Performance Max has a reputation as a black box, because spend used to be hard to trace by channel. Performance Max channel reporting changes that by showing where your campaign runs and how each channel contributes. This guide explains where to find the report, how to read it and what you can do with what you learn.

What the Channel Report Shows
Google’s help page on the channel performance report for Performance Max says it shows campaign performance across Google’s channels and how each one contributes to your conversion goals. The channels it lists are Google Search, the Display Network, YouTube, Discover, Maps, Gmail and Search partners.
The report has a performance summary, a chart that links channels to goals, a time series and a channel distribution table. The table is the most detailed view and includes a segment option and a status column.
Where to Find It
In Google Ads, go to Campaigns, open the Insights and reports menu and choose channel performance. The toolbar lets you segment and download the data. Google says date ranges are available for dates after 6 June 2025.
How to Read the Table
- Metrics. Impressions, clicks, interactions, conversions, conversion value, cost, results and results value, by channel.
- Segments. You can split by channel, ads that use product data, ads that use video, conversion category, conversion action and ad event type.
- Status. A channel can show as Not eligible, Eligible (limited), Eligible or Missing required assets, with diagnostics such as asset group policy problems, product feed issues, missing video assets or budget limits.
A channel with no ads and no issues may simply be one the system is not prioritising, because it expects better returns elsewhere.
What You Can and Cannot Control
You cannot set a budget for each channel. Google says that assets, audience signals, conversion tracking, search themes and exclusions can influence where spend goes, and that exclusions may reduce reach. That makes asset quality your main lever. Our guide to structuring Performance Max asset groups shows how to organise them.
Caveats Worth Remembering
- Attribution follows the model you set for each conversion action.
- Offline conversions at individual stores are summed in one total, so you cannot see them by channel.
- Image asset conversions can appear on channels other than Display.
- Significant changes can take one to two weeks to settle, so avoid reacting to a few days of data.
Turning the Report Into Action
- Check where results come from. If most conversions sit on one channel, review the assets that suit it.
- Look for missing assets. A status of missing required assets points to a fix you can make today.
- Review your goals. If the campaign chases low-value conversions, adjust the conversion actions it uses.
- Compare with other campaigns. Use our guide to Performance Max and Standard Shopping to decide where each type belongs.
Channel data also belongs in your regular reviews. Add it to the checks in our Google Ads audit checklist.
A Weekly Routine for Performance Max Channel Reporting
A short routine keeps the report useful. Once a week, open the channel table for the last full period and note which channels carry spend and conversions. Compare against the previous period to see whether the mix has shifted.
Then check the status column for each channel. If a channel shows missing assets, add them. If it shows a policy or feed issue, fix it. Write a one-line note on what you changed, because Google advises that significant changes can take a week or two to settle.
Finally, ask three questions. Do the channels getting the spend fit your customers? Are the conversions counted the ones that matter? Do the assets suit the channels where the budget goes? If any answer is no, adjust the assets or conversion goals rather than reacting to a single day’s numbers.
Pair the Report With Your Feed and Assets
Channel data tells you where the campaign shows up, and your inputs decide how well it performs there. If you sell products, review your product feed alongside the report, because feed problems can limit certain formats. If you rely on video, check that you have video assets, since Google’s status column can flag missing ones.
Use what you learn to brief creative work. If YouTube carries real spend, strong video matters. If Search carries most of it, headlines and search themes deserve extra care.
Share What You Find
Channel data is easy to explain to colleagues and clients, because it shows where the money goes. Include a short summary in your regular reports, with the main channels, any status issues and the action you took. That habit builds trust in the campaign and makes it easier to defend decisions about assets and goals.
Frequently Asked Questions
Can I stop Performance Max from showing on a channel?
There is no direct channel switch for budget. Google points to assets, audience signals, search themes and exclusions as the ways to influence delivery.
Why does a channel show no ads?
Google says that if a channel shows no ads and no issues, the campaign is likely prioritising channels with higher expected returns.
Final Thoughts
Performance Max channel reporting gives you the visibility that was missing at launch. Review it regularly, fix missing assets and judge the campaign on goals that match real business value.
