Low cost per lead is not the goal. Sold vehicles are the goal.
This distinction matters more than most dealers track. A $30 CPL that closes at 4% produces the same number of sales as a $60 CPL that closes at 8% — but costs twice as much. The math only works when CPL and close rate are measured together.
Most BC dealerships know their CPL (or have a rough sense of it). Far fewer track close rate by lead source. That's where most of the optimization opportunity hides.
Industry Benchmarks: Close Rate by Lead Source
The most current benchmarks for internet lead close rates come from Cox Automotive, NADA, and DealerSocket's annual reports. Numbers vary by market, price point, and follow-up quality — but here are the ranges BC dealerships should be working from in 2026:
| Lead Source | Industry Average Close Rate | Top-Quartile Dealers |
|---|---|---|
| Google Search Ads | 10–15% | 18–22% |
| Facebook/Instagram Ads | 5–9% | 12–15% |
| Facebook Marketplace | 10–14% | 16–20% |
| Third-Party Leads (AutoTrader, Cars.com) | 3–6% | 8–10% |
| Website Organic/Direct | 12–18% | 20–25% |
| Phone-In Leads | 20–30% | 35%+ |

Google leads close highest among paid digital sources because they reflect active purchase intent — someone searched "2026 RAV4 BC dealership" and clicked your ad. They're comparison shopping, but they're ready to buy.
Facebook Ads close lower, not because the leads are bad, but because the funnel is different. Facebook interrupts people who weren't actively searching. The conversion window is longer and the lead needs more nurturing. Treating a Facebook lead with the same urgency as a Google lead — and then wondering why it doesn't close as fast — is a common mistake.
Marketplace closes similarly to Google because it also captures active intent. Someone browsing Marketplace already knows they want a car.
Third-party leads close the lowest. This has been consistent for years. AutoTrader and Cars.com shoppers are comparison-shopping across many dealers simultaneously. You're one of 8–12 options they're looking at. Speed and differentiation matter enormously.
What Counts as an Internet Lead (Get This Right First)
Before benchmarking your close rate, make sure you're measuring the right thing. A "lead" should be:
- A new contact with verifiable purchase intent (name, phone number, and/or email)
- Generated by your digital marketing (not service customers calling the main line)
- From someone who isn't already in your CRM as an active deal
If your BDC is logging every phone call as a lead — including vendors, misdials, and service inquiries — your lead count is inflated and your close rate will look artificially low.
Clean up the definition before comparing your numbers to industry benchmarks. Comparing a dirty lead count to NADA's cleaned data is how dealerships convince themselves they're underperforming when they're actually tracking wrong.
Why Google Leads Close Higher Than Facebook Leads
This isn't just about intent — it's about where the buyer is in their journey.
The average Google Search lead has been researching for 2–3 weeks and has narrowed to a shortlist. They're searching for specific models, comparing trim levels, and ready to price. When they click your Google ad, they have specific questions.
The average Facebook lead discovered your dealership from a News Feed ad. They're earlier in the journey — often triggered by a creative that caught their attention rather than active research. They need more touchpoints before they're ready to commit.
Implication for your BDC: Google leads warrant same-day, same-hour response. Facebook leads warrant a longer, multi-touch nurture sequence. Treating both with the same 3-call follow-up protocol mismatches the sales motion to the lead quality.

BDC Close Rate vs. Sales Floor Close Rate
There's an important distinction between how a BDC closes and how the floor closes — and most dealerships conflate the two.
The BDC's job is to convert a lead to an appointment. BDC close rate is really appointment-set rate. Industry benchmark: 40–60% of qualified internet leads should set an appointment with good BDC process.
The sales floor's job is to convert the appointment to a sale. Appointment-to-sale rate is typically 50–70% at well-run stores — meaning if 10 people come in, 5–7 should buy.
Blended internet lead close rate (lead → sale) = BDC appointment-set rate × floor close rate.
If your blended close rate is below 8% on Google leads, the problem is usually in one of two places:
- BDC appointment-set rate is low (under 35%) — a follow-up speed and script problem
- Floor close rate is low (under 40%) — a process or inventory problem
Separate these metrics before diagnosing the fix.
How to Calculate Your True Cost Per Sale
CPL is a useful proxy metric. Cost Per Sale is the number that actually maps to gross margin.
Formula: Total ad spend ÷ attributed vehicles sold = Cost Per Sale
At $10,000/month ad spend and a 10% close rate on 100 leads = 10 sales = $1,000 cost per sale. If your average front-end gross is $2,000–$3,000 per unit, that's a 2–3x return on ad spend — healthy.
If your close rate is 4% on those same 100 leads: 4 sales = $2,500 CPS. Now you're at breakeven or worse on front-end gross. The CPL didn't change. The close rate destroyed the economics.
Use VELO's CPL Calculator to model how changes in close rate affect your cost per sale at different budget levels. Small improvements in close rate have a larger impact on unit economics than equivalent improvements in CPL.
When to Worry About Close Rate vs. CPL
Fix close rate first if:
- Your CPL is at or below benchmark but you're not hitting unit targets
- Your BDC appointment-set rate is below 40%
- Your floor close rate has dropped below 50%
- You're getting lots of leads from Facebook but very few sales
Fix CPL first if:
- Your close rate is healthy (10%+ on Google, 6%+ on Facebook) but cost per sale is too high
- You're hitting unit targets but losing money on ad spend
- Your CPL has increased 30%+ month-over-month without explanation
Most of the time, both need attention. But close rate problems compound — if you fix CPL without fixing close rate, you just drive more unconverted leads at lower cost.

The Number That Sits Above Both
Your close rate and CPL are inputs to one number: cost per sold unit from digital advertising. Know that number. Compare it to your gross margin. If the math works, scale. If it doesn't, figure out which lever (CPL or close rate) moves the needle faster in your store.
Most BC dealerships don't know their cost per sold unit. That's the gap.
We'll calculate your actual CPL, close rate by channel, and cost per sale from your current ad setup — and show you exactly where the number can be improved.
