In this lecture, you’ll learn what product segmentation is, why it’s so important for success in Google Shopping campaigns, and how it helps you identify and scale your most profitable products. Proper segmentation can be the difference between wasting ad spend on high-traffic, low-margin items and uncovering hidden winners that deliver strong returns.
What Is Product Segmentation?
Product segmentation means separating your products into different campaigns or ad groups to ensure each receives a fair share of your advertising budget. When all your products are lumped together in one campaign, Google’s algorithm tends to favor the ones with the highest search volume — meaning those products get most of the ad spend while others are overlooked.
Example:
Imagine you have two products:
- Product 1: 10,000–100,000 monthly searches
- Product 2: 1,000–10,000 monthly searches
Because Product 1 has a higher search volume, Google’s system will allocate most of your budget to it. As a result, Product 2 — even if it has a much higher conversion rate or profit margin — won’t get the visibility or clicks it deserves.
To fix this imbalance, you separate the products into different campaigns, each with its own budget. That way, both have an equal opportunity to perform and be evaluated on their own merits.
Why Product Segmentation Is So Important
Not all products are created equal. Some generate a large volume of clicks but bring in low profits, while others have smaller audiences but deliver much higher returns per sale. Product segmentation allows you to:
- Distribute ad spend fairly between products with different search volumes.
- Identify hidden profitable products that perform well when given their own budget.
- Scale effectively by allocating more budget to products with strong ROAS (Return on Ad Spend).
Example of Profit Difference
Let’s say:
- Campaign 1: Product with a $10 profit margin
- Campaign 2: Product with a $100 profit margin
Even though the second product may have less traffic, it only takes a few sales to achieve a great ROAS. But if these products share one budget, the low-margin product will consume most of it due to higher search volume. By segmenting, each product gets its fair share of ad spend, and you can easily identify which one performs best.
How to Segment Products Effectively
The first step in product segmentation is categorizing your products by search volume — typically high, medium, and low volume. You’ll determine this using keyword research data from tools like Google Keyword Planner (which you’ll learn to use in the next lecture).
Example Scenario:
Suppose you sell different types of glasses. Here’s what you find:
- Blue Light Blocking Glasses: 10,000–100,000 searches/month
- 3D Glasses: 10,000–100,000 searches/month
- Polaroid Glasses: 1,000–10,000 searches/month
Since Polaroid Glasses have significantly fewer searches, they should be placed in their own low-volume campaign, while the other two can stay in a medium- or high-volume campaign.
Step-by-Step: Organizing Your Product Segments
To organize your segmentation plan, use a simple spreadsheet structure. Create columns for Category, Product Name, and Search Volume. Here’s what it might look like:
| Category | Product | Search Volume |
|---|---|---|
| Keyboards | Wireless Keyboard | 10,000–100,000 |
| Keyboards | Mechanical Keyboard | 1,000–10,000 |
| Audio | Bluetooth Headset | 10,000–100,000 |
Once you’ve identified the volumes, group your campaigns as follows:
- High Volume Campaign: Popular products with lots of searches
- Medium Volume Campaign: Steady performers with moderate demand
- Low Volume Campaign: Niche or high-profit products with fewer searches
Example: Applying Segmentation to a Brand (Logitech)
Let’s revisit the example of a brand like Logitech. Suppose they sell categories such as:
- Mice
- Keyboards
- Webcams
- Audio Equipment
Each category contains multiple products, each with different search volumes. You would divide them into separate campaigns based on volume tiers — for example:
- High Volume: “Wireless Mouse,” “Gaming Keyboard”
- Medium Volume: “Ergonomic Mouse,” “Compact Keyboard”
- Low Volume: “Conference Webcam,” “Studio Microphone”
This structure ensures that low-volume, high-profit items don’t get buried under the weight of high-volume products consuming all the ad spend.
Best Practice: Copy, Don’t Create New Campaigns
When segmenting your existing campaigns, never create a brand new campaign from scratch. Instead, duplicate your existing campaign. This preserves all the valuable historical data that Google’s algorithm has already gathered, which helps maintain performance and speeds up learning in your new segmented campaigns.
Once you’ve duplicated, you can adjust each campaign’s products and budgets according to their search volume tiers.
Key Takeaways
- Product segmentation ensures fair ad spend and gives every product a chance to perform.
- Group products by search volume (high, medium, low).
- Use segmentation to discover hidden profitable products that may have lower traffic but higher margins.
- Always duplicate existing campaigns instead of starting new ones to retain performance data.
- Apply segmentation even if you have only a few products with differing search volumes.
Next Step: Keyword Research and Search Volume Analysis
Now that you understand the concept of product segmentation and why it’s crucial for scaling your store, it’s time to learn how to find those search volumes and organize your campaigns accordingly. In the next lecture, we’ll dive into Google’s Keyword Planner and show you exactly how to research and categorize your products for maximum profitability.
