Overview

This case study covers an Amazon ranking campaign executed by AZ Rank for a product in the highly competitive Health & Household / Trace Mineral Supplements niche. The seller was already a strong performer — moving more than 10,000 units per month — but their top three keywords were buried on page 3 or worse, leaving significant organic revenue on the table.

Despite being the category best seller, the product was not ranking for its most important keywords — creating the central challenge for this campaign.

The Challenge

The top 3 keywords driving the most search volume and sales in this niche were poorly indexed for this product. Starting ranks were:

Keyword	Starting Rank (Day 0)	Keyword Sales	Search Volume
KW1	26	545	6,996
KW2	36	1,557	30,187
KW3	40	2,423	41,981

With KW3 alone reaching nearly 42,000 monthly searches, poor placement at position 40 meant the product was practically invisible for that term.

Campaign Goals

Strategy

AZ Rank followed a structured 3-step approach that could be partially guided by the seller or handled entirely by the AZ Rank team.

Date	Units / Day
03/04	16
03/05	19
03/06	22
03/07	24
03/08	25
03/09	21
03/10	19

Execution

During the 8-day campaign, the team tracked rank evolution daily and made on-spot adjustments — increasing or decreasing pace, shifting keyword focus, or modifying the plan as needed. By day 8, all three keywords had dramatically improved:

Keyword	Day 0	Day 8	Improvement
KW1	26	4	+22 positions
KW2	36	7	+29 positions
KW3	40	9	+31 positions

An additional benefit of the campaign format: buyers completed a market research survey alongside their purchase, providing the seller with structured, actionable feedback on the listing, product photos, ingredients, and competitor perceptions — along with verified Order IDs.

Rank Evolution

18 Days After the Campaign Ended

One of the key goals was rank stickiness — ensuring the gains held after the campaign concluded. Helium 10 tracking data for all three keywords confirmed that rankings stabilised near the top 10 and, in some cases, continued to improve.

---

Sales Insights

The Helium 10 sales tracker confirmed a consistent upward trend throughout the campaign period. Daily sales climbed from around 20–22 units at the start of February to a peak of over 50 units in mid-March, with the 7-day moving average confirming the trend line.

BSR (Best Seller Rank) data shows a price drop during the campaign window that supported conversion, while sales velocity increased substantially.

---

Number of Keywords Ranked

Beyond the targeted 3 keywords, the overall keyword footprint of the listing expanded significantly over 28 days — a downstream effect of improved organic visibility and sales velocity.

---

Search Volume Evolution

More keywords ranking higher translated directly into a larger addressable search audience. Total indexed search volume across ranked keywords grew substantially over the 28-day window.

---

Sales Evolution

Revenue impact was clear. Over 28 days, units sold increased and monthly revenue grew substantially — reinforcing the relationship between organic rank improvements and bottom-line sales performance.
