DealerSignals Tech Adoption Index — Methodology

Methodology version 1.0 · Baseline scan: May 2026 · Coverage: 1,760 U.S. dealerships across 40 states

The DealerSignals Tech Adoption Index (DTAI) is a quarterly measurement of how much technology U.S. auto dealerships actually run. It is built entirely from programmatic scans of dealers’ public web presence — measured, not self-reported. This page documents exactly how the Index is constructed, so any figure we publish can be understood, scrutinized, and cited with confidence.

What the Index measures

We organize dealer retail technology into 15 measured categories. For every dealer, we determine which of those categories the dealer runs at least one tool in. The count of categories a dealer runs is its Stack Depth, and the headline Index value is the average Stack Depth across all dealers measured.

DTAI (May 2026 baseline): the average U.S. dealer runs 3.8 of 15 measured technology categories.

Stack Depth was chosen as the headline metric because it is directly measured, requires no subjective weighting, and moves cleanly over time — making quarter-to-quarter change easy to read and hard to dispute.

The 15 measured categories

Category	What it captures
Website & Digital Marketing	The dealer’s website platform/CMS and integrated digital-marketing tooling

Inventory Management	Inventory, merchandising, and vehicle-data tools
Reputation Management	Review and reputation platforms
Paid Advertising & Attribution	Managed paid-media and attribution platforms
Chat & Messaging	Website chat, text, and messaging tools
Trade-In & Valuation	Trade-in and vehicle-valuation tools
CRM Platforms	Customer relationship management systems
F&I Platforms	Finance & insurance and online finance tools
DMS Platforms	Dealer management systems
Data & Analytics Tools	Analytics, reporting, and data platforms
Fixed Ops Software	Service, parts, and fixed-operations tools
Online Deal Tools	Digital-retailing and online deal-building tools
Video & 360° Retailing	Video and 360° vehicle-merchandising tools
In-House Finance	Buy-here-pay-here and in-house payment tools

Two further categories appear in our taxonomy but are excluded from the Index because they are not yet instrumented with detection signatures. A category enters the Index only when it can actually be measured; including categories no dealer can be detected in would understate every dealer’s Stack Depth.

How detection works

For each dealer, our scanner visits the key pages of the dealership site — homepage, inventory/VDP, financing, contact, and trade-in pages — and inspects two kinds of signal:

• HTML signatures — markup, scripts, and embedded references a vendor’s product leaves in the page.
• Network signals — requests the page makes to a vendor’s services as it loads.

A vendor is recorded as present when one or more of its fingerprints matches these signals. Each detection is classified by tier:

• Primary — the dealer is running the vendor’s core product. Only primary detections count toward the Index.
• Infrastructure — generic, near-universal tooling such as ad pixels and general analytics trackers. These are excluded, because counting them would inflate adoption with technology that says little about a dealer’s retail stack.
• Subcomponent — secondary signals rolled up under their parent product and not counted separately.

This distinction matters: counting all detected technology rather than primary-tier only would raise the average Stack Depth to roughly 5.5 and misrepresent genuine adoption. The Index deliberately counts only the technologies a dealer has meaningfully deployed.

Dealer segments

Each dealer is classified into one of three segments, which lets us report Stack Depth by dealer type:

• Franchise — dealers selling new vehicles under one or more OEM franchises.
• Independent — used-vehicle dealers not operating under an OEM franchise.
• Buy-Here-Pay-Here (BHPH) — independent dealers offering in-house financing.

Universe and inclusion

The baseline Index covers 1,760 dealerships across 40 states whose sites scanned successfully in the May 2026 window. A dealer is included when its site returns a successful scan; sites that fail to load or block automated access are excluded from that edition rather than counted as zero, so the Index reflects measurable dealers only. Coverage expands in future editions as the dealer universe grows.

Cadence and versioning

The DTAI is published on a quarterly cadence, with a deeper annual “State of Dealer Technology” report.

This is methodology version 1.0. Any change to the category taxonomy, the detection signatures, or the Stack Depth definition will increment the version number and be disclosed in the affected report. Historical figures are never silently restated. Where a methodology change would alter past numbers, both the prior and revised bases are shown for the overlapping period, so the time series remains honest as it compounds.

Limitations

We state these plainly, because transparency about boundaries is what makes a benchmark trustworthy:

• Presence, not depth of use. The Index detects that a dealer runs a tool, not how extensively or effectively.
• Web-detectable footprint. Technologies with no public web signal — some purely back-office systems — may be undercounted.
• Point-in-time. Each edition reflects its scan window.
• Coverage. The baseline spans 40 states and expands over time.

No figure in the Index is self-reported. Every number derives from the scan.
