How I Approach Google Shopping: Setup to Search Query Bidding

Much of the framework below builds on what I learned from Store Growers' Google Shopping Success and Performance Max Impact video courses. I've adapted their approach based on how I actually run accounts, but credit for the underlying structure goes to their training.

Google Shopping campaigns can look deceptively simple from the outside — a product feed, a bid, and you're live. In reality, the advertisers who consistently win are the ones who treat it as a system with two distinct phases: getting the foundation right, and then continuously refining how spend is allocated once traffic starts flowing in. Here's how I work through both.

Phase 1: Getting the Foundation Right

Before a single bid gets optimized, the groundwork has to be solid. I run through a structured checklist that covers four areas:

Your Store
Everything starts with the product data itself. That means accurate product information and images in the store's back-end, plus the operational details customers (and Google) expect to see clearly: contact information, shipping policies, and returns/refund terms.

Google Merchant Center
This is where the product feed comes to life. My process here is:

• Create and verify the Google Merchant Center (GMC) account, including domain claims
• Configure shipping and tax settings (tax being US-specific)
• Build the product feed — ideally through a plugin, app, or extension rather than fully manual work, though manual export, Google Sheets, or a dedicated feed management tool are all valid fallback options
• Upload the feed, then immediately check the Diagnostics tab to catch and fix errors before they quietly cap performance

Google Ads
Once the feed is clean, I connect it to the advertising side: creating the Google Ads account, installing conversion tracking, linking GMC to Ads, and uploading a customer list to unlock audience signals.

Google Remarketing
Finally, I lay the groundwork for remarketing — adding the Google Ads tag, confirming dynamic remarketing parameters are firing correctly, and building out additional audiences inside Google Ads for future targeting.

Skipping or rushing any one of these steps tends to surface later as a mysterious performance issue, so I treat this checklist as non-negotiable before moving to optimization.

Phase 2: Search Query Level Bidding

Once the account is live and generating search query data, the real optimization work begins. This is where campaign structure and bid strategy make or break efficiency. I typically choose between a 2-level or 3-level structure depending on account complexity.

2-Level Structure

Brand / Non-brand split:

• Campaign #1 (Branded queries): Low priority, high bids, no negative keywords
• Campaign #2 (Everything else): Medium priority, lower bids, brand terms added as negatives

Detail / Other split:

• Campaign #1 (Detail queries): Low priority, high bids, no negatives
• Campaign #2 (Everything else): Medium priority, lower bids, with identified "detail" (often longer-tail) keywords excluded

3-Level Structure

When there's enough volume to justify more granularity, I layer in a third tier:

Product / Brand / Non-brand:

• Campaign #1 (Product queries): Low priority, high bids, no negatives
• Campaign #2 (Branded queries): Medium priority, lower bids, brand terms negated
• Campaign #3 (Everything else): High priority, lowest bids, both product and brand terms excluded

Brand / Detail / Other:

• Campaign #1 (Branded queries): Low priority, high bids, no negatives
• Campaign #2 (Detail queries): Medium priority, lower bids, brand terms negated
• Campaign #3 (Everything else): High priority, lowest bids, brand and detail terms excluded

The logic underneath all of these structures is the same: the more specific and high-intent the search query, the lower the campaign priority and the higher the bid — because you want that traffic to route through the most targeted campaign first. Priority increases and bids decrease as you move toward the catch-all campaign, so budget doesn't get siphoned away from your best-performing segments by broader match traffic.

Why This Two-Phase Approach Works

Treating setup and bidding as separate, sequenced phases keeps me from optimizing on top of a shaky foundation. A perfectly tiered bidding structure won't fix a feed full of errors, and a flawless feed won't compensate for a bidding structure that lets broad queries cannibalize brand budget. Getting both right, in order, is what turns Google Shopping from a spend center into a predictable growth channel.
