Sentinel grades your full vendor stack in one monthly report — website provider, paid-search agency, and the three lead providers most digital audits ignore. Every row scored. Every finding tracked until close. Every dollar accountable.
This is what your dealer principal sees on the 5th of every month. One page. Five rows. The whole picture.
If you're operating an OEM-franchised dealership at scale, you're probably already paying for multiple audit-flavored products: a website monitor here, a compliance tool there, maybe a CRM lead-quality service somewhere else. Each one tells you one story about one part of your business. Nobody tells you the unified story.
Meanwhile, the highest-risk and highest-waste areas of your digital spend — OEM Tier 3 compliance on every ad you run, FTC disclosure compliance on every offer page, and lead-provider performance across AutoTrader, Cars.com, CarGurus, and the OEM-mandated providers — sit completely unmonitored. You're trusting vendor reports. You're trusting the providers themselves. You're hoping the OEM rep doesn't notice anything during their next regional review.
Sentinel is built to close all of these gaps in one monthly report.
Daily monitoring, Core Web Vitals, GA4 tracking audit, GTM container inventory, inventory feed integrity, AI visibility scan. Same depth as Inspector.
Every active Google, Meta, and Microsoft creative reviewed. Waste detection. Pacing review. Creative compliance pre-check.
Vendor lead-source claims reconciled against CRM ground truth. Tracking platform verification. End-to-end dollar tracing.
Every published offer reviewed against the current Tier 3 guideline document your store supplies at onboarding, alongside federal FTC disclosure standards. Photographic evidence captured. Pre-flagged before your OEM rep sees it. Compliance summary delivered annually for your records.
Every active third-party lead provider in your stack — AutoTrader, Cars.com, CarGurus, OEM-mandated providers — audited for unit economics, lead duplication, conversion rate, and value-per-dollar performance. The data your providers don't put in their own reports.
Plus everything in Auditor: Dual-PDF monthly delivery, vendor scorecard with carryover tracker, daily monitoring & alerts, monthly 30-minute review call, priority email and Slack support, annual compliance summary for your records.
Most audit products cover some version of the website-audit problem. A smaller set go further into ad performance. Sentinel adds the layer that's most likely to result in financial consequence — co-op chargebacks from your OEM, FTC enforcement on bad ad disclosures, regional review failures — and bakes it into the monthly cadence so issues surface before the OEM rep does.
You're already spending real money on AutoTrader, Cars.com, CarGurus, or whatever OEM-mandated lead provider your franchise requires. None of those providers will tell you whether the leads you're paying for are duplicates, what your conversion rate is relative to other providers, or whether you're getting the same unit economics as competing dealers in your zone. Sentinel audits all of that. It's the conversation your providers don't want you to have.
Your website vendor gets a grade. Your ad vendor gets a grade. Your attribution platform gets a grade. Each lead provider gets a grade. Every vendor in your stack ends up on the same monthly scorecard, graded against the same criteria, with the same accountability loop. The conversation in your business reviews stops being separate vendor conversations and starts being one unified vendor performance conversation. That's the kind of leverage you can only build when one independent party is watching all of them at once.
Five audit pillars. Dual-PDF monthly report. Monthly 30-minute review call. Annual compliance summary. Priority support. Same accountability loop. Same no-contract policy.
Pillar 4 (compliance) and Pillar 5 (lead provider) are typically where the largest recoverable spend findings surface — modeled per finding in your report, with confidence tiers attached.
Five pillars. One report. Every vendor in your stack on the same scorecard. Compliance and lead-provider blind spots covered every cycle.
