For marketplaces
More buyers for your car listings
CarRadar shows used cars from marketplaces across the region in one search and sends every click to the ad on your own site. We never host the full listing, never take seller contact details and never compete with you for sellers.
Joining CarRadar as a partner is free.
How it works
- Publish one file with all of your active car ads at a stable https address, and regenerate it at least once a day.
- Check the file with the validator below. It reads your feed exactly the way our daily import does.
- Send us the address. We fetch it every day; a car that is no longer in the file is treated as sold or removed.
How to join
- Apply with the form below. It takes a minute and needs no account.
- Your feed is checked automatically the moment you apply, and we receive your application.
- We review it. If you sent your own export instead of the CarRadar format, we map its fields on our side.
- We run a test import. Nothing is shown publicly at this stage.
- We approve your feed. Every listing then appears in CarRadar search under your country, next to the other marketplaces, and links to the ad on your site.
- From then on we fetch your feed every day and you follow your clicks on your partner page.
The format
An XML file with one <ad> element per car inside a <carradar> root. CSV with the same column names, and JSON with an "ads" array, are accepted too. Already have an export in another shape? Send it anyway: we map the fields on our side.

Good to know
- Every ad needs a link back to your site. That link is where every click goes.
- Send the whole inventory every time. An ad that disappears from the file is treated as gone.
- Values are case insensitive. Unknown values are stored as empty, never guessed.
- Only the first photo is used, as a preview. We never copy or host your images.
Check your feed
Paste the address of your feed. Nothing is stored or published by a check.
What we count, and how you can check it
- Every click from CarRadar to one of your ads is counted on our server.
- Clicks from bots, link previews and repeat clicks by the same visitor within an hour are recorded but not counted.
- Each link to your site carries utm_source=carradar, utm_medium=referral and utm_campaign=partner_feed, so the visits show up in your own analytics.
- Each link also carries a crclid parameter, a unique id per click. You can match it against our report on your side.
- We never store a visitor's IP address, only a short-lived anonymous fingerprint used to filter repeat clicks.

After approval, sign in to CarRadar with the email address you applied with and open your partner page. It shows clicks per day, your most clicked listings, how many listings are live and the result of your latest import.
