ServiceTitan + Google Ads: the integration most contractors don't know they need.

Google Ads knows, to the penny, what you paid for every click and call. ServiceTitan knows which jobs got booked and what each was worth. Out of the box neither can see the other's half — so the platform deciding where your budget goes is blind to the only number that matters: booked jobs.

There are three real ways to fix that: ServiceTitan's native Marketing Pro Ads, a Zapier connection, or an attribution layer that rebuilds the intake funnel itself. Here's what each of the integration options actually gets you, when the cheap one is enough, and the setup mistakes that inflate your numbers whichever route you pick.

Why your Google Ads account and ServiceTitan need to talk

Google's Smart Bidding — the automation that decides which searches your ads show on and how much you pay — optimizes toward whatever conversion you feed it. Feed it form fills and it buys more form fills, including the ones that never book. It can't see that the $80 lead from Campaign A rarely becomes a job while the $150 lead from Campaign B usually does — so it moves your budget toward Campaign A.

ServiceTitan knows which leads became jobs and what they were worth. It just has no way to tell Google unless you build the connection. Every month the two systems don't talk, you're buying leads instead of jobs and grading your ad spend on faith.

What "integrated" actually means

Strip away the vendor language and a real integration is one loop with five hops; miss any hop and your reports are decorative.

1. A homeowner clicks your ad. Google attaches a GCLID — Google Click ID, a unique tag identifying that exact click — to their visit.
2. Your website captures the GCLID and holds it while the visitor browses, calls, or starts a booking.
3. The visitor becomes a lead — a call, a form fill, or a finished booking — and the GCLID travels with them.
4. The lead becomes a Job in ServiceTitan, with revenue attached once it books and closes.
5. The Job and its revenue go back to Google Ads as an offline conversion — a conversion reported after the fact from your CRM, matched to the original click by its GCLID. Now Google bids for jobs, not clicks.

That closed loop — ad click to booked job and back — is what lead attribution means in practice. Everything below is just three different ways of building it.

Option 1: ServiceTitan Marketing Pro Ads (the native route)

Marketing Pro is ServiceTitan's paid marketing add-on; its Ads module is the native version of the loop above. Once connected, ServiceTitan mirrors your Google Ads campaigns by name, uses dynamic number insertion (DNI — swapping the phone number shown on your site per visitor so each call traces to its source) to capture the GCLID on calls, and sends lead-classified calls back to Google as conversions. Per ServiceTitan's setup docs, it creates the phone-call conversion action in Google Ads automatically the first time one fires.

For plenty of shops this is all they need. Its limits are structural, not quality problems: it's an added subscription on top of ServiceTitan, it only works inside ServiceTitan, and it measures the funnel you already have. If your booking experience converts poorly or after-hours calls die in voicemail, Marketing Pro will report that failure accurately — it won't fix it.

Option 2: The Zapier route

Zapier publishes a ServiceTitan-to-Google-Ads template that fires an offline conversion when a new job appears in ServiceTitan. For a low-volume shop, or an owner proving the concept before paying for anything, duct tape is a legitimate engineering material. Know where it breaks:

• It can't tell an appointment from a booked, sold job unless you build careful filters — so cancellations and no-shows get reported to Google as wins.
• It sends a conversion event, not revenue, unless you map job values by hand — so Google still can't tell a $99 tune-up from a $12,000 install.
• No dedupe logic: a job that gets edited or re-triggered can fire the conversion twice.
• It does nothing for phone calls — and call-tracking analyses of home services consistently find that most high-intent contacts arrive by phone. Your biggest channel stays invisible.

Option 3: Fix the funnel and the measurement together (where Peach fits)

Full disclosure: this option is us, so read it accordingly. Marketing Pro and Zapier measure the intake funnel you already have. Peach replaces the funnel — and the measurement comes wired through it.

