5 Steps to Structure Shopping Campaigns for Retailers

By Corey Frankosky · Last Updated August 6, 2026

Google Shopping campaigns drive around 85% of retail search ad clicks and account for roughly 76% of retail search ad spend, so how you structure Shopping campaigns for retailers decides whether that spend turns into profit or waste. If you dump every product into one campaign, you confuse Google's bidding and pay to show products that never sell. This guide walks you through the exact structure I use: a clean product feed, products grouped by performance and margin, campaign priorities tied to search intent, the right bidding strategy, and negative keywords to cut the junk. Retailers who segment this way regularly see higher conversion value and lower wasted spend.

1Why Campaign Structure Decides Your ROAS

Shopping ads do not run off keywords the way search ads do. They run off your product feed, and Google decides which products to show and how much to bid based on the data you give it. When Shopping campaigns underperform, the cause is almost always the feed and the structure, not the bids, the budgets, or the competition. That is good news, because both of those are things you control.

The core idea is simple. You segment your campaigns based on product performance, profit margins, and customer intent, and then you bid accordingly. Retailers who structure their campaigns this way can see up to 20% higher conversion value and roughly 18% higher click-through rates compared to a single catch-all campaign. Get the order right: feed quality first, structure second, bids third.

Question to Answer:

Are all of your products sitting in one campaign right now, or have you separated them so your best sellers get the budget they deserve?

2Step 1: Review and Improve Your Product Feed

Your product feed is the backbone of your Shopping campaigns. It dictates your placements and directly impacts performance. A well-maintained feed reduces disapprovals and makes you more competitive in the ad auction, which leads to higher Quality Scores and lower costs per click. Products with valid GTINs can see up to 40% more clicks, so pair accurate GTINs with correct pricing and high-quality images and you stop leaking spend before you touch a single bid.

Check Feed Accuracy

Start by making sure your product titles, descriptions, prices, and images match your website exactly. Any mismatch can get your Merchant Center account suspended, and that stops every campaign cold. Refresh your feed at least once every 24 hours so pricing and availability stay current.

Pay close attention to the id attribute. That ID carries the entire performance history for a product. If you change it, Google's algorithm has to start over from scratch. It is fine to retire a product you no longer sell, but otherwise keep those IDs stable.

Use Custom Labels for Segmentation

Custom labels (0 through 4) let you group products by profit margin, performance tier, or seasonality. Customers never see them. They exist purely to make your account easier to manage and to let you bid differently across groups of products. If you want to lean hard into your high-margin items, a custom label is how you isolate them. I recommend maintaining these through a supplemental feed, like a Google Sheet, that you update weekly.

Optimize Product Data for Search

Product titles are the main signal Google uses to match your ads to a search. Put the important details, brand, product type, and key attributes, in the first 70 to 100 characters. Instead of "Running Shoes," use "Nike Air Zoom Pegasus Men's Running Shoes - Black - Size 10." That version captures the high-intent, long-tail searches that actually convert.

3Step 2: Group Products by Performance and Margin

Not every product deserves the same budget. Putting everything into one campaign spreads your spend evenly across products that do not sell, and that alone can waste 30 to 60% of your budget. When you organize your catalog by performance tier and profit margin instead, you bid aggressively on the products that earn and pull back on the ones that do not. That shift can improve your overall ROAS by 10 to 30%.

Group by Best Sellers

Identify your top products using a four-tier system based on the last 30 days of data.

• Winners: The top 10 to 15% of products generating most of your revenue. Give these the highest budget.
• Risers: High-potential items closing in on your ROAS targets.
• Laggards: Items converting well below target ROAS. Reduce spend here right away.
• Sleepers: Products with low impressions. Test these carefully with a small budget.

Separate High-Margin and Low-Margin Products

Profit margin has to steer your strategy. Splitting products into margin groups can cut wasted spend by around 25%.

• High-margin products: Bid aggressively and aim for slightly lower ROAS targets to capture volume.
• Medium-margin products: Hold standard ROAS targets.
• Low-margin products: Set higher ROAS targets so you do not lose money on every sale.

Keep your Google Merchant Center feed updated as your costs change so these groups stay accurate.

Question to Answer:

Do you know which 10 to 15% of your products actually generate most of your revenue?

4Step 3: Set Campaign Priorities for the Customer Journey

Google Ads gives every Shopping campaign a priority setting: High, Medium, or Low. This is how you control which campaign bids on a given search query. The highest priority campaign bids first. If its budget is exhausted, the next priority takes over. You use this to line campaigns up with awareness, consideration, and conversion stages of the customer journey.

High Priority for Broad Discovery

Use High priority for low-intent, top-of-funnel searches like "running shoes." These shoppers are browsing. Set very low bids so you do not overpay, and add negative keywords to block your branded terms and push those searches down the funnel.

Medium Priority for Category and Branded Searches

Assign Medium priority to mid-funnel searches like "Nike running shoes." Use medium bids, and exclude specific product models with negative keywords so those exact-product queries fall through to your low priority campaign.

Low Priority for High-Intent Product Searches

Set Low priority for high-intent searches like "Nike Air Zoom Pegasus 40 size 10." These shoppers are ready to buy. Use aggressive bids here, and do not add negative keywords, because you want every bottom-of-funnel query landing in this campaign.

Question to Answer:

Which of your campaigns should be capturing your highest-intent product searches, and is it bidding aggressively enough?

5Step 4: Choose Bid Strategies and Allocate Budgets

Match your bid strategy to how much conversion data you have. New campaigns do not have enough history for automated bidding to work well, so you start manual and graduate to smart bidding once the data is there.

Select Your Bidding Strategy

• Manual CPC: Good for brand new campaigns where you want to gather initial data and keep tight control.
• Maximize Clicks: Useful for new products when you want to force some early traffic into the account.
• Target ROAS: Switch to this once you have 30 to 50 conversions in a month. Set your initial target about 10 to 20% below your real goal to ease the algorithm in.

Distribute Budgets Across Priorities

A good rule of thumb is to put 60 to 70% of your daily budget toward your top-performing products. Watch the "Lost Impression Share (Budget)" column to see exactly which campaigns are capped and need more money.

Adjust Based on Performance Data

When you change ROAS targets, move in small increments of 10 to 30% and then wait a few days before judging the result. Do not make massive changes all at once, because you reset the algorithm's learning. If a campaign hits its budget cap early in the day and it is profitable, raise the budget.

Question to Answer:

Do you have at least 30 conversions a month yet, or are you still in the manual bidding phase?

6Step 5: Add Negative Keywords

Google's recommendations and the Ads Advisor will suggest changes, but you should not lean on them for this. Go into your Search Terms Report yourself and add negative keywords by hand. Shopping ads run off your feed, not exact keywords, so negatives are your only real defense against bad traffic.

Look for queries with high cost and zero conversions. Exclude informational searches, bargain hunters, and B2B terms. Doing this consistently cuts wasted spend by 20 to 40%.

7Track Multi-Channel Conversions

Shoppers rarely buy on their first click. They see your product, leave, compare, and come back later on a different device. If you only credit the last click, you will misjudge which campaigns actually drive sales. Switch to data-driven attribution so you can see how your ads influence the full path to purchase across desktop and mobile.

If you run a large catalog and want automation layered on top of this structure, our breakdown of Google Ads Performance Max covers where it fits alongside standard Shopping.

Question to Answer:

Is your account still on last-click attribution, or have you switched to a model that credits the whole journey?
