Asking Buyers Where They Found You: Source Capture Habits
If every deal is 'the internet,' you cannot defend Marketplace, the website, or the lot. Asking buyers where they found you is a source capture habit, not a survey project.
The deal jacket says "internet." The rep says the buyer "saw it online." The GM asks whether Facebook Marketplace is worth the posting labor, and the room shrugs. That shrug is expensive. If you cannot tell Marketplace conversations from website forms, walk-ins, and repeat customers, you will either overfund a channel that is not producing or kill a channel that is. The fix is not a new attribution platform. It is a habit: asking buyers where they found you, logging the answer, and refusing to invent a source when they do not know.
Source capture is operational, not scientific. People forget, they saw the car in two places, and they will say "Facebook" when they mean a friend's share. Your job is a consistent question, a short list of allowed answers, and a rule for "unknown." This is not legal advice about advertising records. Confirm record-keeping with counsel if your state or group requires specific files.
This article is for GMs, internet directors, and desk managers. It sits next to Marketplace versus website leads and tracing sold units back to listings.
Why Source Capture Habits Beat a Guess in the Jacket
A blank source field gets filled with whatever the last person believed. That belief then becomes next month's channel strategy.
What you are trying to learn
You want a primary source for the conversation that became the visit, with room for a second mention:
- Marketplace listing (this rooftop's ad).
- Dealer website or third-party listing site.
- Walk-in / drive-by / lot.
- Repeat / referral / service drive.
- Other (named).
- Unknown.
You are not trying to build a multi-touch model. You are trying to stop coding everything as "internet."
What a bad source field costs you
- You cannot defend posting labor in a used-car meeting.
- You cannot see whether a segment's deals are walk-ins while Marketplace sits silent (or the reverse).
- You double-count when a BDC logs "web" and a green-pea logs "Facebook" on the same deal.
- You undercount Marketplace when the first message was Messenger and the appointment was written as a phone-up.
Asking buyers where they found you is cheaper than those mistakes. It takes one sentence in the first reply and one sentence at the desk.
Honesty about messy answers
Shoppers often:
- Saw the unit on Marketplace, then searched the VIN on your site.
- Saw a friend's share, not your listing.
- Think "Facebook" means the dealership page, a group, or Marketplace.
- Do not remember.
Log what they said. Do not "clean it up" into the channel you wish you had. Unknown is a valid source. Fiction is not.
When and How to Ask Buyers Where They Found You
Timing and wording decide whether you get an answer.
Ask twice: first message and desk, with different jobs
In the first Marketplace reply. You are confirming the listing and opening a visit. A light question belongs after you answer their question, not instead of it:
- They asked if it is available. You confirm, offer a time, then: "Were you looking at this one on Marketplace?"
- If they already said "I saw your listing," you do not need a quiz. Tag Marketplace and move to the appointment.
Do not delay the visit for a form. Source capture that costs the appointment is a failed habit. First-reply craft still follows is this still available scripts.
At the desk or greeter. When they arrive, one line: "How did you find this vehicle today?" Offer examples only if they stall: Marketplace, our website, driving by, a friend.
Write both answers if they differ. Primary = what started the conversation if you have a thread. If they walked in with no thread, primary = what they say at the desk.
Allowed values, not free text chaos
Free text becomes "fb," "face book," "market place," "the gram," and "online." Give reps a pick list that matches how you actually sell:
- Facebook Marketplace
- Facebook (page, profile, or group — only if you truly post there and they said so)
- Website
- Third-party listing (name it if they can)
- Walk-in / drive-by
- Referral / repeat
- Unknown
If your store does not post to groups, do not offer groups as a choice just to feel complete.
Who is allowed to overwrite the field
Rule: the first logged source stands unless a manager is correcting a clear error (wrong VIN, obvious walk-in with no digital trail). Reps may not "fix" Marketplace to website because the buyer later filled a form. Add a second-touch note instead. Double-counting two primaries is how every department claims the same deal.
Log It So the Number Survives the Month
A question without a field is theater.
