Hero ASIN
Last updated: February 4, 2025
What is a Hero ASIN?
A Hero ASIN (also called a hero SKU or flagship product) refers to the best-selling, highest-revenue product or products in an Amazon seller's portfolio. These top performers generate the majority of revenue and are the core of any successful Amazon strategy.
The term originates in the Amazon seller community and describes products with a high conversion rate, an excellent Bestseller Rank and strong profitability, which are preferentially supported with ad budget.

The Pareto principle in your Amazon portfolio
The Pareto principle (the 80/20 rule) is the foundation of the Hero ASIN strategy: typically, 20% of products generate about 80% of revenue. Those 20% are your Hero ASINs.
The 80/20 rule on Amazon:
of your ASINs
= Hero ASINs
of your revenue
= focus for ads & optimization
Instead of advertising your entire assortment evenly, you concentrate resources on the products with the highest ROI. That means: more ad budget, more intensive listing optimization and better inventory management for Hero ASINs.
Identifying Hero ASINs
To identify your Hero ASINs, analyze your portfolio against these criteria:
Revenue share
Which ASINs generate the highest absolute revenue? Sort your portfolio by revenue and identify the top 20%.
Profitability / margin
High revenue alone isn't enough. Analyze the gross margin after deducting Amazon fees, advertising costs, and product costs. High-margin ASINs deserve more ad budget.
Conversion rate
Hero ASINs have above-average conversion rates (typically 10-20%+). They turn traffic into sales efficiently and benefit especially from additional advertising.
Bestseller Rank (BSR)
A low, stable BSR in the main category indicates consistently high sales figures. A fluctuating BSR can point to seasonal products or inventory issues.
Ratings & reviews
Strong Hero ASINs have many positive reviews (1,000+) with an average of at least 4 stars. This social proof reinforces advertising success.
Analysis tip:
Use the Business Reports in Seller Central (Reports → Business Reports → Detail Page Sales and Traffic) for revenue, sessions, and conversion rate per ASIN. Combine this data with your margins from your cost calculation.
ASIN portfolio strategy
Successful Amazon sellers segment their portfolio into different ASIN types with distinct strategies:
| ASIN type | Description | Strategy |
|---|---|---|
| Hero ASIN | Top performer, high margin, strong conversion | Aggressive bidding, maximum visibility, premium content |
| Launch ASIN | New products in the ramp-up phase | Higher ACoS acceptable, focus on ranking & reviews |
| Steady ASIN | Stable performers, mid-range margin | Moderate advertising, efficiency focus, hold the ACoS target |
| Long-tail ASIN | Niche products, low sales | Minimal advertising, let them run organically |
| Liquidation ASIN | Phase-out products, excess inventory | Discount promotions, strict ACoS limits, sell-off |
Important: identify a backup hero
Identify not only your Hero ASIN but also the next-best ASINs. If your hero product runs into supply issues, goes out of stock, or gets penalized, you can quickly pivot to the backup hero.
PPC strategy for Hero ASINs
Hero ASINs deserve a dedicated PPC strategy with a larger budget and more aggressive targeting:
Separate campaigns
Create dedicated campaigns for Hero ASINs instead of mixing them with other products. That way you keep full control over budget and bids.
- • Dedicated Sponsored Products campaign (Exact, Phrase, Broad)
- • Dedicated Sponsored Brands campaign with the Hero ASIN in focus
- • ASIN targeting on competitor products
Aggressive bidding
Hero ASINs convert well – invest in top placements:
- • Top of Search placement modifier: +50-100%
- • Accept higher bids for converting keywords
- • Use dynamic bidding “Up and Down”
ASIN targeting
Use product targeting to appear on competitors' detail pages:
- • Target competitors with weaker reviews
- • Target complementary products (cross-selling)
- • Target your own weaker ASINs (upselling to the Hero ASIN)
Budget prioritization
Allocate 50-70% of your total budget to Hero ASINs. Make sure hero campaigns are never constrained by budget limits – a “Limited by Budget” status on Hero ASINs is lost revenue.
ACoS targets by ASIN type:
Hero ASIN: 15-25% ACoS
Keep it low, since it's profitable
Launch ASIN: 30-50% ACoS
Higher is acceptable for ranking
Steady ASIN: 20-30% ACoS
Break-even or slight profit
Liquidation: < break-even
Minimize the loss
Optimizing & scaling Hero ASINs
Continuous optimization is the key to keeping Hero ASINs at the top level:
1. Prioritize listing optimization
Hero ASINs deserve A+ premium content, professional images, videos, and perfect bullet points. Use A/B tests (Manage Your Experiments) for continuous improvement.
2. Inventory planning
Hero ASINs should always have 60+ days of inventory coverage. Below 30 days: throttle ad spend to avoid stockouts. An out-of-stock on a Hero ASIN is catastrophic for ranking and revenue.
3. Review management
Keep your review velocity high: use “Request a Review,” Amazon Vine (for variations), and excellent customer service. Respond to negative reviews quickly.
4. Expand variations
Successful Hero ASINs can be expanded through variations (colors, sizes, bundles). The existing reviews and rankings help the new variations get off the ground.
5. Internationalization
A Hero ASIN in one market can also succeed in other EU markets (UK, FR, IT, ES) or the US. Leverage the proven product for expansion.
Avoiding common mistakes
Treating all ASINs the same
Advertising your entire portfolio with the same ACoS target and budget wastes resources. Prioritize Hero ASINs deliberately.
Neglecting the Hero ASIN
“It runs by itself” is a dangerous assumption. Competitors copy successful products. Continuous optimization and defense are mandatory.
Betting on a single Hero ASIN
A single top performer is a concentration risk. Develop 2-3 Hero ASINs and build a pipeline for new candidates.
Stockouts on Hero ASINs
An out-of-stock on your bestseller destroys rankings that took months to build. Plan safety stock and monitor your sell-through rate.
Ignoring margin
High revenue at a low margin makes no sense. A Hero ASIN has to be profitable – otherwise it's just a revenue driver with no real value.
Frequently asked questions (FAQ)
How many Hero ASINs should I have?
It depends on your portfolio size. With 50 products, you should identify 5-10 Hero ASINs (10-20%). With 10 products, maybe 1-2. What matters is concentrating resources on the top performers.
Can a Launch ASIN become a Hero ASIN?
Yes, that's the goal. Successful product launches go through phases: Launch → Steady → Hero. Not every product makes it, but the best Launch ASINs become the new Hero ASINs.
What should I do if my Hero ASIN loses performance?
Analyze the cause: new competitors? Price pressure? Listing issues? Negative reviews? Seasonality? Respond with listing updates, price adjustments, or increased advertising. In parallel, prepare the backup hero.
Should I also advertise weak ASINs?
To a small extent, yes – to gather data and identify potential new Hero ASINs. But the bulk of the budget belongs to the proven top performers. Weak ASINs with poor conversion just waste money.
How often should I review my Hero ASIN portfolio?
Run a detailed analysis monthly, with a quick weekly check of the key metrics (revenue, BSR, conversion rate, ACoS). For seasonal products, the composition can vary by season.
