JENKINS AUTO GROUP OCTOBER 2026 · RANDOM ON/OFF TEST

With SpeedLayer ON,
3.6 X the sales-lead action rate.

Traffic was randomly assigned to SpeedLayer on or off. Across 23 stores, the ON group recorded 3.05 lead actions per 100 measured users. The OFF group recorded 0.84. Each action is a sales-lead step: a call, text, chat, or form.

You pay to bring shoppers to the site. When a shopper leaves before contact, your team cannot follow up.

The ON group still had 3.2 X the action rate after we matched the store mix. Auto Genius reports random assignment; the workbook does not include assignment logs. These events are not unique CRM leads or sold cars.

01 / THE RESULT

More lead actions
per user.

A random ON/OFF traffic split shows what SpeedLayer changed: the rate of calls, texts, chats, and forms. Check the rate for each store below.

01 / GOOGLE PAGESPEED REPORTS↗

How quickly
does it load?

Separate Google PageSpeed mobile reports with SpeedLayer off and on. These are scores, not shopper outcomes.

02 / SALES-LEAD ACTIONS↗

More actions.
More chances to connect.

These sales-lead actions are calls, texts, chats, and forms. One shopper can take more than one action. Auto Genius says the ON/OFF assignment was random.

How we measured
ONE REAL WEBSITE

Same website. Two Google PageSpeed reports.

Step 1: open the “without” Google report. Step 2: open the “with” report. Compare the mobile scores for the same website; each link opens Google in a new tab.

02 / YOUR STORES

Every store.
Its own story.

Find your store for a plain-language comparison and a clear next check. The five stores missing usable measurements are listed separately below.

03 / TWO REPORTS · ONE STORE AT A TIME

What does
speed protect?

Choose a store. Enter your monthly numbers. See the cost of each car sold with SpeedLayer on and a possible off case. The off case is a model, not a measured result.

Select a measured store to explore its observed engagement and lead-action rates.

Build your report

Did more sessions end with engagement?

See the engagement and bounce rates for your store. Use your ad spend to see a possible dollar difference. These are not measured paid-ad dollars saved.

Choose a measured store.
Possible spend linked to engaged sessionsChoose a store and enter ad spend

We do not have separate data for paid traffic.

The engagement data are for all traffic on selected Mondays. Your ad spend is a monthly amount. The model assumes that paid traffic acts the same way. We have not tested this assumption. A bounce does not prove that you wasted ad spend.

04 / CLOSE THE GAPS

Not a bad result.
A missing signal.

These five properties do not have a usable shopper-action comparison. We do not rank them as poor performers. Here is the measurement step for each.

05 / SHOW THE WORK

Trust the numbers.
Know their limits.

A decision to stay deserves evidence you can inspect, not a magic percentage. The source workbook is retained privately; individual Google PageSpeed mobile reports are linked from the store views.

Who is included?

What does the speed comparison show?

What counts as a lead action?

Lead actions are forms, texts, chats, and mobile click-to-calls. The rate divides total action events by deduplicated GA4 users, not visits; the group sums those store-level user counts, so a person visiting two stores can appear twice. This is a lead-action signal, not deduplicated leads, sales, revenue, or actual ROI. Auto Genius says eligible traffic was randomly assigned to ON or OFF. The workbook has audience totals, not assignment logs.

What about installation health?

THE NEXT DECISION

Keep the site fast.
Keep shoppers
on the path to contact.

Before you remove SpeedLayer, check the ON/OFF result for each store. Fix missing measurements. Keep the shoppers who are ready to contact you.
