LGG Media builds exclusive subprime auto leads on Google Ads for BHPH dealers and automotive finance groups spending $30,000 or more per month per rooftop. Underwriting-tier values flow back to the bidding algorithm, so budget finds borrowers who fund and keep paying, not form fills that never finance.
A BHPH dealer earns twice on every delivery: the vehicle sale and the financing. A Tier 1 borrower generates 36 months of loan payments; a Tier 4 borrower who defaults early erases the profit on both. Yet standard special finance leads and BHPH marketing optimize cost per form submission, a metric that treats a 450 credit score identically to a 650, so volume goals quietly backfire on loan performance. The dealer network in our case study came to us with exactly that problem.
The difference is not lead quality, it is what the ad platform gets to learn from. A vendor reselling applicants across competing lots can only ever optimize on the shallowest signals. In-house infrastructure feeds the deep ones.
A form fill scored as marketing-qualified by the answers in it. An inbound call, or a call that crosses a duration threshold. That is the entire list, and the vendor’s algorithm optimizes it across every dealer it sells into, never on whether a loan funded or performed.
Qualified applications. Tier-weighted value at pre-approval or delivery. Sixty-day portfolio performance folded back into lead scoring. These signals only exist inside your DMS and loan servicing data, and only in-house infrastructure can feed them back to the ad platforms, on your account, for your portfolio only.
Our proprietary tracking architecture ties every application, pre-approval, and delivery back to the originating click, then teaches the algorithm which borrowers actually sustain a portfolio. Four rules make the signal trustworthy:
Value passes dynamically at pre-approval or vehicle delivery, scaled by underwriting tier: Tier 1 prime carries the maximum, deep subprime a lower baseline. Target ROAS then trains toward high-margin, lower-risk borrowers instead of high-volume form fills.
Early payment defaults push negative conversion adjustments inside a 30 to 90 day window, the same mechanism our moving clients use for cancellations. Platforms optimize on the delivery event, but 60-day portfolio performance folds back into lead scoring, so bidding stops over-indexing on high-default segments.
Twenty-one dealer groups run as 21 individual Google Ads accounts under one master MCC. Conversion definitions and dynamic values are standardized at the MCC level, so training is uniform while budgets and local performance never mix.
Subprime buyers travel 15 to 30 miles for purchase and servicing, so every lot runs strict radius targeting. Ad messaging, landing pages, and budget react to real-time lot inventory: when older sedans outnumber SUVs on the ground, campaign structure and keyword priority follow.
Standard BHPH marketing optimizes cost per form submission, and a form fill from a 450 credit score looks exactly like one from a 650. The metric that changes operators is tier-weighted conversion value: the portfolio tier mix of funded loans. Moving Smart Bidding from target CPA on form fills to target ROAS on tier-weighted deliveries trains the account to find applicants who close and keep paying. The operator stops asking how many leads $30 buys and starts asking what share of funded loans came from top-tier borrowers.
Copy constraints are set per dealer, because each group operates under distinct state licenses and underwriting criteria. Inside TILA and FTC boundaries, Guaranteed Approval and $0 Down never run unless the terms are universally available without qualification. Competitors lean on bait-and-switch clickbait, Everyone Approved, $0 Down Today, and buy themselves un-financable lead flow. Refusing deceptive trigger copy protects dealer compliance and filters non-qualifying prospects at the ad level, so spend reaches borrowers who fit each dealer’s underwriting matrix before the first form fill.
An automotive finance platform serving Buy Here Pay Here dealers runs its network’s acquisition on this infrastructure: 21 active dealer groups, $5 million in annual ad spend, 22,000 vehicle deliveries per year at a cost per delivery under $230. The share of high-quality, low-default-risk customers in the portfolio nearly doubled in four years, which is the number the whole methodology exists to move. Tier-weighted bidding is why volume and loan performance rose together instead of trading against each other.
No. Every lead is generated exclusively for one dealer group through its own ad account, with the dealer’s brand on every ad and landing page. Purchased subprime and special finance leads are typically resold across competing lots. An applicant who came through your own ad is already on your lot’s radius, looking at your inventory.
A value scaled by underwriting tier, passed dynamically at pre-approval or vehicle delivery. Tier 1 prime borrowers carry the maximum value and deep subprime carries a lower baseline, so value-based bidding trains toward high-margin, lower-risk borrowers instead of raw form fills. Early payment defaults push negative conversion adjustments within a 30 to 90 day window, and 60-day portfolio performance folds back into lead scoring so bidding never over-indexes on high-default segments.
One account per dealer group under a single master MCC. Conversion definitions and dynamic values are standardized at the MCC level, so the algorithm trains uniformly while budgets and local performance stay fully separated. Each lot runs strict radius targeting, because subprime buyers travel only 15 to 30 miles for purchase and servicing, and campaigns react to real-time lot inventory, so the vehicles on the ground dictate keyword priority.

Tier-weighted conversion value, meaning the portfolio tier mix of funded loans, not cost per form submission. A form-fill metric treats a 450 credit score identically to a 650. Moving bidding from target CPA on form fills to target ROAS on tier-weighted deliveries trains the account to find applicants who close and keep paying. You can only control what you bid on.
$30,000 per month in ad spend per dealer group, month to month, no long-term contract. The network in our case study runs $5 million in annual ad spend across 21 dealer groups at 22,000 vehicle deliveries per year, under $230 per delivery.
