Boost your ROAS with feed-only Performance Max campaigns! Learn how minimal assets can drive better results by focusing ad spend on Google Shopping.
In this blog post, I'll explain how I structure Performance Max (PMax) "feed-only" campaigns, a strategy that has been driving impressive results for our clients. By focusing on minimal assets—using fewer images, ad copy, and no videos—we encourage Google to allocate more spending towards Google Shopping, where we consistently see the highest return on ad spend (ROAS). While this approach doesn't work for every campaign, we've found it highly effective when used alongside a full-asset PMax campaign. Let's dive into how it works and the results we've seen!
The concept of a feed-only PMax campaign is simple: you strip the campaign down to the essentials. That means:
The goal is to ensure most of your ad budget is spent on Google Shopping, where we consistently see the best return on ad spend (ROAS) for e-commerce clients.
This strategy isn't about cutting corners. Instead, it's a focused approach to driving traffic through the channel that performs best. Of course, we don't rely solely on feed-only campaigns—we typically run them alongside full-asset PMax campaigns to cover all our bases. But for certain products, feed-only can be a game-changer.
We ran three different types of campaigns for a single product that later expanded into a product group:
After spending around €200, the campaign that combined feed-only assets with audience signals came out on top. It consistently delivered the highest ROAS, confirming that this hybrid approach offers the best results.
Here's a breakdown of how we structure our feed-only PMax campaigns:
Minimal Assets:
Audience Signals and Search Themes:
Adding these helps Google identify the best audience for your product without you having to rely on display or video ads.
The goal is to provide Google with just enough to run Shopping ads while limiting its ability to display the campaign in other formats like search, YouTube, or display.
The key to success here is in controlling the ad spend. By limiting assets, you essentially "nudge" Google Ads to focus most of the budget on Shopping ads, where we've seen the best performance. Google might still spend a bit on other channels like search or video, but the bulk goes shopping.
We also use a PAC (Performance Max Allocation) Script to monitor where the money is being spent. This allows us to ensure that the majority of the budget is going where it should—towards Google Shopping.
Based on our tests, the campaign structured as "Feed-Only + Audience Signals" significantly outperformed the others. Here's what we found:
Feed-only PMax campaigns aren't a one-size-fits-all solution, but for many e-commerce businesses, they offer a highly effective way to maximize returns on Google Shopping. By keeping the asset count low and focusing on Shopping ads, you can improve performance without overcomplicating your campaigns.
