How This Playbook Helps You Beat Rising CACs

  • Mobile app advertising via Axon by AppLovin reaches over 1 billion users with 35 seconds of focused attention, bringing in incremental, high-value customers using your existing video creatives.
  • Gamified email popups and abandoned cart automation recover lost revenue and can lift conversions by up to 50% through interactive urgency.
  • User-generated content (UGC) galleries and AI-based personalization build trust and increase average order value (AOV) by about 15% with authentic content and dynamic recommendations.
  • Referral programs, one-click checkout, and tiered loyalty programs drive viral growth and repeat purchases while reducing cart abandonment.
  • Use Axon to diversify your media mix and scale return on ad spend (ROAS) with untapped mobile app audiences.

Who Should Use These Plays and How They Fit Together

These tactics serve two primary groups. Direct-to-consumer (DTC) founders want simple, proven ways to scale. Performance marketers need incremental ROAS as acquisition costs rise.

The 15 plays map to a simple customer journey. First, attract new visitors through mobile app advertising, prospecting, and influencers. Next, convert them with popups, UGC, personalization, and streamlined checkout. Then, retain and grow value with automation, loyalty, referrals, and bundling.

The strategies also align with the 7 C’s of e-Commerce: Context (UGC storytelling), Commerce (optimized checkout), Community (referral programs), Customization (AI-based personalization), Communication (live chat), Confidence (retargeting), and Centricity (loyalty programs). Start with quick wins such as abandoned cart automation, then layer in higher-investment tactics like new advertising channels.

1. Mobile App Advertising via Axon by AppLovin

Reach over 1 billion mobile app and game users and acquire new customers at scale.

Axon by AppLovin is an AI-based advertising platform that helps DTC and e-Commerce brands acquire new, high-value customers. It delivers ads across mobile apps and games with an average of 35 seconds of focused attention per Axon data, far longer than typical social feeds.

Start by uploading your existing 9×16 video creatives from social campaigns, so you avoid new production work. Then set ROAS or Cost Per Purchase (CPP) targets that match your profitability goals. Once campaigns are live, enable Prospecting campaigns to focus on new customers instead of retargeting existing ones. As results come in, adjust and scale budgets daily based on performance data. Finally, track incrementality through third-party attribution platforms to confirm that Axon drives truly new sales rather than shifting credit from other channels.

2. Gamified Email Popups That Turn Visitors Into Subscribers

Capture more emails by making your first touchpoint feel like a game, not a form.

Gamified popups that use spin wheels, scratch cards, or quiz elements can grow email lists faster than static offers, according to MonsterInsights. Kennedy Blue increased sales by 50% using popups that created urgency and excitement.

Design spin-to-win wheels that offer clear discount percentages instead of vague prizes. Add exit-intent popups with interactive elements to catch visitors before they leave. A/B test different game mechanics and reward structures to see what drives both signups and sales. Segment subscribers based on how they interacted with the popup. Follow up with personalized email sequences that reference the specific game or reward they engaged with.

3. Abandoned Cart Retargeting Automation That Recovers Revenue

Win back a meaningful share of the more than 70% of shoppers who abandon their carts.

Global cart abandonment rates exceed 70%, and mobile abandonment rates climb even higher. This high drop-off creates a large revenue opportunity. Abandoned cart recovery emails achieve strong open and conversion rates because they target shoppers who already showed clear purchase intent.

Set up automated email sequences that trigger at one hour, 24 hours, and 72 hours after abandonment. Include product images and personalized discount codes to remind shoppers what they left behind. Support these emails with retargeting ads on social channels such as Meta and Google. Use SMS for high-value abandoned carts where a faster, more direct touch makes sense. Add web push notifications for shoppers who opted in and are still browsing on desktop or mobile.

4. User-Generated Content Galleries That Build Trust

Show real customers using your products to increase confidence and conversions.

Product pages that feature verified UGC galleries can deliver higher conversions and longer dwell times according to CS-Cart. UGC-style ads often achieve 4x higher click-through rate (CTR) and 50% lower cost per click (CPC) than polished studio content.

Collect customer photos and videos through post-purchase email campaigns that ask for real-life shots. Build dedicated UGC galleries on product pages so shoppers can scroll through authentic examples. Incentivize submissions with discount codes or loyalty points. Repurpose strong UGC in paid advertising campaigns to extend its impact. Display real-time customer reviews and ratings alongside the gallery to reinforce social proof.

