How to set up tROAS when you're not an ads expert
If you've ever opened your Google Ads bidding settings and felt your eyes glaze over at the term tROAS, you're in good company. It sounds like something only a paid-media specialist should touch. In truth, it's one of the most powerful levers an SMB has for spending ad budget wisely — and you can set it up without a single line of code or a £5,000-a-month agency.
This guide explains what tROAS does, the one catch that trips up almost every lead-gen business, and how to pick a starting target so you don't strangle your campaigns on day one.
What tROAS is, in plain words
tROAS stands for "target return on ad spend." It's an automated bidding strategy: instead of telling Google how much to bid per click, you tell it the return you want, and Google's algorithm bids automatically on each auction to try to hit that number across your campaign.
Return on ad spend is just revenue divided by spend. A tROAS of 400% means "for every £1 I spend, bring me back £4 in value." Set that target, and Google leans into the searches, audiences, and times of day most likely to clear it — and pulls back where the math doesn't work. You hand the algorithm a goal instead of a thousand manual bid decisions.
The catch nobody warns lead-gen businesses about
Here's where most SMBs go wrong. tROAS only works if Google knows the real value of each conversion — not just that a conversion happened.
For e-commerce this is automatic: someone buys a £90 product, the platform records £90. But if you run on leads — demo requests, quote forms, bookings — your "conversions" are usually all counted the same, each worth, say, £1. When every lead is worth the same, a 400% target is meaningless: the algorithm can't tell your best lead from your worst, so it has nothing to optimise toward.
This is exactly why so many lead-gen accounts flip on tROAS, see no improvement (or a drop), and conclude "it doesn't work for us." It does work — but only once you feed it real conversion values that reflect which leads actually turn into revenue. A high-value lead and a tyre-kicker must not look identical to the algorithm.
What you need in place first
Before you touch the tROAS setting, two things have to be true:
- Real value tracking. Your ad account needs to receive a meaningful euro value for each lead — ideally based on what that lead is actually worth to your business (deal size, win probability, or closed revenue from your CRM). Without this, see the catch above.
- Enough conversion volume. The algorithm learns from data. As a rough guide, you want at least 15–30 conversions per campaign over the past 30 days before tROAS has enough signal to behave predictably. Below that, results swing wildly.
Getting real values from your CRM into Google, Meta, or LinkedIn is the fiddly part where most teams stall. It's the whole reason value-based bidding exists as a discipline — and what PipeValue automates: it reads the true € value of each lead from your CRM and sends it to the ad platforms so tROAS finally has something real to chase.
How to pick a starting target (don't strangle it)
The single most common rookie mistake is picking an ambitious target out of optimism rather than data. Setting tROAS to 800% because that sounds healthy will choke your campaign — the algorithm decides almost no auction clears the bar, your bids collapse, and your lead volume falls off a cliff.
Instead, anchor to reality:
- Find your current return. Look at the ROAS your campaign is already producing over the last 30–60 days. That's your baseline.
- Set your first target at or just below that number. If you're currently at 350%, start at 300–350%. The goal is to switch strategies without shocking the system.
- Improve in small steps. Once the campaign is stable (give it 2–4 weeks), raise the target by 10–15% at a time and watch what happens to volume.
The setup, step by step (high level)
You don't need to be technical to do this. At a high level:
- 1. Get value data flowing. Make sure your conversions carry real euro values, not flat counts. (This is the prerequisite that makes everything else worthwhile.)
- 2. Let conversions accumulate. Run for a few weeks so you have enough volume and clean value signal before switching.
- 3. Open your campaign's bidding settings. In Google Ads, go to the campaign, then Settings → Bidding, and choose "Target ROAS" (or "Conversion value" with a target ROAS).
- 4. Enter your baseline target. Use the at-or-just-below number from the section above — not a wishful one.
- 5. Leave it alone to learn. Expect a learning period. Don't panic at week-one wobble.
- 6. Review and nudge. After a few weeks, check return versus volume and adjust the target in small steps.
Common mistakes to avoid
- Target too aggressive. The number-one killer. An over-ambitious target starves the campaign and tanks volume. Start near your real baseline.
- No value data. Running tROAS on flat, identical conversion values gives the algorithm nothing to optimise. Real values first, always.
- Too little volume. Below roughly 15–30 conversions a month, tROAS can't learn. Use a simpler strategy or consolidate campaigns until you have signal.
- Impatience. Changing the target every few days resets learning and creates chaos. Give each change 2–4 weeks before judging it.
Get those four right and tROAS stops being scary jargon and becomes what it's meant to be: a tireless optimiser pointing your budget at revenue instead of raw form-fills. For a one-screen refresher on the term itself, the tROAS glossary entry has you covered.
FAQ
Is tROAS better than maximise conversions for lead-gen?
Only if you feed it real conversion values. Maximise conversions chases the most form-fills; tROAS chases the most revenue per euro spent. If every lead is counted as worth the same, tROAS has nothing extra to optimise toward and you may as well use a simpler strategy. With true values flowing in, tROAS is the stronger choice because it pushes spend toward the leads that actually become customers.
How many conversions do I need before tROAS works?
As a rough rule of thumb, aim for at least 15 to 30 conversions per campaign over the trailing 30 days before switching to tROAS, and more is better. With fewer than that the algorithm cannot learn reliably and your results will swing wildly. If you're low on volume, start with a simpler value-based strategy or consolidate campaigns to pool conversions.
What is a good starting tROAS target?
Start from the actual return your account is already producing, then set your first target at or slightly below that number rather than above it. A common mistake is picking an ambitious target out of thin air, which starves the campaign and crashes your volume. Let the campaign stabilise for a few weeks, then nudge the target up in small steps.
Do I need a developer to set up tROAS?
You don't need a developer to switch a campaign to tROAS — that's a setting in the bidding section. The harder part is getting real conversion values out of your CRM and into the ad platform, which is where most teams get stuck. A tool like PipeValue handles that connection so the value data flows in automatically, no engineering required.
