Performance Max is a campaign type inside Google Ads that automatically places your ads across all of Google’s networks. Instead of choosing just Search or Shopping, your ads can appear across all of Google’s channels, including YouTube, Gmail, Discover, Display, and even Google Maps when linked with location assets.
Here’s how it works: you upload a bunch of assets like headlines, images, videos, and even product feeds. Google’s AI then mixes and matches these assets to create ads tailored to each placement. Someone browsing YouTube might see a video ad, while someone searching on Google might see a text ad. The system decides what version to show, where to show it, and how much to bid for that spot.
On the surface, this seems like a dream for time-poor businesses. Instead of juggling multiple campaigns, you run one. But if you’ve ever been involved in managing Google Ad campaigns in Australia, you know that there’s more to it than meets the eye.
How Do Performance Max Campaigns Actually Work?
You don’t build keyword lists like in a standard Search campaign. Instead, you set your goals, add assets, and provide audience signals. You can also add Search themes (word/phrase hints) to guide the system toward relevant queries, and you can add negative keywords (plus optional brand exclusions) to block unwanted searches. Google’s algorithm then optimises bidding and placements across Search, YouTube, Display, Discover, Gmail, and Maps.
The campaign then runs across Search, Shopping, YouTube, Display, Discover, Gmail, and Maps all at once. That’s a massive reach. Google combines user signals like intent, demographics, and behaviour to decide where your ad should appear.
Let’s say you run an online clothing store. You upload product images, a few videos of your clothing line, and descriptions. Performance Max takes these and generates ads that could show up in a teenager’s YouTube video stream, inside Gmail promotions, or even in a Maps listing for local shopping.
But then, know this: because Google decides where your ads run, you lose a lot of visibility. Unlike Standard Shopping or Search campaigns, where you can see exactly which keywords or placements are performing, with Performance Max, you’re left with much more limited insights than other campaign types.
The Benefits of Performance Max
Performance Max comes with a few clear advantages. Here are a few:
Reach
With one campaign, you can advertise across all of Google’s platforms. That’s exposure most businesses could never manage manually.
Automation
Google’s machine learning is designed to maximise conversions or conversion value in real-time. If you’ve got a solid flow of conversions coming in, Performance Max can take that data and find even more customers who look like your existing buyers.
Reduced campaign management
If you don’t have the time or expertise to constantly tweak campaigns, Performance Max takes a lot of that workload off your plate.
This makes it especially appealing to smaller businesses that aren’t ready to hire a full in-house team or a digital marketing agency from Sydney to do the heavy lifting.
Optimising Budget
Google works to show your ads to the right people at the right time. This helps you get better results without spending money on people who aren’t interested.
The Downsides of Performance Max
There is also a list of downsides involved:
Lack of transparency
Performance Max is often described as a black box because Google doesn’t show you exactly where your ads are running or how your budget is being allocated. You can see impressions and clicks, but not the detailed breakdown you’d get from other campaign types.
Less control over targeting
You don’t pick keywords; you can only hint with Search themes and steer with negative keywords (which only affect Search & Shopping), plus optional brand exclusions.
Cannibalisation
Because Performance Max runs across Search as well, it often competes with your other Search campaigns.
If you’re running branded keyword campaigns, Performance Max can steal credit for those conversions, making it harder to measure true incremental performance.
Limited Visibility
The limited visibility into placements means you don’t always know which websites your Display or YouTube ads are appearing on. For businesses that care about brand safety or very specific targeting, this lack of control can be a real problem.
Automation can send traffic to the “wrong” pages
Final URL expansion (on by default) can swap your landing page; text customization (formerly “automatically created assets”) can generate copy you didn’t write. Both can be turned off or constrained with URL exclusions/page feeds.
Who Should Use Performance Max?
Performance Max isn’t for everyone. Performance Max relies on consistent data to optimise, so campaigns with very small budgets often struggle. While there’s no strict minimum, a higher budget generally gives Google’s algorithm more room to learn and perform.
It’s also not a good idea if you’re brand new to Google Ads. If you’re a beginner, you would get more from structured campaigns like Search, Display or Standard Shopping, where you can learn the basics and maintain full control.
Furthermore, Performance Max works best for businesses that have a larger budget and generate steady conversions (ideally 20 to 50 – or more) each month. That way, Google’s machine learning has enough data to optimise effectively. If you’ve got those foundations in place, Performance Max can help you scale your results.
And if you’re running a business that also needs custom website development, Performance Max can tie directly into your eCommerce site to showcase products dynamically across Shopping, Display, and YouTube.
This can be particularly powerful when your website is optimised to capture leads or sales effectively.
How to Get Started With Performance Max
Here’s how you actually get started with Performance Max:
Campaign name & website URL, and settings
Name it something clear and enter your website. After that, pick where your ads will show, which languages people speak, the times of day your ads appear, which devices to show them on, and any brands you want to avoid showing with.
Add Your Assets
You would have to upload photos, videos, headlines, logos, and even product info. The more you show, the easier it is for people to understand what you’re offering and get interested.
Create Asset Groups
Group your pictures, videos, and headlines by theme or audience. For example, you could have one group for people seeing your ad for the first time, and another could be for people who have already visited your website. Grouping your assets helps Google decide which ad to show to which people.
Give Audience Hints
You can tell Google who you want your ads to reach. Use your own customer lists, people who have visited your site before, or ideas from what people are searching for online. This helps your ads get smarter and more effective.
Launch and Watch
Check everything one last time, press publish, and then watch how your ads are doing over the next few weeks. Within this time, watch and monitor the metrics that have more success, and make necessary adjustments to make your ads work even better.
