The Prompt
Copy and paste into your AI tool
You are a senior Amazon SEO specialist with deep expertise in search term indexing, keyword research, and backend field optimization. BEFORE YOU EXECUTE: 1. Confirm you have the current listing title, bullet points, and any existing backend search terms to audit. Gaps can only be found by comparing against what is already visible. 2. Confirm the keyword list (research data, competitor terms, or search query reports) is provided. Do not invent keywords with no basis in the provided data. 3. Count bytes, not characters -- the backend field is byte-limited. Standard ASCII characters are 1 byte each; special characters may be 2+ bytes. Flag any non-ASCII terms. 4. Do not include terms already appearing in the title or bullets -- Amazon indexes visible content separately and repetition wastes bytes. 5. Do not include prohibited content: brand names of competitors, ASINs, temporary claims (e.g., "new"), subjective claims (e.g., "best"), or offensive terms. POLICY REMINDER: Amazon's backend search terms field has a limit of 249 bytes (not characters) for most sellers. Some accounts may have access to a 500-byte limit -- check your Seller Central listing editor to confirm which applies to your account. Exceeding the byte limit by even one byte causes Amazon to stop indexing the entire field. Verify your current limit before publishing. --- TASK: Audit the existing backend search terms (if provided) and produce an optimized, byte-counted backend string using the keyword data below. OUTPUT FORMAT: **SECTION 1 -- EXISTING LISTING AUDIT** Terms already indexed via title: [extract from title] Terms already indexed via bullets: [extract from bullets] Existing backend terms (if provided): [as given] Redundant backend terms (already in title/bullets): [list] Prohibited terms found: [list or "none"] Wasted bytes from redundancy: [count] **SECTION 2 -- KEYWORD GAP ANALYSIS** | Keyword | Source | Est. Search Volume | In Title? | In Bullets? | Include in Backend? | Reason if Excluded | |---|---|---|---|---|---|---| **SECTION 3 -- OPTIMIZED BACKEND STRING** [Produce a single space-separated string of keywords, lowercase, no punctuation, no commas] Byte count: [X] / 249 bytes Remaining bytes: [X] Terms included: [count] Terms excluded (did not fit after priority ranking): [list] **SECTION 4 -- PRIORITIZATION RATIONALE** Explain in 3-5 bullet points how you ranked keywords for inclusion (e.g., search volume, relevance tier, length efficiency). **SECTION 5 -- ONGOING MAINTENANCE CHECKLIST** - [ ] Re-audit backend terms after each listing copy update (title or bullet changes free up or block terms) - [ ] Pull Search Query Performance from Brand Analytics monthly to find new gap terms - [ ] Test 3-4 new keywords per quarter by rotating lowest-performing backend terms - [ ] Re-verify byte limit if you change your Seller Central account type PASTE YOUR DATA BELOW. Include: current listing title (full text), current bullet points (all 5), current backend search terms if any (paste as-is), keyword research list with any available search volume data, product category.

Tips
01
Use a free byte counter tool (search "byte counter online") to verify your final string before pasting it into Seller Central -- copy-paste errors from word processors can silently add invisible characters.
02
Treat your backend terms as a rotating test field: swap out two or three low-priority terms each quarter and monitor organic rank changes using a rank tracker.
03
Foreign language equivalents of your primary terms (Spanish, French) are valid backend inclusions for the US marketplace and can capture bilingual search traffic without wasting visible listing space.
Frequently Asked Questions
What does the Backend Keywords Optimizer prompt do?
This prompt maximizes every byte of your Amazon backend search terms field by identifying keyword gaps not covered by your visible listing, eliminating wasted space, and producing a byte-counted, publish-ready string. Most sellers leave 30-50% of their indexing potential unused -- this prompt closes that gap systematically.
What data do I need to use this prompt?
An example of the exact input format is provided on this page under "Example Input." Generally you'll prepare your data in the structure shown, paste it after the prompt body, and the AI will return the analysis described above. If you're missing any inputs, the prompt will ask you what it needs.
How long does this take to set up?
Setup time for this prompt is < 30 mins. That includes pulling your data, formatting it to match the example, and running the prompt. Once your data pipeline is set up the first time, subsequent runs take only a few minutes.
Which AI tool should I use this with?
This prompt is designed to work with any major large language model — ChatGPT (GPT-4 or newer), Claude (Sonnet 4 or newer), or Gemini. For structured analysis, math, and tabular outputs, Claude and GPT-4 class models produce the most reliable results.
Does this prompt work for Shopify or other platforms?
This prompt is built for Amazon sellers and references Amazon-specific data points such as referral fees, FBA fulfillment fees, and ASIN-level metrics. The underlying methodology can be adapted to other platforms by substituting equivalent inputs, but the prompt as written is Amazon-first.
What skill level is required to use this prompt?
This prompt is rated intermediate. Some familiarity with your platform's data exports and basic AI prompting is helpful for getting the most out of it. Most ecommerce operators can use it productively within a single session.
Is this prompt free to use?
Yes. Every prompt in the SMB Advantage Prompt Library is free for any small business operator to use. The only cost is whatever you pay for your AI tool subscription (ChatGPT Plus, Claude Pro, etc.).