Minimum record
For every retail deal, and ideally for every appointment:
| Field | Rule |
|---|---|
| VIN | The unit they came to see, even if they buy another |
| Primary source | Pick list, including Unknown |
| Secondary source | Optional, pick list or short note |
| Marketplace thread? | Yes / no |
| Who asked | Initials |
| When asked | First message, arrival, or both |
If they buy a different unit, keep the original VIN as "came to see" and the sold VIN as the deal. That is how you later trace sold units to listings without pretending the Corolla listing sold the Civic.
Where the record lives
Pick one system of record for source. If the DMS has a source field, use it and train the exact pick list. If the DMS source list is a junk drawer, keep a side log that management actually reviews, then map it at month end. Two conflicting systems with no owner is how "internet" wins again.
Managers who already collect Marketplace messages in one place have a head start: the thread itself is evidence of Marketplace as primary, even when the buyer shrugs at the desk. A leads inbox does not replace the jacket field, but it stops the "we have no idea if they messaged" argument.
Monthly hygiene
- Share of deals with Unknown. If that share is huge, the habit is not happening, not "buyers won't say."
- Share coded Marketplace that have no thread. That is a training issue.
- Share of Marketplace threads that never got a source tag because the appointment was written as a phone-up.
Put those three lines on the monthly Marketplace scorecard. Source capture is a process metric before it is a channel metric.
Use Source Capture Without Turning It Into a Weapon
The point is better decisions, not a war between BDC and the floor.
Decisions it should support
- Whether posting labor is connected to visits at all.
- Which segments produce Marketplace conversations versus lot traffic.
- Whether a silent Marketplace week is a logging failure or a true quiet week.
- Coaching: reps who never ask will have mysterious "walk-ins" that started in Messenger.
Decisions it should not support
- Firing a channel based on one month of sloppy tags.
- Paying spiffs on self-reported source without a thread or form to match.
- Publishing a "Marketplace ROI" number you cannot defend. You did not get a controlled study. You got a pick list.
If leadership wants a channel story, give them counts with definitions: deals with Marketplace as primary and a thread, deals with website as primary and a form, deals unknown. Unknown remaining large is itself the story.
Scripts that stay short
Keep language human:
- "Glad you reached out — did you see this one on Marketplace?"
- "When you pulled in, had you already been looking at this car online, or were you driving by?"
- If they name two places: "Which one did you see first?" Log first as primary, second as secondary.
No clipboard. No "for our survey." No interrogation while they are trying to test-drive.
How PostToMarket Automates This
Asking buyers where they found you still requires a human sentence. What software can do is keep the listing, the inquiry, and the sold status on the same VIN so the answer has somewhere to live besides a sticky note.
PostToMarket inventory statuses (draft, posting, posted, sold, failed) tell you which units were actually live when the buyer says they "saw it on Marketplace." The leads inbox gives managers a thread to match against the jacket instead of trusting a guess. Team analytics by rep and source show posting activity; they are not a substitute for buyer-stated source, and you should not treat them as one. Per-rep queues and manager assignment make it obvious who was supposed to ask and reply. Mark as sold and archive so a buyer is not messaging a dead ad you then mis-tag as demand. Unlimited vehicles and bulk import keep the pack in one place so source notes are not split across spreadsheets. AutoPost paces listings one at a time with human-like delays and server-enforced limits, which reduces the chaos of burst posting that makes "which ad did they see?" impossible to reconstruct. PostToMarket is not affiliated with Meta and does not attribute sales on Facebook's behalf.
Stop Coding Every Deal as Internet
If the jacket says "internet" and the meeting still cannot say whether Marketplace earned the visit, you do not have a channel problem yet. Asking buyers where they found you is the source capture habit that replaces the guess. Ask once in the thread, ask once at the desk, log Unknown when that is the truth.
PostToMarket gives you inventory, queues, a leads inbox, analytics, AI listing copy, and AutoPost, with Starter at $59 per month (solo seller, 1 login) and Dealership at $299 per month (up to 13 logins).
