Feed-Based vs. Asset-Based (PMax)

What Does Feed-Based vs. Asset-Based Mean in PMax?

The distinction between feed-based and asset-based traffic in Performance Max is critical for campaign analysis: only with channel-level reporting can you tell whether your PMax campaign performs primarily through Shopping or through Display and YouTube. E-commerce businesses with a product feed and service providers without one need fundamentally different PMax strategies and optimization approaches.

In Performance Max (PMax) campaigns, Google distinguishes between two fundamental traffic types: feed-based and asset-based. This distinction is visible in channel-level reporting and is critical for understanding where your PMax performance comes from. Feed-based traffic is driven by your Merchant Center product feed; asset-based traffic is driven by the images, texts, and videos you provide.

Feed-based traffic is essentially what classic Shopping campaigns deliver: product ads in Google Search and the Shopping tab, driven by product data like title, price, and image. Asset-based traffic encompasses all other channels: Display, YouTube, Gmail, Discover, and text-based search ads. The performance of both types can differ significantly.

This distinction is central to your optimization. If the bulk of your PMax performance comes from feed-based traffic, you primarily benefit from your product feed. In that case, optimize the feed: better titles, higher-quality images, complete attributes. If performance comes more from asset-based traffic, your asset group signals and creative assets are the lever. Without this separation, you’re optimizing in the dark.
