Automotive inventory ads Every vehicle the dealer pays for should run.

ÆTHR checks, fills and verifies the inventory data behind your dealers' campaigns. More vehicles pass. Budgets land where the dealer expects.

Dealers budget for 400 vehicles. The catalog runs 340.

Dealers set ad budgets on unit count. Ad platforms only run the vehicles whose data passes. The rest drop out quietly. The money doesn't. It piles onto fewer vehicles, and results slip.

You're getting blamed for data you didn't create.

The dealer can't see the 60 missing vehicles. They just feel results are off. So they switch agencies. The new agency gets the same feed and the same gaps. The data never got fixed.

Why vehicles fall out of automotive inventory ads.

Most drops come down to a handful of fields.

No price.
No photos.
A VIN that's malformed or listed twice.
A trim that doesn't match.
A feed price that doesn't match the website.

On Google vehicle ads, for example, a missing required field can keep a vehicle from showing at all.

Fix the catalog before it ships.

Your campaigns can't be better than the data behind them. So ÆTHR fixes the data first.

Why are my dealers' vehicles dropping out of Facebook and Google inventory ads?–

Ad platforms only run vehicles whose data passes. Most drops come down to a few fields: no price, no photos, a malformed or duplicate VIN, a trim that doesn't match, or a feed price that doesn't match the website. ÆTHR catches these before the catalog goes out and fills missing attributes from OEM build data. More vehicles stay in market.

How long does it take to add a new dealer?+

Under 30 minutes. Your team sets up the dealer in ÆTHR's self-serve interface, and data starts flowing. Catalogs get built and ads can run the same day. You don't email a feed provider or wait on an export.

Can ÆTHR fix wrong VDP links in an inventory feed?+

Yes. ÆTHR maps each vehicle to its correct vehicle detail page before the feed goes out, so ad clicks land on the right dealer page. Then Prism checks the live VDP to confirm the price matches the feed.

How do we show a dealer what's actually running?+

ÆTHR gives you a client report for each dealer. It shows units in inventory, units in market, what was missing, what got fixed and when. Bring it to the next review, and the conversation shifts from "something feels off" to the numbers.

Can we build our own tools on our clients' inventory?+

Yes. Each dealer gives you an API key, and one API returns that dealer's inventory. Build an SEO tool, a model page or a BDC assistant once, then run it for every client. Read the API docs to get started.

Pick one client. We'll show you what's missing.

Thirty minutes. We compare that dealer's inventory with what's reaching market and show you where vehicles drop.
