Why Performance Max is Google Ads' new go-to campaign
Performance Max is now the campaign type Google pushes hardest for businesses that want to maximise conversions. Instead of creating lots of separate campaigns for Search, YouTube and Display, you run a single Performance Max campaign that automatically shows your ads across every Google channel. For business owners who are short on time, that sounds very tempting.
Full automation is not without risk, though. Without the right strategy and data, your budget can burn away with no direction. This article breaks down how it works, its strengths and weaknesses, and the optimisation tips that make every rupiah you spend on ads actually pay off.
What is Performance Max?
Performance Max is a goal-based Google Ads campaign type that lets one campaign appear across all of Google's inventory: Search, Display, YouTube, Discover, Gmail and Maps. You give Google your assets (text, images, video), audience signals and a conversion target; Google's AI system then handles placement, bidding and ad combinations automatically.
Unlike a classic Search campaign, which you control keyword by keyword, this campaign hands most decisions to the machine. That is why the quality of your assets and the accuracy of your conversion data decide whether the campaign succeeds. The approach suits businesses that want to reach more potential customers without managing many campaigns at once, provided the data foundations are in order from the start.
The data: where Indonesian digital ad spend is heading
Understanding market trends helps you give Performance Max the right place in your strategy:
- Digital advertising was projected to account for 75% of total ad spend in Indonesia in 2025, with the ad market worth US$6.4 billion (GroupM, 2025).
- 68.8% of digital ad spend goes through mobile devices, reflecting mobile-first consumers (Dentsu, 2025).
- The e-commerce sector contributes 22.5% of total ad spend, making it the biggest contributing vertical (Dentsu, 2025).
These figures make one thing clear: competition in digital advertising is getting tougher and relies more and more on automation. Performance Max sits right in the middle of that trend, but winning with it still takes smart human control.
How a Performance Max campaign works
So that you are not simply “handing everything to Google”, it helps to understand the three core components that shape the results.
1. Creative assets (asset groups)
You provide a set of headlines, descriptions, images, logos and videos, and Google assembles the best combination for each user. The more complete and the higher quality your assets, the wider your reach and the better the performance. Video assets matter a great deal because they open up YouTube's huge inventory.
2. Audience signals
Even though the campaign is automated, you can still give it “hints” in the form of customer data, interests and behaviour. These signals speed up machine learning so the campaign finds the right buyers sooner, especially in the early days after launch.
3. Smart Bidding and conversion data
This campaign works best when conversion tracking is accurate. That is why setting up tracking correctly has to come first; learn the basics with our Google Analytics 4 guide for beginners so the data reaching Google is clean and trustworthy.
The advantages of Performance Max for business
This campaign type offers some real benefits. First, broad reach from a single campaign, which saves management time. Second, automatic cross-channel optimisation that is hard to replicate by hand. Third, it is good at finding new audiences beyond the keywords you already target.
For businesses already running search ads, this campaign can be a complement that extends their reach. If you are just starting out, it is worth understanding the fundamentals in our Google Ads guide for Indonesian businesses before jumping into full automation.
When Performance Max is less suitable
Automation is not the answer to every situation. When a keyword in a Search campaign is identical to the user's query, Google gives the Search campaign priority over Performance Max, and Search campaigns give you tighter control over branded keywords. This automated campaign should therefore complement efficient branded Search campaigns rather than replace them.
PMax is also less than ideal if you have little conversion data, a very limited budget, or need tight control over where your ads appear. In those cases, it is wiser to run more controlled campaigns first, along with a strategy to stop Google Ads wasting your budget.
6 Performance Max optimisation tips
Here are practical steps to get the best performance from your campaign:
- Make sure conversion tracking is accurate before you launch any campaign.
- Fill every asset slot with a variety of headlines and images and at least one video.
- Use audience signals from your customer data to speed up machine learning.
- Use a product feed if you run an online store, so Performance Max shows relevant products.
- Separate brand and non-brand traffic so you can measure new conversions honestly.
- Allow learning time of at least 4-6 weeks before judging and adjusting your strategy.
Combining this campaign with other tactics, such as Google Ads remarketing, will strengthen your sales funnel from top to bottom.
Do not forget landing page quality
Even the best ad is wasted if the landing page is slow, confusing or not mobile-friendly. Remember, almost 69% of digital ad spend in Indonesia targets mobile devices, so the mobile experience decides conversions. Google's automated system also judges landing page quality when it optimises a campaign, and a poor page will push up your cost per conversion.
So before you increase your ad budget, make sure your landing page is fast, clear and has a strong call to action. A professionally designed website or landing page will turn more paid clicks into real sales, so your whole ad investment works more efficiently.
When should you bring in a professional?
PMax may be automated, but the initial set-up, asset quality and how you read the data still determine the results. If you want to avoid wasting budget during the learning period, working with an experienced team can help you hit your targets sooner. Webzoo helps businesses manage Google Ads campaigns end to end, from strategy and asset creation to conversion-focused Performance Max optimisation.
In the end, Performance Max is a very powerful tool when it is used with the right strategy. Automation handles the heavy lifting, but the direction, the data and the creativity still come from you, or from a partner who understands them.
