See what your marketing could be doing differently.
Three sliders, one estimate. We compare your numbers against the top-quartile ROAS in your industry — the same benchmark we run our own audits against.
Estimates based on industry-standard performance benchmarks for SMB ad accounts. Actual results vary based on offer quality, market saturation, seasonality, and operational capacity. The audit identifies which factors apply to your business.
Actions you can implement immediately for Automotive services:
- Audit your call trackingMost automotive accounts miss 40–60% of conversions from phone bookings. Set up CallRail with dynamic number insertion and pipe the data back into Google Ads as conversion events.
- Restructure by branch + serviceOne PMax campaign across three branches is the most common leak we see. Split by physical location and by service intent so bid strategies match buyer behaviour, not Google's defaults.
- Fix conversion attribution windowsDefault 30-day post-click windows hide same-week walk-ins for car-services buyers. Tighten to 7-day click + 1-day view and you'll see real-time signal change overnight.
- Add booked-appointment as the only conversion goalIf form fills, page views, or clicks count as conversions, your ROAS is fiction. Strip the conversion list down to booked-appointment + completed-service.

What this measures — and who it's for
Most SMBs know their ad spend and a ROAS number — few know how far that sits from a realistic top-quartile for their industry. This marketing ROI calculator estimates the revenue gap between your current return and a benchmark range drawn from SMB portfolio patterns. Three inputs, one clear opportunity figure. Built for owners who want a fast reality check before a deeper audit. It does not replace account access; if tracking is broken, the gap will be fiction — run Tracking Trust Score first when dashboards feel "too good."
Best for
- Owners who know spend and a ROAS number but not how far they sit from peers
- Teams pitching budget increases with a simple opportunity figure
- Prospects deciding whether a deeper audit is worth it
Not a fit when
- Finance models that need break-even unit economics (use Break-Even ROAS)
- Dashboards you already know are tracking-fiction
What the score covers
Current return
Spend and reported ROAS or revenue.
Benchmark band
Median and top-quartile ROAS for your industry.
Opportunity
Estimated monthly revenue if you closed the gap.
Directional SMB ranges we calibrate against
- Benchmark ROAS bands blend Zenos SMB portfolio outcomes with public paid-media ranges (WordStream / LocaliQ-style) — blended media, not search-only.
- If tracking is broken, the gap is fiction; run Tracking Trust Score when dashboards feel “too good.”

How we score this — and what we don't claim
Benchmarks follow a fixed source hierarchy: (1) anonymised Zenos SMB client portfolio ranges (US/UK-weighted), (2) public industry reports (WordStream, LocaliQ, and similar summaries), (3) platform-published case ranges used only as sanity bounds. Scores are directional self-diagnosis anchors — not guarantees and not a live account inspection.
