How to Fire Your Ad Agency (2026 Step-by-Step)
August 17, 2026

Subscription supplement brands should run Google Ads on what a subscriber is worth, because first-order ROAS misses everything a customer pays after the first order. In 2026 Google lets you hand it that number through the new customer value setting. The rest is setup: keep rebills out of your purchase conversion and your claims inside Google's supplement policy.
If you sell a supplement on subscription, first-order ROAS is the wrong number to run Google Ads on. It is not a little wrong either, because it pushes your bidding away from the exact customers your business depends on.
Here's why: Google only sees the order that happens at checkout. A subscriber who'll pay you every month and a one-time buyer who never comes back look about the same on day one and sometimes the subscriber looks worse. So Smart Bidding does what you told it to do and chases the cheaper first order.
The good news is that Google built a way to fix this and most of it is setup rather than strategy. The rest of this post walks through the four places the money leaks, why the default setup causes them and what the fixed version looks like in 2026.
There are four places I'd look first and they usually show up together.
1. Bidding to the first order. Your campaign has a target ROAS and the only value Google has is the checkout total. If your subscription comes with a first-order discount, the subscribe-and-save discount makes your best customer look like your cheapest conversion. Smart Bidding sees a smaller order and leans toward the one-time buyer, which is the opposite of what you want.
2. Rebills sent back to Google as purchases. Renewals happen in your billing system, not on your site. Some setups import every order into Google Ads anyway, renewals included. When that happens Performance Max gets credit for revenue it didn't drive and the ROAS looks great. Budget then drifts toward people who already buy from you and nobody complains, because the number keeps going up.
3. Paying to win back people who never left. Subscribers rarely come back to your checkout because the product just shows up every month. Google's own help page on detecting customer segments says its autodetection builds from up to the last 540 days of activity and recorded purchases and that it's less complete because people clear cookies and opt out. So an active subscriber who never comes back to your checkout looks brand new to Google. When they search your brand name to skip a shipment, you can end up bidding new-customer prices for that click.
4. Claims that get products disapproved. Google's Healthcare and medicines policy doesn't allow supplements with active pharmaceutical or dangerous ingredients. It also blocks products that imply they work like prescription drugs, plus anything marketed as safe or effective for preventing, curing or treating a disease. There's a separate list of unapproved pharmaceuticals and supplements too. Merchant Center applies the same rules to Shopping in its own Healthcare and medicines policy, which means your product feed is ad copy as well. A title like "Immune Gummies That Fight Colds" is asking for a disapproval that "Immune Support Gummies" probably wouldn't get.
Because Google only knows what your tag tells it and the default purchase tag tells it about one order.
That tag fires at checkout with the value of that order. Nothing after it reaches Google unless you send it. Your billing app knows a customer is on shipment six, but Google Ads has no idea, so the bidding treats month one as if nothing comes after it.
Even Google's fix starts from order math. When you turn on the new customer acquisition goal, Google suggests a value to add for each new customer. Its setup guide says that recommended value is based on your average order value across prior campaigns. AOV has no idea you have subscribers. The same page gives directional guidance of valuing a new customer at 2x a regular customer. That's a fair starting point for a brand where people buy twice and a bad guess for one where people stay a year.
There's also a reporting trap that catches people after they fix the bidding. Google's guide notes that the Conversion value column includes both the original order and the extra value you add. So once you set a new customer value, the ROAS column stops being revenue. It is now revenue plus your own estimate and anyone reporting it to you as revenue is grading their work with a number you wrote.
A traditional agency can run a solid Performance Max campaign, but the person on your account is usually managing 10+ other accounts and reports whatever number the platform hands them. If you've seen that go sideways before, these are the signs your ad agency isn't working.
It's five changes and none of them are exotic. They just have to be done in the right order.
1. A first-order-only purchase conversion. Your primary purchase action should fire on first orders only. Renewals either stay out of Google entirely or get counted as a secondary action that bidding ignores. Without this, everything else you do is built on inflated numbers.
2. A new customer value you calculated yourself. Google adds this value to a new customer's purchase conversion and it's what tells the bidding a subscriber matters more than a single order. Work it out from your own subscription data, not a benchmark. With made-up numbers to show the math, say a first subscription order is $40 and your data shows a new subscriber pays for four more $40 shipments inside the window you care about. Then the extra value is $160. If your target ROAS runs on margin instead of revenue, put margin in here too so both sides of the math use the same units.