5. AI-Based Personalization That Lifts Average Order Value

Use behavioral data to show each shopper the products they are most likely to buy.

AI-based personalization addresses a core challenge: matching each visitor with the right products and offers. By analyzing browsing patterns and purchase history, these systems can increase AOV by about 15% through dynamic product recommendations, personalized email content, and behavioral targeting. Machine learning models study on-site behavior to predict preferences and improve product placement.

Implement dynamic product recommendation engines across home, product, and cart pages. Personalize email subject lines and content based on past purchases and browsing history. Use predictive analytics to guide inventory and pricing decisions so you stock and promote items with the highest expected demand. Deploy chatbots that provide personalized product suggestions during sessions. Create custom interactives tailored to different customer segments so each group sees relevant experiences.

Use Axon audiences to feed more high-intent shoppers into your personalization engine and amplify these gains.

6. Referral Programs That Turn Customers Into Promoters

Reward customers and their friends to create a steady stream of warm leads.

Glossier’s founder attributes 70% of the company’s online sales and traffic to peer-to-peer referrals that rely on user-generated content and reviews. Strong referral programs reward both the referrer and the referred customer, which encourages sharing and creates viral growth loops.

Design double-sided incentives so both parties receive clear value. Integrate referral tracking into customer accounts to keep the process simple. Promote the program through email, on-site banners, and social media posts. Track referral program return on investment (ROI) and customer lifetime value (LTV) from referred users. Adjust reward structures based on performance data to keep the program profitable.

7. One-Click Checkout That Removes Friction

Shorten the path to purchase so fewer shoppers drop off at the final step.

Streamlined checkout flows with guest options, multiple payment methods, and mobile-friendly layouts significantly improve conversion rates. Every extra field or step increases the chance of abandonment.

Enable guest checkout so shoppers can buy without creating an account. Integrate multiple payment options, including digital wallets, to match customer preferences. Minimize form fields and use auto-fill capabilities where possible. Display security badges and trust signals near payment fields. Optimize the entire checkout experience for mobile devices, since many shoppers complete purchases on phones.

8. Live Chat That Answers Questions Before Shoppers Bounce

Give visitors real-time support so they feel confident completing their order.

Live chat can increase conversion rates by up to 20% by resolving questions during the shopping process. AI-based chatbots handle common inquiries, while complex issues route to human agents who can close higher-value sales.

Deploy AI-based chatbots for 24/7 coverage of frequently asked questions. Train live chat agents on product details and basic sales techniques so they can recommend the right items. Use proactive chat triggers based on user behavior, such as long time on a product page. Integrate chat with customer relationship management (CRM) systems to support personalized interactions. Monitor chat metrics and customer satisfaction scores to refine scripts and staffing.

9. Advanced Prospecting Campaigns for New Audiences

Reach people who have never heard of your brand and turn them into first-time buyers.

Prospecting campaigns focus on new customer acquisition instead of retargeting existing visitors. They expand your total addressable audience and support long-term growth.

Set up lookalike audiences based on your highest-value customers. Use interest-based targeting to reach cold audiences that match your niche. Test different creative formats that speak directly to new prospects who lack brand familiarity. Implement clear attribution tracking so you can measure incremental impact from prospecting. Scale successful prospecting campaigns gradually while watching blended ROAS.

10. Dynamic Product Catalogs That Stay in Sync

Keep ads accurate and relevant with real-time product feeds.

Dynamic catalogs update product feeds in real time so ads always show current pricing and available inventory. This approach reduces wasted spend on out-of-stock items and keeps offers relevant for shoppers.

Connect your product feeds to your advertising platforms. Set up automated inventory updates so changes sync without manual work. Implement dynamic pricing rules based on demand or margin targets. Create product sets for different audience segments, such as bestsellers for new visitors and higher-margin items for returning customers. Monitor catalog performance and refine which products appear most often.

11. Tiered Loyalty Programs That Grow LTV

Reward repeat purchases with clear progression and status.

Paid membership program members are more likely to spend more with the brand than non-members. Tiered loyalty programs create a sense of progress that encourages customers to keep buying and unlock better perks.

Design multiple tiers with increasingly valuable benefits. Offer early access to sales and new products for members. Use a points-based reward system that feels simple and transparent. Create VIP experiences for top-tier members to deepen emotional connection. Track program ROI and engagement so you can refine benefits over time.

12. Email and SMS Automation That Nurtures Relationships

Stay in touch automatically so customers keep coming back.

Automated flows handle welcome series, post-purchase follow-ups, and re-engagement campaigns without constant manual work. These sequences keep your brand present and relevant.

