Dealer Group Website Provider Market Share

A dealer group's website platform is the most visible technology decision they make. It shapes everything from inventory merchandising to SEO performance to the digital retailing experience customers encounter before they ever set foot in a showroom. Unlike the DMS, which lives in the back office, the website is customer-facing. Get it wrong, and the revenue impact is immediate and measurable.

The State of Automotive's DealerGroupTechStack database tracks 95 dealer groups with website provider entries, and the findings paint a clear picture: this is a two-horse race, with DealerOn and Dealer.com splitting nearly the entire group-level market. But the real story is in how groups use them — and how the dual-provider reality mirrors the dual-DMS pattern we see across the industry.

The Numbers: DealerOn Leads with 60% Share

Among the 95 groups with website data, DealerOn serves 57 groups (60.0%) and Dealer.com serves 38 groups (40.0%). Those are the only two website providers that appear in the group-level dataset. No Dealer Inspire (Cars Commerce), no DealerFire (Solera), no Sincro (Ansira). At the group level, it's DealerOn and Dealer.com, and that's the entire market.

DealerOn's 60% share is particularly striking because it represents a reversal of the single-point store dynamic. At the individual dealership level, Dealer.com has historically been the market share leader by a wide margin, powered by the Cox Automotive ecosystem — Autotrader syndication, Kelley Blue Book integration, VinSolutions CRM connectivity. But at the group level, DealerOn has pulled ahead.

Why? The answer seems to lie in group-level management capabilities. DealerOn has invested heavily in centralized inventory feeds, multi-rooftop content management, and flexible design tools that let groups maintain brand consistency across dozens of stores while giving each rooftop enough autonomy to compete locally. For a group with 30 stores spread across three states, DealerOn's centralized control with distributed flexibility is a compelling pitch.

The Dual-Provider Reality

Just as 23% of groups run dual DMS platforms, many large groups run both DealerOn and Dealer.com across their rooftops. Morgan Automotive Group (45 rooftops) uses both providers. So does Ourisman Automotive Group (38 rooftops) , David Wilson Automotive Group (21 rooftops) , and Ciocca Automotive (20 rooftops) .

This dual-provider pattern has the same root cause as dual DMS: acquisition. When a group buys a store with a Dealer.com website, they don't immediately rip it out and replace it. Website migrations are expensive in ways that go beyond the vendor contract. A dealership website accumulates years of SEO equity — domain authority, backlinks, local search rankings, Google Business Profile connections. Migrating to a new platform means risking that accumulated equity, even with proper 301 redirects and migration planning.

Domain history adds another layer of complexity. Many dealerships have operated under the same domain for 15-20 years. That domain has aged, accumulated trust signals, and built a backlink profile that a new domain would take years to replicate. When a group acquires a store with a Dealer.com site on a 15-year-old domain, the cost-benefit analysis of migration looks very different than it does for a new open-point store.

The practical result is that groups end up managing two website platforms, two content management systems, two sets of vendor relationships, and two sets of SEO reporting. It's operationally inefficient, but the SEO risk of consolidation keeps many groups in the dual-provider pattern for years.

DealerOn's Mid-Market Advantage

DealerOn's lead is most pronounced in the mid-market — privately held groups with 10-60 rooftops. These groups are exactly the ones with the richest tech stack data in the database, and they're choosing DealerOn over Dealer.com at a roughly 3:2 ratio.

The mid-market dynamic favors DealerOn for several reasons. First, these groups tend to be more design-conscious than the publics. They see their website as a brand asset, not just an inventory display tool, and DealerOn's design flexibility appeals to that sensibility. Second, DealerOn has built a reputation for responsive account management at the group level — dedicated teams that understand multi-rooftop operations rather than a pool of support reps who treat each store as an isolated account.

Third, and perhaps most importantly, independent groups value vendor independence. DealerOn is an independent company. Dealer.com is Cox Automotive, which also owns Autotrader, Kelley Blue Book, VinSolutions, vAuto, Xtime, and a dozen other products. For a group that's trying to avoid vendor lock-in, DealerOn offers a website platform that doesn't come with an entire ecosystem of related products attached.

Dealer.com's Cox Ecosystem Advantage

That said, Dealer.com's 40% share is nothing to dismiss. For groups already deep in the Cox Automotive ecosystem — running VinSolutions CRM, using vAuto for inventory management, listing on Autotrader — Dealer.com is the natural website choice. The integrations are tighter, the data flows are more seamless, and the combined contract leverage can produce meaningful discounts.

Dealer.com also benefits from a massive support organization that smaller website providers can't match. When a group with 40 rooftops has a website issue at 10 PM on a Saturday, Dealer.com has the infrastructure to handle it. That enterprise-grade reliability matters at the group level in ways it might not at a single-point store.

The Cox ecosystem effect is particularly visible in groups that run VinSolutions CRM. VinSolutions integrates natively with Dealer.com websites, creating a lead-to-showroom data flow that's harder to replicate with a DealerOn site. For groups that have standardized on VinSolutions (38 groups in the database, the most of any CRM), Dealer.com becomes the path of least resistance.

The Providers That Don't Appear

Equally telling is who doesn't show up in the group-level data. Dealer Inspire, acquired by Cars Commerce in 2022, serves thousands of individual dealerships but doesn't appear as a primary website provider for any tracked group. DealerFire, owned by Solera, is in a similar position — strong at the single-point level, invisible at the group level. Sincro, the Ansira-owned platform that resulted from the merger of CDK Global's digital marketing business with Ansira's agency services, also doesn't appear.

These providers may well serve groups that aren't yet tracked in the database. But their absence from 95 tracked groups suggests a real structural difference: the capabilities that win single-point deals (price, local support, OEM relationships) aren't the same capabilities that win group-level RFPs (centralized management, multi-rooftop SEO, brand consistency tools).

What This Means for Dealer Groups

For a dealer group evaluating website providers, the data suggests a few practical takeaways.

First, DealerOn and Dealer.com are both viable at the group level. You're not taking a risk by choosing either one — 95 groups have already validated both platforms at scale. The decision comes down to ecosystem fit (are you a Cox shop or an independent shop?), design requirements (how much flexibility do you need?), and the integration layer (how well does the website talk to your CRM and DMS?).

Second, if you're currently running dual website providers, you're in good company. Morgan, Ourisman, and David Wilson all manage the same complexity you're dealing with. The question isn't whether dual providers are ideal — they're not — it's whether the SEO and operational risk of consolidation justifies the efficiency gains. The answer varies by group, and the data suggests many groups decide the answer is "not yet."

Third, the website decision doesn't exist in isolation. It's one node in a technology stack that includes DMS, CRM, inventory management, equity mining, and digital retailing. The best website platform for your group is the one that integrates most cleanly with the rest of your stack — and for most groups in the database, that means thinking about the website, CRM, and DMS layers together, not separately.
