A clean product feed first,
then Performance Max can actually learn
Performance Max is only as good as the feed and assets behind it. We have rebuilt feeds where a third of products were broken, by wrong prices or dead links, before a single campaign went live. No amount of bidding skill fixes a bad feed.
Where Performance Max quietly burns budget
Performance Max hides its mechanics behind automation, which means a broken feed or a missing exclusion list burns budget quietly instead of obviously. We have seen feeds where a third of products were disapproved for missing identifiers. We have seen prices in the feed that did not match the site. And we have seen campaigns spend against branded search terms that would have converted for free, organically.
Performance Max optimises across Search, Display, YouTube and Gmail at once. A mistake in the feed or the asset group does not just hurt one channel. It hurts the whole campaign’s ability to learn where your actual buyers are.
Performance Max automates so much of the targeting decision that the feed and the signals you feed it become the main levers left to pull. A well-run account spends most of its effort there, rather than fighting the automation. This is also why we treat the first few weeks as a deliberate learning phase, not a performance window. We resist the urge to change settings daily in response to normal early volatility.
What we fix in your account
- Feed audit. Every disapproval, missing identifier and price mismatch found and fixed, because the feed is the product the algorithm is actually selling.
- Asset groups built with intent. Grouped by category, margin or new-collection status, with images, headlines and descriptions written for the format, not pasted from a product page.
- Exclusions that protect what already works. Branded terms and existing customer lists get excluded or treated separately. That way Performance Max spends its budget finding new buyers, not rebuying your own brand searches.
- Signals fed deliberately. Customer match lists and conversion value rules set so the algorithm knows which customers and which conversions are worth more.
- Reporting split by value. New-customer acquisition tracked separately from repeat purchase, so you can judge the campaign on the metric that matters to your business.
What we need to start
- Access to Google Merchant Center and the Google Ads account.
- A product feed we can audit, either your platform’s native feed or a custom one.
- Clarity on your margin by product or category, if you want asset groups split by profitability.
- A customer list export if you want new-customer bidding, following Google’s data handling rules.
- Patience through the learning phase: Performance Max needs weeks, not days, to find its footing.
What you see in reporting
We report new-customer value separately from returning-customer value, since Performance Max’s own dashboard blends both unless you set it up correctly. Feed health is checked weekly: disapprovals, out-of-stock items showing as available, price mismatches. These are quiet failures. None shows up as a single alarming number, but together they add up.
Monthly reporting shows ROAS by asset group alongside the feed health score, so a dip in performance can be traced to a feed issue instead of guessed at.
We also watch the search term insights the campaign surfaces, since they reveal which queries Performance Max is actually matching your products against. That is useful for catching mismatches early. Where the mismatch traces back to a weak product title or missing attribute, we fix the feed directly rather than trying to compensate for it through exclusions alone.

FAQ
How much does this cost?
Launch starts from $1,000 for the feed audit and first campaigns. Monthly management starts from $1,200, depending on catalogue size and how many markets you sell in.
How long until we see results?
Launch takes about 2 weeks once the feed is clean. Performance Max typically needs 4 to 6 weeks to leave its automated learning phase and show a stable read. We explain this up front, so early weeks are not misread.
What ad budget do we need alongside this?
Feed-based campaigns need enough conversion volume to let the algorithm learn. That usually means at least $1,000 to $1,500 a month, for a single market catalogue of meaningful size.
What do you need from us?
We need Merchant Center and Ads access, and a feed we can audit. Margin or category data helps too, if you want asset groups split by profitability rather than treated as one catalogue.
How do you report on performance?
We report monthly ROAS by asset group, with feed health checks weekly. New-customer value is reported separately from repeat purchase, so the number reflects what the campaign is actually doing for your business.