Concretely: a booking flow showing live ServiceTitan slots and creating real Job records, an AI that answers and books the calls your CSRs can't get to, and SMS follow-up that recaptures abandoned bookings and missed calls. Every booking lands in ServiceTitan with its GCLID already attached, and booked-job revenue goes back to Google Ads as an offline conversion in under a minute. The step-by-step ServiceTitan connection guide covers the whole setup; most operators are live in 5–10 business days, and the ones coming from a contact-form website typically see online conversion climb from 10–20% to 50–65%.

Two honest caveats. If Marketing Pro is already measuring a funnel that converts well, you don't need us — see the rubric below. And if you run brands on Jobber or Housecall Pro alongside ServiceTitan, the same wiring works across all three — the one case where an independent layer beats any single CRM's native tool.

Which setup is right for you?

• All-in on ServiceTitan, happy with how your website converts, already paying for Marketing Pro: Marketing Pro alone is enough. You don't need a third-party layer, including ours.
• Low lead volume, or testing whether offline conversions are worth it before spending money: the Zapier route, with a calendar reminder to graduate off it.
• Form fills that never book, after-hours calls dying in voicemail, or multiple brands on different CRMs: that's the case for rebuilding the intake funnel with attribution built in — our lane.

The five setup mistakes that inflate your conversion numbers

These apply no matter which option you pick. Agency guides on ServiceTitan ad tracking keep flagging the same failures, and every one makes your numbers look better than reality — which is exactly why they survive.

1. Wrong count method. Google lets a conversion action count "every" conversion or "one" per click. Leave a phone-call action on "every" and one homeowner calling three times about the same job counts as three leads.
2. Duplicate conversion actions. The old website form tracking stays live while new offline conversions arrive, and one booking gets counted twice. If Google Ads reports more conversions than ServiceTitan has jobs, start here.
3. Default attribution windows. Homeowners click, research, and book weeks later — and Google credits the conversion to the click date, not the booking date, a quirk ServiceTitan's own docs call out. Short windows silently drop late bookers and make month-end reports look misaligned even when tracking is right.
4. CSR overrides. If CSRs type whatever the caller says to "how did you hear about us?", that manual answer can overwrite the tracked source. Callers say "Google" for everything — brand search, Maps, LSA, and paid ads collapse into one bucket.
5. Bidding on form fills. Everything is connected, but the form fill is still your primary conversion — so Google keeps optimizing for the top of the funnel while your booked-job data rides along as a spectator. Set booked jobs, or jobs plus revenue, as primary.

How to validate it's actually working

Don't trust the green checkmarks on the integration screen. Run one real lead through the whole loop and watch it come out the other side.

1. Click your own ad (or open your site with a test GCLID in the URL) and complete a test booking.
2. Confirm a Job exists in ServiceTitan with the correct campaign or source attached — not "direct" and not blank.
3. Open Google Ads → Goals → Conversions within a day or two and confirm the offline conversion arrived, with a dollar value if you're importing revenue.
4. Check that the booked-job conversion action is marked primary and the old form-fill action is secondary or removed.
5. If you're using DNI, repeat the test by phone: call the tracking number and confirm the call lands in ServiceTitan attributed to the right campaign.

FAQ

Does ServiceTitan integrate with Google Ads natively?

Yes — through the Marketing Pro add-on's Ads module. With DNI configured, ServiceTitan captures the GCLID on tracked calls and sends lead-classified calls back to Google as conversions, creating the phone-call conversion action automatically the first time one fires.

Do I need Marketing Pro to connect ServiceTitan to Google Ads?

No — Marketing Pro is required for the native route, but not the only route. Zapier can push basic job events for low-volume shops, and independent attribution layers close the same loop while also handling the booking flow and call tracking. What you can't do is meaningful conversion tracking with no connection at all.

What is offline conversion tracking?

It's reporting a conversion to Google after the fact from your CRM, instead of from your website at the moment of the click. The conversion is matched to the original ad click by its GCLID, so a job booked days later still credits the right campaign — and can carry the job's actual revenue with it.

Can my agency keep managing the account?

Yes, under every option here. The integration changes what data flows into Google Ads, not who manages bids and budgets. Most agencies welcome it — booked-job conversions make their work easier to prove — and shared read-only reporting keeps everyone arguing from the same numbers.
