How do car marketplaces get more sellers to list?
By Bogdan Ladaru · Co-founder & CEO · Updated Sep 13, 2026
Short answer
Car marketplaces get more listings by marketing to the short side of the market on purpose: video that shows a listing being published rather than described, ads timed to the moment people decide to sell, a listing path stripped to what a listing actually needs, and seller sign-ups tracked as their own conversion.
A marketplace runs on liquidity. Buyers come for choice, sellers come for buyers, and whichever side is short sets the ceiling for both. Most campaigns chase the side that is cheaper to reach, which is rarely the side holding growth back.
The playbook
- 01
Find the short side, in numbers
Listings published and buyer enquiries, week by week, plus how many listings get no enquiry and how many searches end with nothing worth viewing. Count before you spend: the answer decides who the campaigns talk to.
- 02
Show listing being done, not described
Short vertical video of a real listing going up — photos, price, publish — answers the only question a seller has: how long will this take me. It travels further than any promise about the platform.
- 03
Reach sellers at the moment they decide
Search ads on the terms people use when they want to sell, and campaigns around the moments that produce listings: an upgrade, a move, a second car standing unused.
- 04
Cut the path to a live listing
Every extra field costs listings. Ask only for what makes a listing findable, fill what you can from the registration or the VIN, and let a seller finish on a phone in one sitting.
- 05
Make the first listing work
A seller whose first listing brings enquiries comes back with the next car. Guidance on photos, a realistic price range from your own data and a nudge when a listing goes stale are supply-side marketing.
- 06
Measure the two sides apart
Seller sign-ups and published listings as conversions of their own, separate from buyer enquiries. Measured together, the cheaper side eats the budget and the short side stays short.
At a glance
Which side is short, and what it changes
| What you see | Which side is short | Where the budget goes |
|---|---|---|
| Listings sit with views but few enquiries | Buyers | Demand campaigns on the categories those listings are in |
| Buyers search and find little worth viewing | Listings | Seller campaigns and an easier listing path |
| Sellers start a listing and abandon it | Neither: the flow is the problem | Fixing the flow before buying more traffic |
| Listings come in but sell slowly | Buyers in that segment | Category-level demand, not more sellers |
| One region performs, the others do not | Liquidity is local | Region by region, on the side that is short there |
Proof
For Direktcar, a car marketplace, we built a content engine of reels and shorts engineered for distribution, with consistent viral hits, working the top and middle of the funnel. For PIX Moving, an autonomous mobility company, we run the paid B2B campaign for the Paris Motor Show 2026.

Related questions
Which side of the marketplace should we market to first?
The short one. If buyers arrive and find nothing worth viewing, more buyer traffic makes the problem visible faster; it does not fix it.
Do we need paid ads if the content already performs?
They do different jobs. Content builds the base of people who know the platform; search ads reach the person who decided to sell today. Judge them on listings, separately.
How do we know a campaign produced listings and not just visits?
Make the published listing a conversion in its own right, keep the campaign tags and the click ID with the seller account, and report cost per published listing next to cost per buyer enquiry.
