PD1

 Prime Day is one of Amazon’s largest global shopping events - often compared to Black Friday or Cyber Monday - and runs over two days (PD1 and PD2). It drives massive spikes in traffic, sales, and advertising activity across all categories.

How It Works:

• Timing: Prime Day usually takes place mid-year (June or July).
• Structure:
  • PD1 = Day 1 of the event (kickoff day).
  • PD2 = Day 2 (continuation and closing day).
• Deals are offered exclusively to Amazon Prime members and include Lightning Deals, Best Deals, and vouchers.
• Vendors and sellers prepare months in advance by submitting promotions, funding discounts, and increasing inventory to avoid stock-outs.

Benefits for Vendors:

• Massive sales uplift: Many brands see 2–5x daily sales vs. normal days.
• New customer acquisition: Exposure to millions of Prime shoppers.
• Brand visibility: High traffic drives long-term product ranking improvements.
• Cross-selling opportunities: Helps push complementary SKUs and new product launches.

Benefits for Amazon:

• Prime membership growth: Encourages sign-ups and renewals.
• Inventory turnover: Clears seasonal or older stock.
• Advertising revenue: Significant boost from Sponsored Ads and Brand Campaigns.

Challenges:

• Inventory pressure: Stockouts can lead to missed opportunities and ranking loss.
• High competition: CPC (cost per click) in ads spikes during PD.
• Strict deadlines: Vendors must submit deals and funding weeks in advance.

Why It Matters:
PD1 sets the tone for Prime Day performance. Strong results on Day 1 can boost sales momentum into PD2 and beyond. Amazon and vendors often compare PD1 YoY performance to evaluate Prime strategy effectiveness.

Example:
A home appliance brand participates in PD1 (July 16, 2025) with a 30% discount on air purifiers. Sales surge by +350% vs. previous week, and the ASIN maintains elevated ranking throughout Q3.

In short:
PD1 (Prime Day 1) is the first day of Amazon’s mid-year Prime Day event, a global sales peak that drives massive traffic, brand exposure, and revenue growth for participating vendors and sellers.
