The OEM Website Problem No One Wants to Talk About (Except Ford)

Over the past several months, I’ve been digging into something that should concern every dealer operating under an OEM-mandated website program:

Mobile performance is being overlooked—and it’s quietly costing dealers traffic, leads, and sales.

This isn’t a theory. It’s showing up directly in the data.

The Reality: Most Dealer Traffic Is Mobile

Today, the majority of dealership website visitors are on mobile devices. They’re:

• Researching vehicles
• Browsing inventory
• Checking pricing
• Scheduling service

Mobile is no longer “secondary”—it’s the primary battleground.

And yet, many OEM-approved website platforms are still not optimized for real-world mobile performance.

A Real Example: When “Passing Core Web Vitals” Isn’t Enough

Let’s look at a real-world case.

A dealership website running on a major OEM-approved platform shows the following Google PageSpeed Insights mobile metrics:

OEM Platform Site (Honda Dealer Example)

• Performance Score: 29
• First Contentful Paint (FCP): 3.9 seconds
• Largest Contentful Paint (LCP): 14.4 seconds
• Total Blocking Time (TBT): 2,510 ms
• Speed Index: 16.1 seconds
• Total Page Size: 5+ MB

Yes—the site technically passes Core Web Vitals based on field data.

But the simulated experience tells the truth:

The site takes over 14 seconds to fully render meaningful content
The browser is blocked for 2.5 seconds before users can interact
The page is heavy, script-loaded, and slow to respond

This is the experience real customers are dealing with—especially on average mobile connections.

Now Compare That to a Competitor

Here’s a competing dealership site:

Competing Ford Dealer Website

• Performance Score: 75
• Largest Contentful Paint (LCP): 1.5 seconds
• First Contentful Paint (FCP): 1.1 seconds
• Interaction to Next Paint (INP): 88 ms
• Time to First Byte (TTFB): 0.7 seconds
• Cumulative Layout Shift (CLS): 0.04

This site loads quickly, responds instantly, and delivers a smooth experience.

That’s not just a technical difference—that’s a competitive advantage.

Why This Matters More Than Most Dealers Realize

The gap between a performance score of 29 and 75 is massive—and it directly impacts:

• Bounce rates (slow sites lose users immediately)
• SEO rankings (Google prioritizes fast, usable pages)
• Paid traffic ROI (you’re paying for clicks that never convert)
• Lead volume (form fills, calls, chat engagement)
• Customer perception of your dealership

In simple terms:

You can’t out-market a slow website.

The Root of the Problem

PageSpeed Insights highlights the usual culprits:

• Heavy third-party scripts
• Render-blocking resources
• Large JavaScript execution times
• Inefficient caching
• Excessive network payloads
• Main-thread blocking

But here’s the bigger issue:

Dealers often don’t control these elements.

They’re bundled into OEM-approved platforms:

• Digital retail tools
• Chat providers
• Accessibility overlays
• Analytics and tracking scripts
• Inventory systems

Each one adds weight.
Each one adds delay.

And collectively—they’re crushing mobile performance.

The OEM Constraint Problem

Many OEM programs require dealers to choose from a limited list of approved website providers.

In theory, this creates standardization.

In practice, it creates a problem:

Dealers are accountable for performance
But don’t control the platform
And vendors aren’t being measured aggressively on mobile speed

So performance becomes… nobody’s responsibility.

Why Ford Stands Out

Ford has made noticeable progress in pushing performance and modernization across its digital ecosystem.

Not perfect—but directionally aligned with where things need to go:

• Faster sites
• Better UX consistency
• More attention to performance

That raises an important question:

Why isn’t every OEM making mobile performance a top priority?

What Needs to Change

This isn’t about blaming vendors—it’s about aligning incentives.

If OEMs want dealers to compete effectively online, mobile performance needs to become a core requirement, not an afterthought.

Here’s what that could look like:

1. Establish Minimum Mobile Performance Standards

• LCP under 2.5 seconds
• Performance scores consistently above 70
• Strict limits on total page weight

2. Audit Approved Vendors Using Real Data

• Use PageSpeed Insights and CrUX data
• Compare vendors side-by-side
• Remove or flag underperforming platforms

3. Reduce Default Script Bloat

• Defer non-essential tools
• Load features on user interaction
• Eliminate redundant third-party scripts

4. Give Dealers More Control

• Ability to disable non-critical features
• Transparency into what scripts are loading
• Flexibility in optimization strategies

The Bottom Line

Dealers are investing heavily in:

• Paid search
• SEO
• Third-party leads
• Social and display campaigns

But if the destination—the website—is slow on mobile, that investment is leaking at the worst possible point.

This isn’t a minor technical issue.

It’s a competitive disadvantage.

And it’s one the industry can—and should—fix.

Final Thought

The goal is simple:

Give customers a fast, responsive, professional experience that reflects the quality of the brand.

Right now, too many OEM website ecosystems are falling short of that standard.

And the longer it goes unaddressed, the more ground dealers lose to competitors who simply load faster.

At one point, I escalated these concerns directly to an OEM.

The response?

Mobile performance wasn’t their problem.
And I was told—very clearly—not to tell them how to run their program.

Let’s be honest about what that means.

Dealers are required to operate within OEM-approved website ecosystems.
We don’t pick freely—we choose from a controlled list.

At the same time, we’re held accountable for:

• Lead volume
• Conversion rates
• Customer experience
• Digital performance

But when the platform underperforms?

“Not our problem.”

You Can’t Have It Both Ways​

If OEMs:

• Control the ecosystem
• Approve the vendors
• Require the tools

Then performance is part of that responsibility.

You can’t lock dealers into a system and step back when that system doesn’t compete.

That’s not a partnership—that’s a constraint.

The Real Cost of Ignoring This​

Every slow-loading mobile page creates friction:

• Shoppers bounce before inventory loads
• Paid clicks never turn into opportunities
• Service customers abandon scheduling
• Competitors win without spending more—just by being faster

Dealers don’t feel this as a “technical issue.”

We feel it in:

• Missed leads
• Lower closing ratios
• Wasted ad spend

The Hard Truth​

Right now, in many OEM programs, performance isn’t owned by anyone:

• Vendors say it’s the OEM structure
• OEMs say it’s the vendor
• Dealers are left holding the results

That’s the problem.

If a dealer is required to use an OEM-approved platform…​

Then the OEM is already in the website business—whether they want to admit it or not.

And if that website doesn’t perform on mobile,
it’s not just a vendor issue. It’s a competitive failure.
