How smart brands drive 2-3x ROAS lifts during tentpole events

While competitors fight over expensive Amazon sponsored ads during Prime Day and other peak shopping events, the smartest brands are capturing high-intent or new-to-brand shoppers where competition is lighter and costs are lower: offsite channels like Google, Meta, and TikTok.

Keep reading if you're:

  • A media practitioner responsible for driving revenue during tentpole events
  • An agency leader managing Prime Day or holiday shopping campaigns
  • A brand manager looking to move beyond margin-eroding discounts
  • A performance marketer seeking to fuel Amazon growth through offsite media

 

The hidden opportunity in tentpole events

During peak shopping moments, everyone floods Amazon with sponsored product ads. This creates a massive opportunity gap in offsite channels where CPMs are lower, reach is wider, and high-intent shoppers are actively researching before they buy.

Ampd's analysis of recent Prime Day events reveals the power of this strategy:

  • 141% lift in ROAS for Paid Social campaigns driving to Amazon
  • 221% lift in conversion rate for Paid Social campaigns driving to Amazon
  • 206% lift in ROAS for Paid Search campaigns driving to Amazon
  • 313% lift in conversion rate for Paid Search campaigns driving to Amazon
  • 28% lower CPCs when starting campaigns 14 days before peak events

Why offsite media wins during Prime Day

Extended shopping windows create early opportunities

Tentpole events don't happen in isolation. Shoppers begin planning, researching, and building wishlists weeks before. Starting offsite campaigns just 14 days early can capture much of this pre-event surge when search interest grows but competition remains moderate.

Competition density creates opportunity gaps

When every brand pours budget into Amazon native ads, offsite channels become less saturated. This means better ad placements, lower costs, and access to audiences beyond Amazon's ecosystem during peak intent periods.

Attribution reveals true impact

Sophisticated measurement shows how offsite touchpoints influence on-platform purchases, creating a powerful flywheel effect that extends far beyond individual events.

The four-phase tentpole strategy

Pre-event phase (4-14 weeks out)

Focus on foundation building and momentum creation. Allocate 30-45% of total spend for discovery and audience building. Key activities include developing event-specific creative assets, building retargeting audiences, and optimizing Amazon landing pages for incoming traffic.

Launch phase (1-4 weeks out)

Shift to momentum building with teaser campaigns and anticipation content. Increase spend to 25-30% of the total budget. Test product selection and sequential messaging while monitoring competitor activity.

Peak phase (event week)

Deploy maximum conversion focus with 15-20% of total spend. Update creative to reflect live event status, implement aggressive retargeting, and optimize budgets during peak hours (12-2 PM, 7-9 PM).

Post-event phase (1-7 weeks after)

Capture extended value with 10-20% of remaining spend. Target late-decision shoppers, build loyalty loops with purchasers, and analyze performance data for future optimization.

Ampd customer case study: 156% sales velocity increase

One of Ampd's leading consumer packaged goods clients implemented our comprehensive tentpole strategy during a recent Prime Day event. By starting their offsite campaigns 3 weeks early with teaser content and scaling through our recommended budget allocation, they achieved:

  • 156% increase in Amazon sales velocity during the event period
  • 43% lower cost per conversion compared to Amazon-only campaigns
  • 2.3x higher new-to-brand customer acquisition through offsite touchpoints
  • Sustained 28% improvement in organic rankings for 6+ weeks post-event

The key was Ampd's agentic AI platform providing retail attribution data, allowing the brand to optimize budgets and creative in-flight while maintaining clear visibility into which offsite touchpoints were driving actual Amazon conversions.

Transform seasonal spikes into year-round growth

The data is clear: while competitors fight over expensive on-platform real estate, smart brands capture high-intent shoppers at the beginning of their purchase journey through sophisticated offsite media strategies.

Success during tentpole events demands the right technology, strategy, and execution. The most successful brands connect every offsite touchpoint to actual retail outcomes, optimize in real-time, and scale with confidence.
