How to Discover Backend Search Terms Your Competitors Are Using (Without Guesswork)

The best-performing Amazon listings aren’t winning just because they have pretty pictures or clever bullets. They’re winning because they’re showing up before you do.

And often, that edge?
It’s hiding in backend search terms. These are the invisible keywords powering discoverability behind the scenes. But here’s the good news: You don’t need to be psychic or rely on random keyword generators. You just need your competitor’s ASIN and the right tool to decode what Amazon’s algorithm is actually reading.

Welcome to your competitive advantage: SellerApp’s Reverse ASIN Tool.

First, What Are Backend Search Terms and Why Should You Care?

Backend keywords are invisible to shoppers but visible to Amazon’s A10 algorithm. They don’t show up in the title or bullet points. However, they heavily influence how and where a product ranks.

These terms often include:

• Common misspellings
• Synonyms and variations
• Occasion-based or trend-based keywords
• Foreign-language terms (especially in multi-lingual markets)
• Long-tail phrases with low competition

The kicker? Most sellers don’t optimize for them well or at all. Which means if you do, you’re automatically ahead.

Step-by-Step: Uncovering Competitor Backend Keywords Using SellerApp’s Reverse ASIN

Here’s how to reverse-engineer what your competitors are using behind the curtain:

Step 1: Log in to SellerApp

• Visit dashboard.sellerapp.com/login
• Sign in using your SellerApp credentials

Step 2: Access the Reverse ASIN Tool

• Go to Tools section in the left sidebar

Select Reverse ASIN under Tools

Step 3: Enter the Competitor’s ASIN

• Copy the ASIN of the product you want to analyze (from Amazon product URL)
• Paste it into the search bar and hit Analyze

SellerApp will now generate a keyword list associated with that ASIN.

Step 4: Filter for Organic-Only Keywords

To isolate potential backend search terms:

1. Remove brand-specific or obvious front-end keywords that are already in the title, bullet points, or description.

What’s left? Likely backend keywords. The  ones the seller is using in the backend to boost discoverability!

Step 5: Identify Patterns and Gaps

Now that you have a filtered list of potential backend terms, look for:

• Misspellings: “coffe mug” instead of “coffee mug”
• Synonyms: “beverage holder” for a mug
• Foreign language keywords (e.g., “taza” in Spanish)
• Seasonal or occasion-based phrases: “Father’s Day gift”, “Christmas decor”

Now, SellerApp’s Reverse ASIN Tool is designed to help Amazon sellers improve their product listings and advertising performance by analyzing competitors’ listings. 

Here’s what you can pull of with the Reverse ASIN tool:

1. Optimize Your Listing

       What it means:

• You can extract top-performing keywords from your competitors’ listings using their ASINs (Amazon Standard Identification Numbers).

• These keywords are what help their products rank higher in search results.

How it helps:

• Add those high-ranking keywords to your own product titles, bullet points, descriptions, and backend search terms.

• This increases your visibility and helps attract more potential buyers.

Goal: Make your listings more discoverable and competitive.

 2. Identify Keyword Gaps

What it means:

• You can compare your ASIN with up to 4 competitors to see which keywords they are ranking for that you are not.

How it helps:

• These are keyword opportunities—terms that your audience is using to find similar products, but you’re missing out on.

• Closing those gaps can significantly improve your organic ranking and conversion rates.

Goal: Expand your keyword strategy to cover missed opportunities.

3. Generate More Sales

What it means:

• The tool highlights high-converting keywords—those that are not just driving traffic but also resulting in sales for your competitors.

How it helps:

• You can use these keywords in your PPC campaigns (Amazon Ads) to target the right buyers.

• This improves your ad ROI and drives more qualified traffic to your listings.

 Goal: Boost ad effectiveness and increase sales by targeting proven keywords.
