The Inventory Feed Audit • Specialty 9 of 14
Your inventory feed runs to a dozen destinations. Most dealers have never validated that any of them are receiving complete, current data.
We audit every feed your site emits: Google Vehicle Listings, Facebook Catalog, Cars.com, AutoTrader, CarGurus, Bing, and your OEM. We tell you which units are missing, which fields are malformed, and which destinations have not received an update in days.
What a broken feed is costing you
Every unit not in a destination feed is a unit those shoppers cannot see. On Google Vehicle Listings alone, a missing VDP loses an entire channel of free, high-intent traffic.
Inventory feeds are the silent backbone of dealer marketing. Google Vehicle Listings, Meta automotive ads, third-party listings sites, and OEM tier-3 programs all consume the feed your platform emits. When the feed is incomplete, malformed, or stale, you do not get an error message. You get fewer impressions, fewer leads, and less attribution to figure out why.
On the typical dealer site we audit, between 8 and 22 percent of active inventory is missing from at least one major destination at any given time. Feed problems are the most fixable channel-loss problem in dealer marketing and the least diagnosed.
Estimate the cost of feed gaps across destinations.
Estimated units missing from a major feed
45 units
Estimated units invisible on at least one major destination. Directional lost-lead estimate at industry averages: ~27 leads/mo across all channels combined.
What nobody has told you
"Your platform emits the feed. Your platform does not validate that the destinations accepted it. Nobody in your default supplier chain owns the round trip."
"Google Merchant Center for Vehicle Listings will silently disapprove units for missing fields, image issues, or policy violations. The disapprovals appear in a dashboard most dealers do not have access to."
"Facebook Catalog requires a different schema than Google. Most dealer platforms emit one feed and try to make it work for both. Some units make it. Some do not."
"After every platform update, every OEM template change, and every migration, the feed format can shift slightly. Destinations either accept the new format or quietly drop units. The dealer is the last to know."
The five failures we find on almost every dealer site
On most dealer sites in this area, you almost certainly have at least three of these.
Google Vehicle Listings feed disconnected or stale
Google Vehicle Listings is a free, high-intent inventory placement on Google Search. The feed must be set up in Google Merchant Center and refreshed daily. We find disconnected or 7+-day-stale feeds on a meaningful share of audited dealers.
How we fix it: Re-establish Merchant Center connection. Configure daily fetch. Verify last-fetched date and disapproval count.
Required fields missing or malformed
VIN, year, make, model, trim, mileage, price, photos, vehicle URL, dealer location. If any required field is missing or malformed, the unit is rejected by the destination. Dealer photos at low resolution are a common silent disapproval.
How we fix it: Field-by-field validation. Missing field remediation at the source. Image resolution audit (1024x768 minimum recommended).
Feed pointing to old URLs after migration
After a website migration, the feed often continues to emit URLs from the old site. Destinations crawl them, find 404s or redirects, and drop the units. Recovery takes weeks even after the URL is fixed.
How we fix it: Audit feed URL structure after every platform change. Verify destinations resolve final URLs cleanly. Re-submit on URL pattern changes.
Sold inventory persisting in feed
VDPs for sold vehicles continue to emit in the feed for hours or days after sale. Destinations show out-of-stock units. Shoppers click through to a 'no longer available' page. Trust drops, CTR drops, future impressions drop.
How we fix it: Real-time or hourly feed regeneration on sale. Implement availability=out_of_stock signal where supported. Same-day URL handling.
Facebook Catalog mismatch
Facebook automotive catalog uses a different schema than Google. Many dealer feeds attempt to serve both with one file. Some fields map cleanly. Many do not. Result: a partial catalog on Facebook, missing units in dynamic ads.
How we fix it: Generate destination-specific feeds. Validate via Facebook Commerce Manager. Address category mapping issues.
Image issues silently rejecting units
Watermarks, logos overlaid on the photo, dealer-branding bars, low resolution, stock photos for in-stock units. Each can trigger silent disapproval at Google Merchant Center.
