📈Why Segmentation Matters?

In today's highly competitive digital advertising environment, especially in e-commerce, basic campaign structures in Google Ads often fall short of achieving optimal performance. If you manage an e-commerce store with a diverse product catalog, you've likely noticed that the overall campaign performance view (such as average return on ad spend - ROAS) may seem satisfactory, but often masks significant inefficiencies and losses in specific product groups. This is where advanced product segmentation comes into play.

Limitations of Traditional Campaign Structures

Without detailed segmentation, your campaigns may suffer from several shortcomings:

• One-size-fits-all approach to diverse products: All products are managed by the same or similar rules and goals, despite their performance, margins, sales cycle, or seasonality potentially varying dramatically.

• Products with inefficient budget utilization: Some products may generate many clicks (and thus costs), but low conversion value or low ROAS, reducing the overall campaign efficiency. Without segmentation, it's difficult to identify these products and limit their promotion.

• Untapped potential of "star" products: Conversely, products with high ROAS and high conversion value may not receive sufficient space and budget to fully demonstrate their potential.

• Difficult bid optimization: Setting optimal bids (whether manual or automatic targets like tROAS) is complicated if the campaign contains products with very different profitability or conversion rates.

The Importance of Predictability and Consistency for Google AI

Modern Google Ads campaigns, especially those using automated bidding strategies (Smart Bidding) such as Target ROAS (tROAS) or Performance Max campaigns, rely heavily on Google's artificial intelligence (AI). For these algorithms to work as efficiently as possible, they need quality, structured, and above all, predictable data.

• Campaign predictability: Means that Google can reliably forecast how the campaign will behave – what will be the click-through rate (CTR), conversion rate, average order value, etc., if, for example, the budget or bid changes.

• Campaign consistency: If products in a campaign are grouped so that they have similar performance characteristics (e.g., similar ROAS, similar conversion value), the campaign becomes internally consistent.

How Does Karsa Labelizer Help Google AI? Karsa Labelizer creates highly consistent product clusters using AI. By "cleaning" campaigns of products with significantly different behaviors, it greatly increases their predictability. Google AI can then:

• More accurately estimate future performance: Leading to better bid setting.

• More efficiently allocate budget: Direct resources where there is the highest probability of achieving goals.

• Learn and adapt faster: More stable input data means faster and more efficient learning processes for Smart Bidding.

Benefits of Advanced Segmentation with Karsa Labelizer

Strategic product segmentation, which Karsa Labelizer automates and optimizes, brings a number of specific benefits:

1. Optimized budget allocation: Allows you to invest more in segments (clusters) with products that show the best results (e.g., high ROAS, high conv. value), and conversely, limit spending on segments with low performance or loss-making products.

2. More precise and efficient bidding strategies: Different product segments require different bidding strategies:

   • Best-performing products ("Bestsellers"): You can apply more assertive bids to maximize their visibility and sales volume.

   • Products with high conversion value: Strategies focused on profit maximization can be implemented (e.g., tROAS set to an appropriate value).

   • Low-performing or low-margin products: It is recommended to set more conservative bids, loss minimization strategies, or even pause these products.

   • New products: For products without a meaningful performance history, Karsa Labelizer offers flexible solutions. Instead of simple isolation, it allows either intelligent derivation of their likely performance and inclusion in existing clusters, or their temporary placement in a special campaign for data collection. This ensures detailed monitoring and the ability to set individual goals and budgets.

3. Increased overall efficiency and ROAS: The result is a demonstrable improvement in return on advertising investment in Google Shopping.

The Role of Segmentation in the Performance Max (PMax) Era

While Performance Max campaigns consolidate various Google advertising channels under one roof, they still strongly benefit from strategic product segmentation through signals from the product feed and targeting within asset groups. Quality data in the feed, enriched with meaningful Custom Labels (which Karsa Labelizer generates), are even more critical for properly directing Google's AI in PMax campaigns.

By creating thematically and performance-consistent product groups using Karsa Labelizer, you can more effectively structure your PMax campaigns and better align asset groups with specific product segments, leading to more relevant customer targeting and better results.

Using advanced segmentation through Karsa Labelizer thus goes beyond merely organizing products; it's a methodical approach to streamlining advertising investments and supporting growth goals in e-commerce.
