Sponsored Products vs. Sponsored Brands — how do you split budget as a new seller?

PPC & Marketing

Sellers often make the mistake of splitting their PPC budget 50/50 between Sponsored Products (SP) and Sponsored Brands (SB) right out of the gate.

For a new seller or new ASIN, a 80/20 or 80/10/10 rule is far more effective. Sponsored Products is a high-intent demand harvester, whereas Sponsored Brands requires brand registry, existing catalog depth, and established social proof to convert efficiently.

Here is how to structure your ad budget step-by-step from launch to scale.

1. Budget Split Framework by Account Stage

[ New Seller / Launch ]  ➔  80% SP  | 15% SB  | 5% SD
[ Scaling Phase ]        ➔  65% SP  | 25% SB  | 10% SD
[ Brand Defense / Scale ] ➔  50% SP  | 35% SB  | 15% SD
Account Stage Sponsored Products (SP) Sponsored Brands (SB) Sponsored Display (SD) Primary Objective
Launch Phase (0–3 Months) 80% 15% 5% Driving search indexation, collecting keyword data, and securing initial reviews.
Growth Phase (3–6 Months) 65% 25% 10% Defending branded search, expanding top-of-page real estate, and retargeting.
Mature / Brand Phase 50% 35% 15% Market share defense, New-to-Brand (NTB) acquisition, and cross-selling catalog SKUs.

2. Why New Sellers Should Heavy-Weight Sponsored Products

:bullseye: Conversion Rates Are Significantly Higher

  • SP Performance: Sponsored Products average a 10%–15% conversion rate (CVR) because shoppers clicking SP ads are usually ready to buy a specific solution.

  • SB Performance: SB ads sit higher in the funnel (top of search results or video slots). Conversion rates typically average 4%–8% because shoppers are still browsing. Spending heavily on SB with zero reviews will burn cash fast.

Clicks and sales generated through Sponsored Products directly feed Amazon’s A10 organic search ranking algorithm for those specific keywords. SB sales help, but SP gives you tighter, direct keyword-to-ASIN ranking correlation.

If you only have 1 to 3 active SKUs, standard SB formats (like Product Collections) require product variety or catalog depth. SP allows you to hyper-focus every ad dollar on your main hero SKU.

3. How to High-Jack Efficient SB Sales on a Budget

If you are Brand Registered, do not skip Sponsored Brands entirely—just use the right formats:

  1. Sponsored Brands Video (SBV): Allocate 70%+ of your SB budget to video ads. In search results, auto-playing video ads regularly pull 1.5x–2x higher CTR than static banner ads at a lower effective CPC.

  2. Branded Search Defense: Set up a low-budget SB campaign targeting your exact brand name and variants. This locks up the entire top of the Search Results Page (SERP) so competitors cannot conquer your traffic .

  3. Avoid Generic SB Banners Early On: Do not run broad top-of-funnel category banner ads until your product listing has a strong review count (30+ reviews) and established social proof.

4. Key Rules for Optimization

  • Start Auto-Campaigns in SP First: Use SP Auto Campaigns to harvest high-converting search terms, then move those exact keywords into manual SP and SB campaigns.

  • Watch Your TACoS (Total Advertising Cost of Sale): Keep overall ad spend within 10%–15% of total gross revenue during normal operations (allowing 20%–25% briefly during launch).

  • Track New-to-Brand (NTB) Metrics on SB: When judging Sponsored Brands, look beyond standard ACoS. Evaluate NTB sales % to see how effectively SB is bringing first-time buyers into your catalog.
