Prime Day 2025 dates have officially been announced. The 4-Day Summer Event will take place July 8th – July 11th and planning is already in full swing. While many agencies promote extended “lead-in” and “lead-out” strategies to capitalize on the sales, the data tells a different story.
Our review of Summer 2024 Prime Day performance makes one thing clear: the majority of traffic and conversions occur only during the official Prime Day window. Despite the industry buzz, there was no measurable “halo effect” from early or post-event campaigns.
Key Takeaway: To maximize ROI and safeguard margins, concentrate your ad and promotional spend on the Prime Day core dates. Resist the temptation to spread your budget thin — timing matters, and so does precision.
