Targeting Methods

Once you’ve set up well-organized audience lists, it’s time to apply targeting strategies that can improve your campaign results.

Customer Retargeting

Customer Match helps you connect with your current customers by using their purchase history and engagement data to craft personalized campaigns.

• High-Value Customer CampaignsCreate exclusive campaigns for your top customers. Offer perks like special deals or early access to new products. Focus on those who’ve made multiple purchases or have a high average order value. Segment these customers based on factors like purchase frequency, lifetime value, order size, or product category.
• Cart Abandonment RecoveryRe-engage shoppers who left items in their carts with dynamic remarketing ads. Highlight the abandoned items, suggest similar products, or include incentives such as limited-time discounts or free shipping to encourage them to complete their purchase.

You can also use product recommendations to keep customers engaged.

Product Recommendations

Product recommendations are a great way to encourage cross-sells and upsells. By analyzing purchase history, you can suggest items that complement what customers have already bought. For instance, if someone purchases a smartphone, you could promote accessories like cases, screen protectors, or wireless chargers.

Tailor these recommendations to seasonal trends or past buying habits. For example, offer gift ideas for the holidays, showcase summer collections, highlight back-to-school essentials, or suggest items for special occasions.

Similar Audience Expansion

Similar Audiences let you reach new prospects who share traits with your current customers. Start by using lists of high-value customers as a foundation. Build category-specific Similar Audiences, refresh your lists regularly, and test different look-back windows to see what works best. This approach helps you connect with audiences likely to be interested in your products.

Advanced Tactics

Take your Customer Match strategy to the next level with focused segmentation, cross-channel integration, and smart bid adjustments.

List Segmentation

Break your customer lists into smaller, targeted groups based on their behavior and value:

• Purchase Value Tiers: Group customers by lifetime value or average order size.
• Purchase Frequency: Separate one-time buyers from repeat customers.
• Category Affinity: Organize customers by their favorite product categories.
• Engagement Level: Use data like website activity, email interactions, and recent purchases to create engagement-based segments.

By combining these criteria, you can build highly targeted audience groups. Use these lists across all your channels to ensure consistent and personalized messaging.

Multi-Channel Integration

Maximize Customer Match by using it across multiple Google Ads channels:

• Search Campaigns: Tailor bids and ad copy for different customer segments.
• YouTube Ads: Engage current customers with product tutorials or branded content.
• Display Network: Deliver personalized banners featuring relevant products.
• Gmail Ads: Send targeted promotional messages directly to inboxes.

This approach ensures your message reaches your audience wherever they are.

Bid Management

Fine-tune your bidding strategy for better results:

Segment-Based Bidding and Real-Time Adjustments

• Raise bids for high-value customer segments to maximize ROI.
• Adjust bids based on time of day, device usage, and location.
• Factor in seasonal trends to stay competitive.

Performance Testing

• Experiment with different bid strategies using controlled tests.
• Keep an eye on metrics like ROAS, conversion rates, and cost per acquisition.

These tactics help you stay agile and improve campaign performance over time.
