Amazon Listing Optimization Checklist: 12 Things to Fix Before You Run Ads

Running ads to an unoptimized listing is the fastest way to waste your ad budget. Traffic hits the page, conversion rate is low, ACoS climbs, and you assume the ads aren't working. Usually the ads are fine — the listing is the problem.

This checklist covers the 12 elements that matter most for Amazon listing performance. Before you increase ad spend, go through every item here. Each one either directly impacts search ranking, conversion rate, or both.

1. Title — Keywords First, Readable Second

Your title is the single most important field for Amazon's A9 search algorithm. It needs to lead with your primary keyword, include 2–3 secondary keywords naturally, and still read like something a real buyer would click.

What to check:

• Primary keyword appears in the first 5 words

• Title is between 150–200 characters (category-dependent — check your category style guide)

• No keyword stuffing — if it reads like a robot wrote it, rewrite it

• Brand name is present (important for branded search)

• No special characters, promotional phrases, or subjective claims ("best," "#1")

A weak title is the most common listing problem we see in new accounts. A single title rewrite has moved listings from page 5 to page 1 for target keywords.

2. Bullet Points — Benefits Over Features

Five bullet points, each starting with a bolded key benefit. Buyers scan bullets — they don't read them. Each one should answer a specific objection or reinforce a purchase reason in 1–2 sentences.

What to check:

• Lead each bullet with a bold benefit phrase in all caps or title case

• Address the top 5 buyer objections or use cases

• Include secondary keywords naturally — Amazon indexes bullet point content

• Each bullet is 150–300 characters

• No HTML tags, no promotional language, no price references

3. Product Description — Still Relevant for Unregistered Brands

If you have Brand Registry, your A+ Content replaces the product description in the customer-facing display. But the description field still gets indexed by Amazon's algorithm, so it's worth filling with keyword-rich copy even if buyers don't see it directly.

If you don't have Brand Registry yet, your description is the primary long-form content on the page. Make it count — lead with the core value proposition, address use cases, and close with a call to action.

4. Backend Search Terms — Fill Every Character

250 bytes of backend keyword space that most brands either leave empty or fill with duplicates. Amazon indexes these, buyers never see them.

Rules:

• No duplicates — words already in your title don't need repeating

• No commas — Amazon ignores them, they just waste space

• Use synonyms, misspellings, and complementary search terms your title couldn't fit

• Include Spanish keywords if relevant to your audience

• Stay under 250 bytes (not characters — some characters are multi-byte)

5. Main Image — White Background, Full Frame, No Exceptions

Amazon requires a pure white background (#FFFFFF) for main images, with the product filling at least 85% of the frame. This is table stakes. What separates good main images from great ones is how clearly they communicate the product at thumbnail size — because that's how most buyers will see it first.

What to check:

• Pure white background — no shadows, gradients, or props

• Product fills 85%+ of frame

• Image is at least 1,000 x 1,000 pixels (required for zoom)

• No text, logos, badges, or watermarks on the main image

• Product is clearly identifiable at 100px thumbnail size

The main image is the single biggest lever for click-through rate. A better main image means more clicks from the same ad spend and organic impressions.

6. Secondary Images — Answer Every Buyer Question

You have 6–8 image slots. Use all of them. Each image should address a specific question a buyer would have before purchasing: What does it look like in use? What's included? How big is it? What are the key features? Is the quality evident?

Standard image sequence that converts:

• Image 2: Lifestyle — product in real use

• Image 3: Key features callout — annotated product view

• Image 4: Benefits — problem/solution framing

• Image 5: Size/scale reference

• Image 6: What's in the box

• Image 7: Social proof / awards / certifications

• Image 8: Brand story or comparison chart

7. A+ Content — Non-Negotiable for Brand-Registered Sellers

A+ Content (formerly Enhanced Brand Content) replaces your product description and adds rich media modules: comparison charts, lifestyle imagery, feature highlights, and brand story sections. It's free to create and consistently improves conversion rate by 3–10% for most categories.

If you have Brand Registry and you don't have A+ Content on your top 20 ASINs, fix that before doing almost anything else.

What good A+ Content includes:

• Brand story module

• Product comparison chart (especially useful for variation families)

• Feature highlights with supporting imagery

• Use case or lifestyle modules

• Cross-sell module linking to related products

8. Pricing — Competitive Without Race-to-Bottom

Price affects Buy Box eligibility, conversion rate, and ad efficiency all at once. It doesn't need to be the lowest — but it needs to be defensible relative to competitors with similar reviews and images.

What to check:

• Price is within 10–15% of the top 3 competitors on your target keyword

• You're not leaving profit on the table by underpricing relative to quality signals (reviews, brand strength)

• You have a strategy for discounting (coupons, limited promotions) rather than permanent price cuts

• Subscribe & Save is enabled where applicable (increases LTV and conversion)

9. Reviews — Quantity and Recency Both Matter

You can't directly control reviews, but you can influence them. Reviews affect conversion rate more than almost any other factor — 50+ reviews at 4.0+ stars is the threshold where most listings start converting at a meaningful rate. Under 15 reviews, you're at a significant disadvantage in competitive categories.

What to check:

• Are you enrolled in Amazon Vine for new ASINs? (First 30 reviews free for Brand-Registered sellers)

• Are you using the "Request a Review" button in Seller Central for every order?

• Are negative reviews getting a response that addresses the issue publicly?

• Are recent reviews trending positive, or is there a quality issue that needs addressing?

10. Inventory Status — Never Out of Stock on Your Hero SKUs

Stockouts kill organic rank. When you go out of stock, Amazon drops your keyword rankings — and rebuilding them takes time and ad spend. For your top 5 revenue-generating ASINs, stockouts are never acceptable.

What to check:

• Current IPI (Inventory Performance Index) score — should be 400+

• Reorder points set for top SKUs based on lead time + safety stock

• FBA inbound shipments in transit before you hit zero

• FBM backup listings active for top SKUs as stockout insurance

11. Variations — Structured Correctly, Not Just Grouped

Variation architecture affects discoverability, review consolidation, and conversion. Bad variation structure (wrong variation theme, incorrectly grouped products) can actually hurt performance by confusing the algorithm or fragmenting reviews across ASINs that should be consolidated.

What to check:

• All color/size/style variants are grouped under one parent ASIN

• Variation theme matches the category standard (color, size, style — not "option")

• Child ASINs are not suppressed

• Reviews are accumulating on the parent, not fragmented across unrelated parents

12. Suppressed Listings and Policy Flags

You can't rank or convert on a suppressed listing. Amazon suppresses listings for missing required attributes, policy violations, image issues, pricing anomalies, and dozens of other reasons — and the notification isn't always obvious.

Where to check:

• Seller Central → Inventory → Fix Stranded Inventory

• Seller Central → Performance → Account Health → Listing Issues

• Seller Central → Inventory → Manage All Inventory → filter by "Suppressed"

Stranded inventory (FBA units with no active listing) is a common and expensive problem. Units are sitting in a fulfillment center costing you storage fees while generating zero sales.

How to Prioritize If You Can't Fix Everything at Once

If you're working through this checklist on a large catalog, prioritize in this order:

1. Suppressed listings — no active listing means zero sales, fix immediately

2. Main image — highest impact on CTR, affects every impression

3. Title — highest impact on organic ranking and ad relevance

4. A+ Content — free conversion rate improvement for all brand-registered ASINs

5. Reviews — long lead time, start the process now

6. Everything else — work down the list for remaining SKUs
