Key Takeaways
- – The advantage of adopting Performance Max alongside Search campaigns is that it uses AI to drive conversions across the entire Google ecosystem.
- – Performance Max serves across Search, Shopping, YouTube, Display, Discover, Gmail and Maps from one campaign, using your conversion goal and target CPA or ROAS to bid.
- – Search campaigns retain priority for queries that match your eligible keywords, so Performance Max complements keyword coverage rather than cannibalising it.
- – Performance Max still depends heavily on accurate conversion tracking and strong creative assets, so treating it as a hands-off campaign with weak assets is the most common mistake.
Does Performance Max steal traffic from my existing Search campaigns?
No. If a search query matches an eligible keyword in your Search campaign, the Search campaign serves, regardless of Ad Rank. Performance Max only takes the query when there is no eligible matching keyword. That is why the two are recommended together rather than as alternatives.
What are audience signals in a Performance Max campaign?
Audience signals are the customer lists, custom segments, demographics and interest data you add to an asset group to tell the system who your likely converters are. They are hints, not targeting restrictions, so the campaign can still serve outside those groups if the signals point to a conversion. Adding your CRM lists and high value site visitors usually shortens the learning period noticeably.
Why does Performance Max need conversion tracking to work properly?
The bidding runs entirely on conversion data, so with no conversions or poorly configured tags the system has nothing to optimise towards. Set up conversion actions under Goals in Google Ads, mark the right ones as primary, and assign realistic conversion values if you plan to bid on target ROAS. Enhanced conversions and offline conversion imports help further when your sales cycle is long.
How do I see which channels Performance Max is spending on?
Open the campaign and check the Insights page, plus the Asset group and Listing group reports for asset level performance. Google does not give a full channel by channel spend breakdown, though the Insights page shows search category trends, audience insights and top performing assets. Use the Channel performance report where available and the asset performance ratings to decide what creative to replace.
