Overview

Amazon sellers running Sponsored Products or Sponsored Brands must anchor their bids to high‑intent, data‑driven keywords. Conducting thorough keyword research before launching a campaign—and updating the list on a regular cadence—improves ad relevance, reduces ACoS, and can lift organic rankings. Mastering this workflow is critical for sellers who want to grow profitably on the platform.

Key Points

• Search volume drives exposure — Targeting a term that registers 2,000 monthly Amazon searches, such as “organic green tea bags,” yields many more impressions than a niche phrase with only 50 searches.
• Intent signals boost conversion — Keywords that include buying cues like “buy,” “best,” or “set” typically convert about 30 % better than generic descriptors such as “tea.”
• Match‑type choice controls cost — Broad match can generate roughly 1.5 × the impressions of exact match, but exact match often delivers a 20 % lower ACoS for the same keyword.
• Negative keywords safeguard budget — Adding terms such as “free” or “sample” to the negative list stops ads from appearing on low‑value searches, preserving spend for high‑intent traffic.
• Search‑term reports uncover hidden opportunities — Reviewing the “search term” column after a week of spend can reveal profitable long‑tail phrases that were absent from the original list, for example “detox green tea for weight loss.”

How Keyword Research Works

1. Collect seed keywords — Extract product titles, bullet points, and competitor listings into a spreadsheet; for a stainless‑steel water bottle, seed terms might include “insulated water bottle,” “travel mug,” and “hydro flask alternative.”
2. Confirm search volume — Use Amazon Brand Analytics or a reputable third‑party tool to verify each seed’s monthly search count; a phrase like “insulated water bottle 32 oz” showing 3,800 searches qualifies for primary targeting.
3. Evaluate relevance and buyer intent — Rank every keyword by how tightly it aligns with the product’s core features; “leak‑proof water bottle” scores high on relevance, while “water bottle accessories” ranks lower and may be placed in a secondary ad group.