3. A window you can actually afford. I'm not going to give you a payback window, because there is not one that is true for every subscription business. Some brands can float a long wait between paying for a customer and earning it back and some can't. Pick the window your cash can handle and say it out loud before you set the number. First-order ROAS sells your subscribers short, but an inflated lifetime value can overspend you just as fast.
4. An active-subscriber list in Google. Upload your current subscribers as a Customer Match list and refresh it on a schedule. Google's list requirements say a list needs at least 100 active members to be used in lifecycle goals. This is what stops Google from treating a loyal subscriber as a stranger.
5. The right mode for each campaign. Google's overview of customer lifecycle goals lists three acquisition modes. New Customer Value bids higher for new customers and is the one Google recommends when you have purchase goals. High Value New Customer goes further and works only in Performance Max and Search. New Customer Only is for strict acquisition budgets. For most subscription supplement brands I'd start with New Customer Value on Performance Max, Shopping and non-brand Search.
Then clean up the claims. Your ads and your feed should describe what the product supports rather than what it cures. The FTC's Health Products Compliance Guidance says health benefit claims need competent and reliable scientific evidence, so a claim you can't back up is a problem twice over.
For a real example, Plant People is a DTC supplement brand that worked with one of our Unicorn Marketers. Across their Meta and Google ads, subscription revenue went up 2.7x and total tracked revenue rose 87%, while their Google CPA dropped 46%. I'd look at the subscription number first, because that's the one first-order ROAS can't see.
You can do most of this in an afternoon and you do not need anyone's permission to look.
That last check is the one that changes minds. If the cohort revenue is much higher than the ROAS column suggested, you've been under-bidding on your best customers. If it's lower, you've been over-crediting Google for renewals. Either way you now know which.
If you're weighing whether to bring someone in for this, it helps to know what an ad agency actually costs before you compare options.
Someone who works in your Google Ads account and your subscription data in the same week and who gets why the two disagree.
That sounds simple but it is a rare combination. A lot of strong Google people never open a billing dashboard and a lot of retention people have never set up a lifecycle goal. The fix lives in the gap between them. It also is not a one-time job, because your retention moves and the value you give Google has to move with it.
This is the kind of person we look for. The 2026 UM Vetting Benchmark shows fewer than 1% of marketer applicants pass our 79-point vetting process across 5 stages. Each Unicorn Marketer runs 3 to 5 accounts at a time, which is what makes it possible to check cohort data every week instead of once a quarter. If you're wondering why that number matters so much, here's how many accounts one person can really manage.
Use lifetime value, because first-order ROAS misses everything a subscriber pays after the first order. Google only sees the checkout order unless you tell it more. The new customer value setting lets you add the extra value a subscriber brings to their first purchase. Calculate it from your own retention data and pick a payback window your cash can actually handle, rather than borrowing a number from someone else's business.
It can be, as long as it's set up for subscribers. Run it with a first-order-only purchase conversion, a new customer value based on your own retention data and an active-subscriber Customer Match list. Without those, Performance Max tends to chase cheap first orders and repeat customers. Keep your feed and assets inside Google's Healthcare and medicines policy so products don't get disapproved.
Google's suggested value is based on your average order value and its directional guidance is about 2x a regular customer. For a subscription brand, a better starting point is what a new subscriber pays you over a window you can afford, minus the first order. If your target ROAS runs on margin, use margin here too so the math matches.
Yes, most can. Merchant Center's Healthcare and medicines policy blocks unapproved supplements, products with active pharmaceutical or dangerous ingredients and anything marketed as preventing, curing or treating a disease. Your product titles and descriptions count as ad copy, so a disease word in a title can get an otherwise fine product disapproved. Check the country rules before you expand.
Two common reasons. Renewals might be getting imported as purchases, which credits Google for revenue it didn't drive. Or you've added a new customer value and Google's Conversion value column now includes that added value on top of the real order. Either way the ROAS column is not pure revenue anymore, so compare it with your actual subscription cohort data.
Upload your active subscribers as a Customer Match list, refresh it on a schedule and use it in the customer acquisition goal. Google's autodetection relies on purchases it has seen and subscribers rarely come back to your checkout, so it can miss them. A list needs at least 100 active members to be used in lifecycle goals.
