Synonyms with the AMALYZE Extension — every indexed keyword, on every ASIN.

Episodes 03 and 04 covered sources you can read off the SERP itself: the category and competitor titles. They're free, but they only surface keywords that already made it into someone's visible copy. The AMALYZE Extension goes one layer deeper — to the keywords Amazon's index has actually associated with a listing, regardless of whether they appear in the title or bullets.

What the Extension does

The AMALYZE Extension is a browser plug-in that injects an overlay panel onto every Amazon SERP, detail page and search bar. On a detail page, the panel shows: the keywords the ASIN is indexed for, the rank position per keyword, the monthly search volume, the relevance score Amazon's algorithm has assigned, and any backend-terms signal the data exposes. On the SERP, the same panel scores each visible competitor's keyword overlap with the query you ran.

Why this beats SERP-reading alone

• Index vs. visibility. A keyword in backend search terms is indexed but invisible on the page — SERP-reading misses it entirely. The Extension reads from data that reflects the actual index.
• Rank is data, not narrative. "This competitor probably ranks well for X" becomes "this competitor is rank 7 on X with 12,400 monthly searches." Decisions improve.
• Search volume on the same screen. Pairs every candidate synonym with its volume immediately — half of Episode 14's evaluation work is already done.
• Backend-terms inference. When a competitor ranks for a keyword that does not appear on their visible copy, the Extension flags it as a likely backend-terms placement — pure intelligence about how the leaders use the invisible field.

The workflow on a single competitor

1. Open the top-3 organic ASIN for your category's main query.
2. Open the Extension panel. Sort the keyword list by rank position ascending — the top 30 ranks are the keywords driving most of this ASIN's organic traffic.
3. Copy the top 30 keywords into your working sheet. Mark which are in the visible title (those are competitor's high-conviction keywords) and which are not (those are competitor's backend bets).
4. Repeat for the next two competitors. Look for keyword overlap across all three — overlap is signal, single-competitor uniqueness is noise.

The workflow on a SERP

1. Run your main query. Open the Extension SERP overlay.
2. Each visible tile now shows its rank for the current query plus its top adjacent keywords.
3. Filter by "keywords this ASIN ranks for that the current query does not contain" — that's the lateral synonym list. These are queries Amazon thinks are conceptually related but use different vocabulary.

What to harvest, what to skip

• Harvest. Any keyword that three or more top-30 competitors share. Any keyword with monthly volume above your category's median where a competitor ranks in the top 20.
• Skip. Brand-only queries belonging to competitors. Branded-misspelling queries. Queries with rank above 100 — those don't drive meaningful traffic and indicate the keyword is poorly matched.

The privacy and ethics line

The Extension reads public data — the same data Amazon serves to any shopper, structured and surfaced. It does not access Seller Central data, not in your account and certainly not in any competitor's account. The output is the same intelligence a careful manual analyst would compile in a day, compressed into a panel you read in 30 seconds.

How this source feeds the rest of the module

Extension data is the largest single contributor to a category's working synonym list — typically 60–120 candidates per ASIN analysed. Episode 14's evaluation pass cuts it to the 20–30 keywords that actually deserve a slot. Episodes 15 and 17 cover the workflow that merges Extension output with the AMALYZER product (the next-layer keyword research tool).