How we fix it: Image policy audit. Watermark removal where required. Resolution and aspect-ratio validation.
Pricing inconsistencies across destinations
VDP price, feed price, and Google Merchant Center price disagree. Shoppers see one price, click, find another. Trust signal drops. Some destinations penalize price-mismatch with reduced visibility.
How we fix it: Cross-destination price validation. Source-of-truth designation. Daily reconciliation report.

What happens when you fix it
Fixing this is not a website redesign. It is a series of specific, surgical changes.
01
DIAGNOSIS
We give you the report
48 hours. Every finding, ranked by impact and effort, with platform-specific instructions for your CMS. You can hand it to your web vendor and they can implement most of it.
02
IMPLEMENTATION (OPTIONAL)
We do the work
If your vendor cannot or will not, we install the fixes ourselves. Most live in Google Tag Manager, the head of the page, or as a CDN-level configuration. Live in 7 to 14 days.
03
VERIFICATION
We re-run the scan
30 days after the fixes go live, we re-run the audit and confirm the lift. Site Health Score increase, category-level pass, downstream impact verified.
What the data says.
8–22%
of active inventory is typically missing from at least one major destination on any given day for dealers we audit.
Free
Google Vehicle Listings is a no-cost organic placement. Most dealers have never properly enabled it.
1 feed, many destinations
Google, Facebook, Bing, Cars.com, AutoTrader, CarGurus, TrueCar, OEM tier-3. Each consumes the feed differently. Most dealers validate none of them.
What a clean feed unlocks
A Chevy store recovered $48k in monthly first-party leads after a feed remediation.
A Chevrolet dealer was losing roughly 18 percent of monthly leads year-over-year and could not pin down the cause. Ad spend was flat, on-site conversion was steady, organic traffic was unchanged. We audited the inventory feeds.
Google Merchant Center had not received a fresh feed in 11 days due to a credential expiration nobody had noticed. Facebook Catalog was rejecting 34 units for image policy violations dating back two months. Cars.com was missing 22 units due to a VIN-format change after a recent platform update.
We re-credentialed Merchant Center, fixed the image policy issues, and aligned the VIN format to Cars.com requirements. Within 14 days, total feed-driven impressions across destinations recovered to baseline. Within 30 days, the missing 18 percent of monthly leads had returned. Estimated value of recovered leads: $48,000.

Inventory Feed Audit-specific questions dealers ask.
Answered straight.
What is the difference between a feed and a sitemap?
A sitemap tells Google organic search what URLs exist on your site. A feed tells specific destinations (Google Vehicle Listings, Facebook Catalog, third-party sites) what inventory units exist with structured data. Different files, different consumers, different problems.
Is Google Vehicle Listings the same as Google Ads inventory?
No. Google Vehicle Listings is a free organic placement on Google Search. Google Ads Vehicle Inventory Ads (VIA) is the paid version. Most dealers should run both. The feed audit covers both.
Who controls the feed?
Your dealer platform generates the source feed. The destinations consume it. Some destinations require additional setup (Merchant Center, Commerce Manager). The feed audit covers the entire round trip.
Can you fix the feed without changing platforms?
Most issues. Field-completeness, image issues, sold-inventory persistence, destination credentials, schema mismatches. Some issues are platform-architectural and require platform-side changes.
What about my OEM tier-3 program?
OEM-mandated programs (Toyota Smart Path, Ford Direct Inventory, Honda Marketplace, etc.) consume your feed differently. We audit OEM-program-specific feed compliance as part of the engagement when applicable.
How often should the feed refresh?
Daily minimum for most destinations. Hourly or real-time for the highest-velocity destinations (Google Vehicle Listings, Facebook). Some destinations cap how often they will accept updates.
Does this work with my third-party feed manager (HomeNet, vAuto, Dealertrack)?
Yes. Third-party feed managers add another layer to validate. We audit the chain from inventory source through manager through destination.
How long does the free scan take?
Thirty seconds for the public-feed sample. Full destination audit inside 5 days after you grant access to the relevant accounts.