Set up welcome email sequences that introduce your story and bestsellers to new subscribers. Create post-purchase automation that includes review requests and helpful product tips. Implement win-back campaigns for inactive customers with tailored offers. Use SMS for time-sensitive promotions and shipping updates where immediacy matters. Segment audiences so each group receives messages that match their behavior and value.

Feed your automation with fresh, high-intent traffic from Axon’s mobile app audiences to grow your retention funnel.

13. Nano-Influencer Partnerships for Authentic Reach

Work with smaller creators whose audiences actually listen to them.

Nano-influencers with roughly 1,000 to 10,000 followers often deliver higher engagement and more authentic connections than macro-influencers. Their recommendations feel personal, which can drive better conversion rates at lower costs.

Identify influencers in your niche who have engaged, relevant audiences. Offer product exchanges or modest payments that fit your budget. Provide clear brand guidelines while allowing creative freedom so content feels natural. Track performance through unique discount codes or links. Build long-term relationships with top performers instead of one-off posts.

14. Product Bundling Strategies That Lift Cart Size

Package complementary items so customers spend more while feeling they get a deal.

Strategic bundling can increase AOV by 20% to 30% while giving customers clear value through discounted packages. Bundles work well because they achieve several goals at once. They help move slower inventory, introduce shoppers to products they might not discover alone, and create a strong value perception that justifies a higher cart total.

Analyze purchase data to find products that customers frequently buy together. Create themed bundles for different segments, such as starter kits or seasonal sets. Offer bundle discounts that still protect your margins. Test different bundle combinations and price points to see what resonates. Promote bundles through email campaigns and social media content.

15. Diversified Media Mix Testing to Reduce Risk

Spread your ad budget so you are not exposed to a single algorithm or channel.

Testing emerging platforms such as AppLovin improves diversification and can reveal channels with stronger engagement and clearer incrementality. A diversified mix protects your brand from sudden performance drops on any one platform.

Allocate 10% to 20% of your ad budget to testing new channels. Run structured incrementality tests to measure each channel’s true impact on sales. Compare performance across different attribution models so you do not over-credit last-click sources. Scale channels that show strong, incremental results while keeping a balanced mix. Watch the competitive landscape for new inventory and formats that may offer early-mover advantages.

Implementation Challenges and How to Measure Results

Common Pitfalls to Avoid

The biggest mistake involves ignoring incrementality when testing new channels. Use measurement platforms such as Haus or Northbeam to confirm that new tactics drive additional sales instead of cannibalizing existing ones. Focus on blended metrics across channels instead of relying only on last-click attribution.

Metrics That Matter Most

Track ROAS, Cost Per Purchase, customer acquisition cost (CAC), and customer lifetime value across all channels. Monitor day-zero (D0) and day-seven (D7) purchase rates to separate immediate from delayed conversions. Aim for LTV to CAC ratios of at least 3:1 to support sustainable growth.

Frequently Asked Questions

How quickly can I start using Axon for mobile app advertising?

Axon signup usually takes less than an hour, and you can launch campaigns the same day using existing 9×16 video assets from social media. The platform integrates with Shopify through a simple installation and supports Google Tag Manager for comprehensive tracking. You receive performance data quickly, which supports fast scaling decisions.

How does Axon differ from social media advertising?

Axon delivers ads inside mobile apps and games, where users typically give longer, more focused attention than in social feeds. These audiences often include people who are less active on social channels such as Meta and Google, which helps you reach customers you might otherwise miss.

Which growth hacks usually provide the fastest ROI?

Abandoned cart automation and gamified email popups often show measurable results within about 30 days. UGC galleries can go live quickly if you already have customer content. Referral programs usually need 60 to 90 days to build momentum. Mobile app advertising through platforms such as Axon can scale quickly once you have strong creative assets.

How should I measure incrementality across multiple tactics?

Use holdout testing and marketing mix modeling to isolate each tactic’s true contribution. Platforms such as Haus support geo-lift testing, while attribution tools such as Northbeam track cross-channel performance. Focus on new customer acquisition rates and blended ROAS to understand incremental value rather than relying on last-click data.

What budget split works well for testing these strategies?

Many brands allocate about 70% of budget to proven channels, 20% to scaling successful tests, and 10% to new experiments. Start with lower-cost tactics such as email automation and UGC before committing larger budgets to paid channels. Test one new tactic at a time so you can clearly see its impact and avoid attribution confusion.
