Google's PMax Guide Sets Up Tracking Last. A Small Business Should Start PMax at 30 Conversions a Month.

Google's new-user guide builds Performance Max before conversion tracking. Here's when PMax ads make sense for a small business and which defaults to change.

Chapter 2 showed where Google points a brand-new advertiser: straight into Performance Max. It also promised an explanation of why a small business should wait. This is that chapter.

Performance Max can work well. It just needs something a new small account doesn't have yet. Below: what Performance Max is, why it comes late rather than first, how to test it once the account is ready, and which of its default settings to change before it spends.

Chapter 10 of 16

Google's Setup Guide Builds the Whole Campaign Before It Walks You Through Conversion Tracking.

Google calls Performance Max a "goal-based campaign type." One campaign reaches every Google channel: YouTube, Display, Search, Discover, Gmail and Maps. You supply a budget, a goal and a set of headlines, images and videos, and Google's automated bidding decides where the ads run, who sees them and what to pay.

Read the steps in Google's setup guide for new users in order. You pick a goal. You write your ads: headlines, images and other assets. You pick a bid strategy. You set a budget and enter payment details. The tracking setup comes last, under next steps: "With your Performance Max campaign set up, you're now able to utilize conversion tracking."

For a small business, that's the wrong way around. A campaign that bids for conversions gets built before anything is counting them. Chapter 1 put tracking first for exactly this reason: automated bidding only works once the account can tell Google which clicks became customers.

David Smania, BrandRocket's founder, describes the result in one of his guide videos. Start with Performance Max before the account knows what success looks like, and "the Google algorithm is clueless," he says, because it has nothing to learn from. He calls starting there "very wasteful" and says he sees it over and over in the chiropractic accounts he audits.

A campaign that learns from conversions can't start before the conversions do.

Performance Max Has No Keywords and No Manual Bids. It Learns From the Conversions You Count, and a New Account Has None.

Everything this guide has built depends on two levers you hold yourself. Chapters 5 and 6 picked the searches. Chapter 7 set what each click is worth. Performance Max takes both levers away.

There are no keywords, only optional "search themes," which Google uses as hints rather than instructions. And there are no manual bids. The setup guide offers two strategies, Maximize conversions or Maximize conversion value, and points anyone with "a tight budget" to Maximize conversions. Chapter 7 covered what that one does: it tries to spend the whole daily budget every day.

Put that on a young account with five or ten conversions to its name, and Google is betting your full budget on very little evidence. It does so on six channels at once, on searches you never chose, at prices you never capped.

So Performance Max waits behind a gate. Our rule for it is the same 30 quality conversions a month that opens the broad-match Exploration campaign in Chapter 7, but held steady for longer, with both Search campaigns already running and feeding it real results. Six or seven months in is the usual pace; larger, busier accounts reach it sooner, and plenty of small accounts never reach it at all. That's not a failure. A small account that stays on square-bracket keywords and its own bids isn't missing anything it can afford.

A brand-new account has a second problem: even its few conversions may not be the right ones. A campaign trained on page views gets very good at finding people who look at pages. Chapter 1's cleanup has to come first.

Online stores are a partial exception, because product ads run through Shopping. The Ecommerce guide's chapter on Standard Shopping covers how a small store starts Shopping ads on manual bids and moves to Performance Max later.

Performance Max Puts Your Ads Back on the Display Network and Search Partners, the Two Networks You Just Turned Off.

Chapter 9 switched off two networks before launch: search partners and the Display Network. Performance Max brings both back. Google's help page describes the controls: its own surfaces are grouped together as "Google channels," while search partners and the Display Network each get a separate priority tier and can get their own optional daily budget. You can steer them, but both are part of the campaign's reach.

That matters most on a small budget. A few hundred dollars a month split across all of Google's channels plus search partners buys very little of any one, and in our experience the cheap placements tend to win the spend.

There's a second effect we see in the accounts we manage. In our experience, Performance Max treats past website visitors as a strong signal and spends on reaching them again on Display, YouTube and Discover, whether or not those visitors were ever likely to buy. If much of your site traffic is casual browsing, part of the budget follows the browsers.

One rule protects the work from earlier chapters. Google serves your Search campaign ahead of Performance Max when the search matches one of your square-bracket keywords. The square-bracket campaign from Chapter 6 keeps the searches it has already proven, even after Performance Max goes live.

Performance Max Can Take Credit for Customers Your Search Ads Were Already Winning.

When the account clears the gate, treat Performance Max as a test, not a replacement. Three conditions keep the test honest, and all three are easy to skip when a Google rep is on the phone.

Give it new money. Fund it with extra budget rather than moving money out of the Search campaigns that already work. If Search loses budget at the same moment Performance Max starts, you can't tell whether Performance Max found new customers or simply took credit for ones Search would have brought in anyway.

Decide the exit before you start. Write down what a real lead is allowed to cost, based on what leads cost in Search today, and how long the test runs. If it misses that number by the end date, pause it. Without a line drawn in advance, it's tempting to keep adjusting a campaign that isn't working.

Change one thing at a time. A new campaign type, a new budget and a new bid target in the same week leave you guessing which one moved the numbers.

Then judge it on cost per real lead and on whether those leads became customers, not on clicks or impressions. Ask whoever answers the phone whether the Performance Max leads sound like the Search leads: the same services, the same area, the same kind of job. A lead that costs half as much but never books isn't cheaper. Performance Max reaches a lot of people cheaply. That isn't the same as reaching people who hire you.

A test with no finish line never fails. That's the problem with it.

Performance Max Can Send Clicks to Any Page on Your Site and Make Its Own Video. Both Are On by Default.

Before the campaign spends its first dollar, a handful of its defaults need changing.

Swapping your landing page. A setting called Final URL expansion starts out on. With it on, the page you built for the ad is only a suggestion, and Google's own page admits the swaps don't always land where you'd want. For a small business, the stray landing page might be a careers page, a blog post or a promotion that ended last spring. Switch it off so every click lands on the page you built for it (Chapter 4), or exclude the pages that should never get paid traffic.

Video. Upload no video, and Google's AI assembles one from your images and text; that setting is on by default. Upload a short clip of your own instead. A phone video of the owner at work, the same person Chapter 8 put in the headlines, beats a slideshow built from your logo.

Brand exclusions. Add your business name as a brand exclusion. Google suggests this when brand searches already run in their own campaign, which yours do (Chapter 2). Without it, people who typed your name can end up counted as Performance Max wins.

The goal. Count only the real lead or sale, as Chapter 1 set up. A Performance Max campaign told to count page views or button clicks will find plenty of both and very few customers.

A few more settings round it out:

Most Performance Max defaults widen the campaign. On a small budget, your job is to narrow it back down.

Next: YouTube Can Wait While Search Ads Still Have Room to Grow.

Performance Max is where many small accounts get pushed first and where many of them lose money early. Up next, Chapter 11 takes on Demand Gen and YouTube ads, and why a small budget belongs in Search until Search has nothing left to give.

Every chapter so far, from tracking and budget to keywords, bidding, ad copy and launch settings, is on the guide's home page.

When we take over an account through Google Ads management, a Performance Max campaign that launched before conversion tracking is one of the first things we pause. Doing it yourself? Open your campaigns list tonight. If Performance Max is there and the account counts fewer than 30 real leads a month, pause it and put that money into your square-bracket Search campaign.
