Trying to decide between Performance Max, Search, or Demand Gen?

Each serves a different role in your advertising strategy, and the right fit depends on what you’re aiming to achieve and who you are trying to reach.

PMax vs. Search

If your goal is to reach more potential customers across multiple Google platforms using automation, Performance Max is your best bet. It uses machine learning to optimize ads across Search, Display, YouTube, Gmail, and Discover with minimal manual input.

In contrast, Search campaigns give you more control and are great for capturing high-intent users actively searching for your product or service. If precision and keyword-level targeting matter most, Search is the way to go.

PMax vs. Demand Gen

While Performance Max is built to drive conversions across the entire Google network, Demand Gen focuses on creating visual-first campaigns that build interest and awareness in the upper funnel.

Demand Gen lets you use carousels, videos, and images across platforms like YouTube and Gmail, targeting audiences more like social media ads. If you're looking to create demand with engaging creatives before pushing for conversions, Demand Gen offers the control and formats you need.

This table breaks it all down:

Why Use Performance Max Campaign

So now that you’ve seen how PMax stacks up against Search and Demand Gen, let’s dig into what actually makes it worth using:

1. Centralized Campaign Control

No more switching between separate Search campaigns, Display campaigns, and YouTube ads. PMax lets you manage everything through a single point, which saves your time and gives a clearer view of your advertising strategy.

2. Data-Led AI Optimization

Google’s advanced machine learning models continuously test and adjust your bidding strategy, placements, and asset combinations in real time. The result is a better use of your advertising budget without constant manual changes.

3. Targeted Performance Strategy

With tools like Audience Signals, Customer Match, and custom segments, you can steer PMax toward your ideal audience. This is similar to feeding the system meaningful data that shapes how your ads are delivered.

4. Omnichannel Presence

PMax helps you meet users where they already are, whether they're watching videos on YouTube, checking directions on Google Maps, or scrolling through Gmail. This wider presence boosts visibility and keeps your brand top-of-mind across the full customer journey.

5. In-Depth Performance Reporting

Even though PMax automates delivery, you still have access to detailed campaign performance data, which lets you:

• Review top-performing asset groups
• Track conversion values
• Analyze which creative assets or audience signals are driving results

6. Attracts High-Value Customers

PMax looks for users who are likely to take valuable actions, like:

• Completing a purchase
• Signing up
• Filling a form
• Calling your business

It picks up on behavior signals and past conversion data to focus your ads on those who are more likely to convert, not just browse. This smarter targeting is what helped advertisers see a 22% increase in conversions and a 20% decrease in CPA with Performance Max.

7. Keeps Your Creatives Fresh Automatically

Thanks to PMax, you don’t need to constantly swap out ads to avoid fatigue. It mixes and matches your images, videos, and headlines to create the best-performing combinations tailored for each user.

What are Performance Max Assets?

Now that you know what makes the campaign so effective, let’s look at what powers it behind the scenes: your PMax assets.

Follow these PMax asset requirements closely, so your ads show up polished, relevant, and ready to perform:

Display URL: Keep each URL path under 15 characters. Add 1 to 2 variations to give Google some room to test which one performs best.

Headlines: Start with 3 to 5 short headlines under 30 characters. At least one should be of 15 characters or fewer to keep things punchy. You can also add up to 5 long headlines, each with a 90-character limit.

Descriptions: Keep each description under 90 characters, and include at least one that’s shorter than 60. Aim for 4 in total, but anywhere between 2 and 5 works.

Business name and logo: Stick to one clear business name, with max 25 characters. For logos, you can upload up to 5 files. To stay on-brand across placements, Google also lets you set custom colors and select a preferred font.

CTA: You can go with Google’s automated CTA or choose your own from a preset list. Just one clear CTA is needed, which must be aligned with your campaign objectives.

How to Set Up Google Performance Max Campaigns? 5 Simple Steps

Let’s see how you can set up your Google Performance Max campaign step by step to improve reach and results.

1. Set Clear Campaign Goals

Begin by identifying your main objective, whether it's boosting conversions, driving sales, or capturing leads.

Consider the exact action you want users to take, such as making a purchase, subscribing to a newsletter, or submitting a contact form.

Having clear goals helps Performance Max focus on what matters most by automatically adjusting bids and placements to deliver the best results.

To ensure accurate tracking and optimization, make sure these conversion actions are properly set up in your Google Ads account.

2. Choose Campaign Type and Assign a Name

Choose "Performance Max" as your campaign type to take advantage of Google’s full range of ad placements within one campaign.

Give your campaign a clear, goal-oriented name such as “Holiday Sales” or “Q4 Lead Generation” to make tracking and performance comparisons easier down the line.

3. Set Your Bidding Strategy
Choose a bidding strategy that aligns with your campaign goals:

• Maximize conversions: This option aims to generate the highest number of conversions within your set budget.
• Target ROAS: This option focuses on achieving a specific return on ad spend. For example, if you want to earn $4 for every $1 spent, set your Target ROAS to 400%.

4. Define Language and Location Targeting

Choose the languages and locations that best match your target audience. For local outreach, focus on specific cities or regions where your offerings are available. For wider campaigns, select broader geographic areas to increase visibility.

Accurate targeting helps ensure your ads reach users who are most likely to interact with them.

