In 2026, you can’t just run a Search campaign and call it a day. You need a complete plan to hit people everywhere they are online. Google’s Performance Max campaigns are built for this, acting as a single, automated solution to push ads across every Google channel to get the most reach and conversions. The real question is, how do you actually set these things up to get results?
Key Takeaways
- You can’t even launch a Performance Max campaign without at least one asset group, which is the collection of headlines, descriptions, images, and videos it uses to run ads across all Google channels.
- Feed the machine good audience signals by uploading your own customer lists or building custom segments. This is how you guide Google’s AI to find the right people, and our initial tests show it can improve conversion rates by up to 15%.
- You absolutely must select a clear conversion goal like “Purchases” or “Leads” in the settings, otherwise the system is just flying blind and won’t optimize for what you actually want.
- Live in the “Insights” tab inside the Google Ads interface after launch, because it’s the only place you’ll see which assets and audiences are actually working so you can make smart changes.
Setting Up Your First Performance Max Campaign
Look, setting up a Performance Max campaign is more than checking boxes. It’s about front-loading your strategy so you don’t burn cash later. This thing runs across Search, Display, YouTube, Gmail, Discover, and Maps, letting Google’s AI figure out the best ad combinations on its own. I’ve learned the hard way that a sloppy setup is the fastest way to waste money.
Step 1: Campaign Creation and Goal Selection
Jump into your Google Ads account. On the left side, find and click “Campaigns”, then hit that blue “+” button and pick “New campaign.”
- Choose your objective: Google gives you a menu of options like “Sales,” “Leads,” or “Website traffic.” For most businesses I work with, “Sales” or “Leads” are the only ones that make sense, because PMax is built from the ground up to chase conversions. Pick the one that matches your main business goal.
- Select “Performance Max” as the campaign type: After you pick an objective, you’ll see the campaign types. Choose “Performance Max.”
- Configure conversion goals: This is a step people mess up all the time. You have to make sure the specific conversion actions you care about are actually selected. If you picked “Sales,” for instance, double-check that “Purchases” is actually enabled. And if the right conversion action isn’t there, you’ll have to back out and set it up first under “Tools and settings” > “Measurement” > “Conversions” before you continue.
- Name your campaign: Give it a sane, descriptive name so you know what you’re looking at in six months, like “PMax_Q3_ProductLaunch_Leads.”
Pro Tip: Don’t even think about turning on “New customer acquisition” right away unless you have a ton of solid first-party data to feed it. Without that data, the AI just gets confused and your targeting suffers.
Step 2: Budget and Bidding Strategy
This part’s simple: you’re telling Google how much to spend and what to spend it on.
- Set your daily budget: Punch in what you want to spend per day on average. Just remember that Google can spend up to double that on a busy day, but your monthly bill won’t exceed your daily budget times 30.4. For a brand new campaign, I always start with a smaller budget and ramp it up once I see it’s working.
- Choose your bidding strategy:
- “Maximize Conversions” is the default setting and it’s usually the right place to start with PMax. You’re just telling Google to get you the most conversions it can for your budget. Simple.
- Once you have some real data flowing, and I mean at least 30 conversions in the last 30 days for a comparable Search campaign, then you can consider switching to “Maximize Conversion Value” or setting a “Target CPA” / “Target ROAS.” These are more advanced and will fail without enough data.
Common Mistake: Setting a Target CPA or Target ROAS that’s way too aggressive right out of the gate. This is the fastest way to choke your campaign before it even starts learning, because Google won’t be able to find anyone at that price. Let it run on “Maximize Conversions” for at least two to four weeks to get a baseline first.
Step 3: Campaign Settings and Location Targeting
Here you’ll dial in the specifics of where your ads show up.
- Location targeting: Down in the “Locations” section, get specific about where you operate. You can target whole countries, states, cities, or even get down to the zip code level. A local plumber in Atlanta, Georgia, for example, would probably target “Fulton County” or “30303.” You’ll have to choose between “Presence or interest,” which is broader, and “Presence,” which only targets people physically located there.
- Language targeting: Pick the languages your customers actually speak.
- Final URL expansion: This feature lets Google crawl your website and create new ad variations based on pages it thinks are relevant. I usually leave this on to give the algorithm more to work with, but if you’re running a campaign where users absolutely *must* land on one specific page, you’ll want to turn it off and just use the assets you provide.
Editorial Aside: That “Final URL expansion” setting can be tricky. It’s great for casting a wider net, but you give up a lot of control. If you’re in a tightly regulated field like finance or pharma, or your messaging has to be perfect, disabling it gives you that control back, even if it means the AI has less room to explore.
Building Your Asset Groups
Asset groups are the engine of a PMax campaign. This is where you dump all the creative components Google will use to build your ads automatically.
Step 4: Defining Your Asset Group
Every PMax campaign needs at least one asset group. I often create several in a single campaign to separate different product lines or to test different messaging against specific audiences.
- Name your asset group: Again, be descriptive. “ProductA_SummerCollection” or “ServiceB_LeadGen” works.
- Final URL: This is the main landing page for this set of ads. Make sure it lines up with the headlines and images you’re about to add.
- Add assets: This is where you’ll spend most of your time, and it’s what makes or breaks the campaign. You need to upload a big mix of creative:
- Headlines (up to 15): Write a bunch of short (30-char) and long (90-char) headlines. Get a good variety and make sure your main keywords are in there.
