Shopping and Performance Max campaigns are the highest-ROAS Google Ads channels for most ecommerce brands.
Shopping and Performance Max campaigns are the highest-ROAS Google Ads channels for most ecommerce brands. System Strats builds PMax and Shopping campaigns with strong feed optimization, clean account structure, and asset strategies that work with Google's AI instead of against it.
Merchant Center feed optimization for ad eligibility
PMax campaign structure by margin and performance
Asset group strategy for creative variety
Conversion tracking with proper product-level attribution
We verify conversion tracking against the source of truth, fix broken events, implement Enhanced Conversions where needed, and rebuild reporting on solid data.
We audit and restructure campaigns, prune waste, add negatives, and fix ad copy and extensions that have not been touched in months.
We build the campaign structure that matches your goals, launch or relaunch campaigns, and monitor closely through the initial learning phase.
We run weekly optimization cycles on bids, audiences, creative, and search terms, and we report against real business KPIs on a monthly cadence.
We work across Search, Shopping, and Performance Max every day, and we treat conversion tracking as a first-class problem rather than something to check once at launch. We also know when to leave a campaign alone, which is as important as knowing when to change something.
Common questions about Google Ads Shopping & Performance Max, and how System Strats can help.
For most ecommerce brands, PMax is now the default for Shopping ads. Standard Shopping still has use cases for specific catalogs and control needs. We recommend the right approach based on catalog size and goals.
Clean Merchant Center feeds, strong creative assets (image and video), accurate conversion tracking, and enough budget to give the algorithm data to learn from. Most underperforming PMax accounts fail on one of these.
Yes, through feed segmentation with custom labels and campaign structure. We rarely run a single all-products PMax campaign because it is almost never the right answer.
It can happen without proper structure. We use negatives, account structure, and brand exclusions to prevent PMax from poaching traffic that would have come through brand Search anyway.