5. Set Your Budget

Determine a daily budget that fits your comfort level, keeping it flexible for adjustments as performance data comes in. Start with a reasonable amount, and scale up as needed.

Performance Max automatically allocates your budget across Google’s networks based on what’s performing best in real time, helping you get the most value.

Pro tip: Increase your budget during peak times, such as holidays or promotional events, to maximize reach and capture more leads or sales.

When to Use Performance Max?

Now that you know how to set up a Google Performance Max campaign, the next question is, when should you actually use it?

Let’s see when it makes the most sense:

• Your goal is to drive conversions like sales, leads, or calls
• You want to advertise across all Google channels with one campaign
• Automation and smart bidding fit your strategy
• Search campaigns feel limited, and you need a broader reach
• You prefer streamlined campaign management over multiple setups

Best Practices For PMax

Once your campaign is up and running, it’s easy to assume the automation will handle everything. But how well PMax performs still depends on the way you guide it.

We have shared some solid tips to keep your campaign sharp, focused, and actually working toward your goals:

1. Track Conversions Accurately

PMax makes decisions based on the conversion data you provide. If that data is off, your results will be too.

Follow these steps to stay on track:

• Go into your Google Ads account and double-check that the right conversion actions are selected (e.g., purchases, lead forms, page views, etc.).

• Alt tag: Google Ads conversion actions
• Source
• Set up enhanced conversions or import offline conversions through Google Analytics if you're working with leads.
• Google Ads Tutorials: Enhanced Conversions
• Verify that you're using the correct attribution model, ideally data-driven attribution, especially if you rely on Target ROAS or Maximize Conversions.

2. Leverage Audience Signals

While PMax finds users automatically, giving it a head start helps. Upload Customer Lists using Customer Match, create custom segments based on intent or interests, and include remarketing lists if you have them.

Head to your asset group settings, and add these under "Audience Signals." This way, you’re giving Google clues about who your ideal audience looks like.

3. Incorporate Videos

If you skip uploading a video, Google will auto-generate one, and let’s be honest, the results rarely do your brand justice. Thus, upload short, high-quality video assets (even 15-second explainer or product demo clips work) directly to the asset group.

This gives you more creative control, expands your reach across YouTube placements, and helps improve click-through rates. Nearly 9 out of 10 marketers say video delivers a solid ROI, which shows how effective it can be for driving performance.

4. Streamline Link Expansion

PMax’s final URL expansion can automatically send users to landing pages it thinks are most relevant. But it doesn’t always match your goals.

To stay in control, check your campaign settings to see which URLs are being used. If traffic is going to low-performing or off-target pages, either disable the feature or add exclusions.

For example, if you’re promoting a specific product but PMax keeps directing users to a general category page, you can exclude that URL to keep traffic focused.

5. Align Your Bidding Strategy with the Most Relevant Goals

Start by defining your goal: do you want more conversions, or more revenue from each one?

Start with Maximize Conversions if you're focused on lead generation. According to a survey, 45% of advertisers prefer it to drive higher volume at a lower CPA. But if you're selling products and tracking revenue, Maximize Conversion Value is the smarter pick. It’s favored by 55% of marketers thanks to its stronger ROAS, better CPCs, and higher CTR.

Once you have enough conversion data, you can fine-tune your strategy further using Target CPA or Target ROAS to align with your specific campaign goals. Make sure to check performance weekly to adjust your targets as needed.

6. Use Brand Terms as Negatives to Avoid Overlap

Already bidding on branded terms in your Search campaigns?

Exclude them from PMax to avoid overlap. For example, if “Acme Shoes” is one of your keywords, you can add it as a negative to avoid overlap. So the campaign focuses on reaching users who haven’t found your brand yet, instead of chasing the same traffic twice.

Since PMax doesn’t support keyword-level negatives by default, you’ll need to request exclusions through your Google Ads rep or use account-level negative keyword lists.

7. Refresh Creatives Regularly

Even the best-performing asset combinations won’t stay effective forever. Over time, users start seeing the same visuals and messaging, which leads to ad fatigue and lower engagement.

To avoid this, check the “Combinations” and “Assets” tabs in your campaign dashboard to spot what’s losing traction. Then, swap in new image assets, update headlines, and test fresh versions of your ad copy every 4 to 6 weeks.

This keeps your campaign relevant and aligned with shifts in user behavior or seasonal trends.

Common PMax Challenges

Even with all the right strategies in place, Performance Max isn’t without its challenges.

Before you dive in too deep, it’s worth knowing where things can get tricky, so you can plan ahead and avoid these common pitfalls:

1. Unpredictable Budget Allocation

Since PMax auto-allocates budget across channels, there’s no guarantee it will invest in the platforms you value most. Sometimes, more of the budget goes toward YouTube or Display, even if Search or Shopping drives better ROI.

2. Minimal Keyword Control

Performance Max doesn’t allow manual keyword targeting or bidding, which is a challenge if you're used to optimizing around specific search queries. You’re relying on Google’s judgment, and that can feel like a black box.

3. Slow Learning

When your campaign doesn’t generate enough traffic or conversions, PMax can’t optimize effectively. A limited daily budget or low conversion volume means it takes longer for the system to learn what’s working. That delay can hold back performance in the early stages, which makes it harder to see results.
