ServiceTitan and Google Ads: How to Close the Loop on Lead Attribution

Here’s a question most contractor marketing agencies can’t answer: which Google Ads keyword generated $47,000 in booked revenue last month?

Not leads. Not clicks. Not impressions. Actual revenue that hit your bank account.

If your agency is reporting on leads and calling it a day, you’re making budget decisions with half the picture. Leads are nice. Revenue is what pays for trucks and technicians and everything else that keeps your business running.

This is what proper ServiceTitan and Google Ads integration gives you. When these two systems talk to each other properly, you can trace the entire path from someone clicking your ad to calling your office to booking a job to the final invoice amount. That’s not a marketing fantasy. It’s a Tuesday for us.

Why Attribution Matters More Than Lead Volume

Let’s say you have two campaigns running. Campaign A generates 50 leads at $40 each. Campaign B generates 20 leads at $80 each. Most reports would tell you Campaign A is the winner. Twice the leads at half the cost, easy call.

But here’s what happens when you close the loop with ServiceTitan: Campaign A’s leads convert to booked jobs at 30% with an average ticket of $350. Campaign B’s leads convert at 60% with an average ticket of $3,200.

Campaign A generated $5,250 in revenue on $2,000 in ad spend. Campaign B generated $38,400 in revenue on $1,600 in ad spend. Campaign B isn’t just better. It’s operating in a completely different universe of ROI.

You would never know this looking at lead volume alone. And yet, that’s exactly how most agencies optimize: more leads, lower cost per lead, pretty dashboard. Meanwhile, the campaigns actually driving your business might be getting their budgets cut because they “only” generated 20 leads.

How the Integration Works

Connecting ServiceTitan to your Google Ads campaigns isn’t a single button press. It’s a stack of tools working together. Here’s the chain:

The Attribution Stack

• Google Ads tracks the click. A person clicks your ad, and Google records the campaign, ad group, keyword, and search term.
• Call tracking (CallRail) assigns a unique phone number to each session. When the person calls, CallRail captures the caller info and ties it to the exact keyword and ad that drove the visit.
• CallRail passes the lead data to ServiceTitan. The call recording, caller info, and marketing source all flow into ServiceTitan as a new lead.
• ServiceTitan tracks the job lifecycle. From booked call to dispatched technician to completed job to final invoice, everything is logged.
• Revenue data flows back to your reporting. You can now see which Google Ads campaigns and keywords are generating actual revenue, not just phone calls.

The result is a closed loop. Ad click → phone call → booked job → revenue. Every step is tracked, every dollar is attributed.

Setting Up the Integration: The Practical Steps

Google Ads Conversion Tracking

Start with proper conversion tracking in Google Ads. You need to track both form submissions and phone calls as conversions. Use Google’s call reporting for click-to-call conversions, and make sure your conversion window is long enough to capture the typical booking timeline (we usually set 30–60 days for home services).

CallRail Configuration

CallRail is the bridge between Google Ads and ServiceTitan. Set up:

• Keyword-level call tracking with dynamic number insertion on your website
• Google Ads integration in CallRail so call conversions flow back into your Ads account
• Call recording enabled (with proper disclosure) so you can assess lead quality, not just quantity
• The CallRail-ServiceTitan integration so leads automatically create customer records in ServiceTitan

ServiceTitan Marketing Configuration

Inside ServiceTitan, configure your marketing sources to align with your Google Ads campaign structure. This is critical, if your marketing source tags in ServiceTitan don’t map cleanly to your campaign structure, your attribution data becomes a mess.

Best practice: create marketing sources in ServiceTitan that mirror your campaign names. If you have a campaign called “AC Repair – [Your City],” create a matching marketing source. When CallRail passes the lead to ServiceTitan, it tags it with the correct source.

Reporting and Optimization

Once the integration is running, your reporting changes completely. Instead of looking at cost per lead, you’re looking at cost per booked job and return on ad spend by campaign, by service line, even by keyword.

This data tells you exactly where to put your next dollar. Double down on the campaigns generating high-revenue jobs. Fix or cut the ones generating cheap leads that never convert. It’s a fundamentally different way to manage your ad spend.

Common Pitfalls (and How to Avoid Them)

Mismatched Marketing Sources

If your ServiceTitan marketing sources don’t align with your campaign structure, attribution gets muddled. Take the time to map these correctly from the start. It’s tedious setup work that pays dividends for as long as you’re running ads.

Not Using Dynamic Number Insertion

Static tracking numbers on your website can’t tell you which keyword drove the call. Dynamic number insertion (through CallRail) swaps the phone number displayed based on the visitor’s session, giving you keyword-level attribution. Without it, you know a call came from Google Ads but not which campaign or keyword, and that’s not enough.

Ignoring the Conversion Lag

In home services, someone might click your ad on Monday, call on Wednesday, and get the job done the following week. If you’re evaluating campaign performance on a one-day or even one-week window, you’re missing conversions that haven’t happened yet. Give your data 2–4 weeks to mature before making big budget decisions.

Not Listening to Calls

Call tracking gives you recordings. Listen to them. Not every lead is a good lead, and not every “conversion” is actually a booked job. Listening to calls helps you spot issues with your CSRs, identify common customer questions, and understand the real quality of leads each campaign produces.

What This Looks Like in Practice

When this integration is working, your monthly reporting looks fundamentally different. Instead of a slide that says “You got 87 leads this month at $54 average cost per lead,” you get something like:

• Google Ads generated $142,000 in booked revenue this month.
• The AC Repair campaign produced 34 booked jobs with an average ticket of $1,800 and a 6.2x return on ad spend.
• The HVAC Installation campaign produced 8 booked jobs with an average ticket of $8,400 and a 9.1x return on ad spend.
• The keyword “ac repair near me” generated $47,000 in attributable revenue.

That’s not a prettier report. That’s a different conversation entirely. It’s a conversation about revenue, not vanity metrics. And it’s the conversation your CFO and your operations manager actually want to have.

Stop Guessing. Start Attributing.

We live in ServiceTitan and Google Ads every day. Connecting these systems so you can see real revenue attribution (not just lead counts) is one of the most impactful things we do for our clients. It’s not glamorous work, but it’s the work that changes how you make decisions.

If you’re sitting on a ServiceTitan account and Google Ads campaigns that aren’t talking to each other, let’s fix that.
