Rufus sponsored prompts go paid: CPC billing is live
Amazon moves Rufus Sponsored Prompts to general availability with CPC billing on March 25. All active SP and SB campaigns are auto-enrolled with no opt-out.
Antoine founded Nova Analytics to empower Amazon sellers with enterprise-grade analytics. He specializes in data architecture and building scalable solutions for e-commerce businesses.
Update - May 13, 2026: Amazon launched Alexa for Shopping, folding Rufus into Alexa+ across Amazon.com, the Shopping app, Alexa.com, the Alexa app and hundreds of millions of Echo devices. The same agent now carries one persistent shopper profile across every surface. The actions in this article still apply, but treat them as a baseline rather than a ceiling.
March 25, 2026: Amazon's Rufus Sponsored Prompts are now paid. CPC billing is live for all sellers with active Sponsored Products or Sponsored Brands campaigns. You're auto-enrolled. There's no opt-out. What the cockpit data tells us: the operational drag from announcements like this is concentrated in a small slice of SKUs.
What Changed on March 25
Two weeks ago, we reported that Amazon was running Rufus ad placements for free. That phase is over. On March 25, Amazon moved Sponsored Prompts to general availability with full CPC billing. If you have active Sponsored Products or Sponsored Brands campaigns, you're already paying for Rufus placements.
This is the first time sellers are paying for placement inside an AI conversation. It's not a traditional search result. It's not a product detail page banner. It's a sponsored follow-up question or product card embedded directly inside a Rufus answer. And it comes with a premium.

All active SP/SB campaigns are auto-enrolled
Early data from advertisers shows CPCs running 15-30% above standard Sponsored Products placements. But here's the tradeoff: conversion rates are 2-3x higher. Shoppers who engage with Rufus are further along in their purchase journey. They've asked specific questions, received AI-curated answers, and are clicking sponsored prompts with intent.
The Math Works (For Now)
A 20% CPC increase with 2.5x higher conversion means your effective cost-per-acquisition from Rufus placements is actually lower than standard SP. But this only holds if the conversion premium sustains as more advertisers compete for Rufus inventory.

The Budget Impact You Can't Ignore
Your Daily Budgets Will Drain Faster
With Rufus placements auto-enrolled and CPCs running higher, your existing campaign budgets will deplete faster than before. If you're running daily budget caps, you may see campaigns pausing earlier in the day. Monitor your budget pacing closely for the first 2-3 weeks.
Amazon hasn't provided a way to set separate bids for Rufus placements. Your existing SP and SB bids are used as-is. That means if you're bidding $2.50 on a keyword in Sponsored Products, you're also bidding approximately $2.50 for the same keyword when it surfaces inside a Rufus conversation, even though the CPC premium is applied on top.
Pro Tip: Track TACoS, Not Just ACoS
With Rufus adding a new, higher-converting (but more expensive) channel to your campaigns, TACoS is the better metric to watch. If your TACoS improves despite higher per-click costs, Rufus placements are working. If TACoS spikes, you may need to reduce overall bids to compensate.
What You Should Do Now
1.
Increase daily budgets by 15-20% as a buffer
Rufus clicks are now drawing from your existing budgets. If you don't increase caps, you'll lose impression share on traditional placements as Rufus consumes budget earlier in the day.
2.
Monitor the "Rufus" placement in campaign reports
Amazon has added a limited placement filter for Rufus in SP reporting. Check it daily for the first two weeks to understand your CPC and conversion patterns. Use PPC analytics to track changes.
3.
Optimize listing content for AI conversations
Rufus selects which products to show based on listing relevance to the conversation. Clear, benefit-focused copy in titles, bullets, and A+ Content increases your chances of appearing. Review our Rufus optimization guide for specifics.
4.
Model the impact on product-level profitability
Higher CPCs mean tighter margins on low-AOV products. Use product-level P&L to identify which SKUs can absorb the premium and which need bid reductions.
How Nova Helps
Rufus placements add a new variable to your PPC performance. Nova's PPC analytics track product-level PPC metrics daily, so you can isolate Rufus impact on spend, CPC, and conversion rates without manual spreadsheet work.
Combine PPC data with profit and loss tracking to see whether the Rufus CPC premium is eating into margins or driving enough incremental revenue to justify the cost. If you're managing multiple brands, multi-account analytics let you compare Rufus impact across portfolios.
Sponsored Prompts are paid ad placements inside Rufus AI shopping conversations. They appear as sponsored follow-up questions or product cards embedded in Rufus answers. Amazon selects which products to show based on relevance to the conversation and your existing SP/SB campaign targeting.
Rufus Sponsored Prompts use CPC billing with costs running 15-30% above standard Sponsored Products placements. There is no separate bidding mechanism. Your existing SP and SB bid levels are used. The premium is applied by Amazon based on the Rufus placement context.
No. As of March 25, 2026, all active Sponsored Products and Sponsored Brands campaigns are automatically enrolled in Rufus Sponsored Prompts. Amazon has not provided an opt-out mechanism. The only way to avoid Rufus placements is to pause your SP and SB campaigns entirely.
Rufus clicks draw from your existing campaign daily budgets. With CPCs running 15-30% higher, budgets deplete faster. Sellers should increase daily caps by 15-20% to maintain impression share on traditional placements. Monitor TACoS rather than ACoS to assess overall profitability impact.
