 10 replies, holds 6 calls and submits 2 has a 25% reply rate and a one-in-three call-to-submittal rate. The broader set of desk numbers is in recruiting agency metrics.
From reply to first call
A reply is the start of a screen, not the end of sourcing. Book the call inside two working days while the interest is warm, send a calendar invite with the role title and a line on what you will cover, and prepare two questions that test the must-have the profile could not confirm.
On the call itself, listen more than you pitch. The phone screen questions for recruiters page has the structure. If you take notes with a transcription tool, tell the candidate at the start; the consent guide has a line to read aloud. Interview Signal runs on your own computer without a bot joining the call, which makes that first conversation feel like a conversation rather than a recorded meeting.
Sourcing mistakes that are easy to miss
- Only searching current titles forever. After the first pass, search for the work in the keyword box without a title. The best candidates often have odd titles.
- Messaging the whole list at once. Send tier 1 first, read the replies, and adjust the pitch before tier 2.
- Hiding the range. Where you are allowed to share it, a range answers the first question most candidates have and filters out people who would decline at offer.
- Scraping or bulk-exporting profiles. LinkedIn's User Agreement restricts automated access. The account is worth more than the export.
- Letting the search go stale. If a saved search has produced no calls in two weeks, go back to the hiring manager with what you found. The market is telling you something about the brief.
Questions people ask
Can I see who is open to work on LinkedIn without a Recruiter seat?
Only if the member chose to show it to all LinkedIn members, which adds the #OpenToWork photo frame. Members who choose Recruiters only are visible to people using LinkedIn Recruiter, according to LinkedIn's help page as of September 2026.
Do unanswered InMails cost me credits?
On Recruiter and Recruiter Lite, LinkedIn returns a credit for each InMail that gets a response within 90 days, and a reply of Not Interested counts as a response. Messages that are never answered use up the credit.
How many profiles should I contact per role?
There is no fixed number. Work backwards from your own history: if your desk has needed about ten first calls to produce one submitted candidate, and one in four messages gets a reply, you need around 40 well-chosen messages. Track your real ratios rather than borrowing someone else's.
Should I connect with candidates or send InMail?
Use InMail or email for a specific role and a connection request for someone you want in your network long term. A connection request with a job pitch in the note reads as spam to many people and is easy to decline without reading.