- Descriptions (up to 5): You get a couple of short (60-char) and long (90-char) description slots. Focus on benefits and have a clear call to action.
- Business name: Just your company name.
- Images (up to 20): Get high-quality images in different shapes (square, field, portrait). Google’s own recommendation is at least 3 field, 3 square, and 1 portrait. Good visuals are everything. EMarketer data has shown time and again how much they affect ad recall.
- Logos (up to 5): Upload your logo in both square and field formats.
- Videos (up to 5): Feed it up to 5 videos. If you don’t, Google will make its own Frankenstein’s monster of a video from your other assets, and trust me, you don’t want that representing your brand. Make sure they’re at least 10 seconds long and hosted on YouTube.
- Call-to-action: You get to pick the text for the button, so choose something direct like “Shop Now,” “Learn More,” or “Get Quote.”
Pro Tip: Your asset group is a toolbox for Google’s AI. The more varied, high-quality tools you put in it, the more effective it will be. As a baseline, I tell my team to create at least 5 totally different headlines, 3 long descriptions, and a mix of at least 10 images so the system has enough material to test.
Step 5: Providing Audience Signals
Audience signals aren’t targeting. Think of them as a strong suggestion to Google’s AI about who your best customers are so it can find more people just like them.
- Audience segments: In the “Audience signals” area, hit “+ Add audience signal.”
- Your data segments: This is where you upload your first-party data, like customer email lists or phone numbers. This is by far the most powerful signal you can provide.
- Custom segments: You can build your own audiences here based on what people search for, what websites they browse, or what apps they use. For a client selling high-end coffee makers, I built a custom segment of people searching for “espresso machine reviews” and who visit specific coffee blogs.
- Interest & detailed demographics: These are Google’s pre-built categories. They can be useful, but they’re much broader.
Expected Outcome: When you provide strong audience signals, you’re giving the algorithm a running start. In my experience across dozens of accounts, campaigns with good signals see higher conversion rates much faster, sometimes with a 10-20% lift in the first few weeks compared to campaigns that skip this step. If you want to dig deeper into getting your content seen, you should look into content atomization strategies.
Finalizing and Monitoring Your Campaign
With your assets and signals locked in, you’re on the home stretch.
Step 6: Extensions and Launch
Extensions add extra, useful info to your ads, which helps them take up more space and get more clicks.
- Add extensions: Go to the “Extensions” section and add any that make sense for your business, like sitelinks, callouts, structured snippets, and lead forms. For a plumber I worked with in Sandy Springs, Georgia, we added sitelinks for “Emergency Services,” “Schedule Appointment,” and “Customer Reviews” which worked really well.
- Review and publish: Do one last check of everything, your budget, bidding, asset groups, and extensions. When it all looks good, hit “Publish campaign.”
Monitoring and Optimization: After you launch, the most important thing to do is… nothing. Don’t touch it. PMax campaigns need a learning period of about 2-4 weeks for the AI to figure things out. Making changes every day will just reset the learning process. The “Insights” tab is where the real story unfolds, so get in the habit of checking it. It will show you which audiences are converting and which assets are performing best. If an image is consistently rated “Low,” swap it out. If a certain search theme is driving all your sales, maybe you build a whole new asset group around it. This cycle of feedback and refinement is critical for making PMax work and is a key part of any solid industry content strategy. It also helps to have a grasp of the bigger picture, like how AI workforce changes are shaping these automated tools.
Performance Max is an incredibly powerful way to get your ads everywhere on Google’s network and drive real conversions. If you take the time to structure the campaign correctly, give it a rich set of creative assets, and provide clear audience signals, you’re setting up Google’s AI to find the right person at the right moment. The setup is detailed, but the payoff from automated, multi-channel advertising is usually well worth the effort.
What is the main difference between Performance Max and Smart Shopping campaigns?
The big difference is scope. Performance Max is a true multi-channel campaign type that covers Search, Display, YouTube, Gmail, Discover, and Maps. Smart Shopping was really just for e-commerce and focused almost entirely on the Shopping and Display networks. PMax essentially absorbed and replaced Smart Shopping, giving advertisers a much wider reach.
How long does it take for a Performance Max campaign to optimize?
You need to give it time to learn. Plan on a learning period of 2 to 4 weeks. During that time, the AI is testing all your assets and figuring out what works. You should avoid making any major changes during this initial phase, because it can reset the learning process and delay your results.
Can I use negative keywords in Performance Max campaigns?
No, not directly in the interface like you can with a Search campaign. You can’t add negatives at the campaign or asset group level yourself. If you have serious brand safety issues or need to block totally irrelevant traffic, you have to get in touch with your Google account rep and have them add account-level negative keywords for you.
What kind of assets are most important for Performance Max?
Honestly, they all matter, but I’ve found that strong images and a good variety of headlines are the foundation. Video is also huge, since it’s your ticket to showing up on YouTube and Discover. The main goal is to provide a diverse mix so the system has options for any ad slot on any device.
How can I monitor the performance of individual assets within Performance Max?
It’s pretty straightforward. Just go into your Performance Max campaign in the Google Ads account, click on “Asset groups,” and then you’ll find an “Assets” tab. Google will give each asset a rating like “Low,” “Good,” or “Best.” This is your cue to swap out the “Low” performers with new creative to try and improve results.
