Once you’ve created your Google Merchant Center account and linked it to your eCommerce store, the next step is to set up your Google Shopping Campaign. This campaign type allows your products to appear directly in Google search results with images, prices, and store names — driving highly targeted traffic and boosting conversions.
In this guide, you’ll learn how to properly set up your Shopping Campaign in Google Ads, understand its structure, and plan your campaign organization for both small and large product catalogs.
Getting Started with Google Shopping Campaign Setup
Before diving into campaign structure, let’s complete the setup process.
Step 1: Create a New Shopping Campaign
In your Google Ads account, click on Create New Campaign. When asked for your campaign objective, select Sales. This ensures your campaign is optimized to generate purchases.
You’ll see a conversion goal labeled “Purchases.” This is exactly what we want. You may also notice a warning saying “Inactive Conversion Action.” Don’t worry—this doesn’t mean tracking isn’t working. It just means no sales have been recorded yet, so the conversion tag hasn’t fired.
Click Continue to move forward.
Step 2: Select the Shopping Campaign Type
Scroll down to select Shopping Campaign. Then verify that your Google Merchant Center account is correctly connected.
Next, you’ll be prompted to choose between two options: Performance Max and Standard Shopping Campaign.
Important: Choose Standard Shopping Campaign. This gives you greater control over your bidding, targeting, and product segmentation, which is ideal for optimizing performance and learning how Shopping Ads truly work.

Understanding the Structure of a Google Shopping Campaign
Before you set up your first ad, it’s crucial to understand how Google Shopping Campaigns are structured. A well-planned structure helps you control your ad spend, organize your products logically, and maximize ROI.
Campaign Structure Overview
A Shopping Campaign consists of three main layers:
- Account – Your main Google Ads account, where you define currency, time zone, and business information.
- Campaign – A container for related products or categories. Each campaign has its own budget and bidding strategy.
- Ad Group – A subdivision within the campaign, often based on product types or subcategories. Ad groups contain your product ads.
If you’re only selling a single product or niche (e.g., one line of sunglasses), your setup will be simple—just one campaign and one ad group. However, if you sell multiple categories or product lines, a more advanced structure is necessary.
Single Product or Small Niche: Simple Campaign Structure
For stores with one product or a single product line, the setup is straightforward:
- Create one Shopping Campaign.
- Inside it, create one Ad Group containing your single product (or closely related items).
- Let Google automatically pull the data from your Merchant Center feed.
This approach works best for smaller stores because all products share the same audience, targeting, and budget. You can easily manage and monitor performance within a single campaign.
Multi-Product Stores: Advanced Campaign Structure
If your store has multiple product categories and subcategories, you’ll want to use a more organized campaign structure. This ensures your products don’t compete with one another and allows you to set unique bids and budgets for each category.
Example: How to Structure Shopping Campaigns for Multiple Categories
Let’s use Nike as an example. Their online store includes several major product categories such as:
- Footwear
- Apparel
- Accessories
Each of these main categories should have its own Shopping Campaign. Then, within each campaign, you can create Ad Groups for the subcategories. For example:
Example Structure
- Campaign: Footwear
- Ad Group 1: Running Shoes
- Ad Group 2: Basketball Shoes
- Ad Group 3: Lifestyle Sneakers
- Campaign: Apparel
- Ad Group 1: T-Shirts
- Ad Group 2: Hoodies & Sweatshirts
- Ad Group 3: Training Pants
- Campaign: Accessories
- Ad Group 1: Bags & Backpacks
- Ad Group 2: Socks
- Ad Group 3: Hats & Headbands
This structure keeps similar products grouped together and ensures your ads don’t compete against each other within the same auction. Each product category has its own campaign, budget, and optimization strategy, which allows for better performance tracking and scaling.
Why Campaign Segmentation Matters
Segmenting your products into separate campaigns and ad groups allows you to:
- Allocate budgets more efficiently — Assign higher budgets to your best-performing categories.
- Improve targeting accuracy — Customize settings, keywords, and bids for each category.
- Prevent internal competition — Avoid your products bidding against each other for the same search terms.
- Gain clear performance insights — Understand which product types are driving the highest ROI.
In short, the more organized your structure, the more control you have over ad performance and profitability.
Planning Your Campaign Structure
Before you start building campaigns, analyze your website and product categories. Ask yourself:
- Do I sell one type of product or multiple types?
- Can I logically separate my items into categories and subcategories?
- Which categories deserve their own budgets or unique targeting?
Pro tip: Failing to plan is planning to fail. With Google Ads, structure is everything. Taking the time to organize your campaigns properly now will save you countless hours later and set you up for long-term success.
Example: Naming Your Campaigns Effectively
When creating campaigns, use a clear and consistent naming format so you can quickly identify their purpose and target.
Here’s a simple yet effective formula:
Objective + Product Category + Target Country
Examples:
- Sales – Running Shoes – US
- Sales – Training Apparel – UK
- Sales – Backpacks – CA
Since Google Ads already labels the campaign type (e.g., Shopping or Performance Max), the name should focus on your campaign’s objective and target.
What’s Next: Bidding and Budget Strategies
Now that you understand how to structure your Shopping Campaign, the next step is to learn how to manage bidding and budgets effectively. These strategies play a critical role in your overall performance and return on ad spend (ROAS).
In the next lesson, we’ll explore how to use Target ROAS (Return on Ad Spend) to maximize profit and scale your Shopping Campaigns efficiently.
