Client Background

The client was an established Amazon seller generating consistent traffic but struggling with profitability.

Their business relied heavily on Amazon PPC advertising, but the campaigns were poorly structured.

Problems included:

  • extremely high ACOS
  • unoptimized keyword targeting
  • no negative keyword strategy
  • excessive reliance on auto campaigns

Despite spending over $38,000 per month on Amazon advertising, the seller’s TACoS continued to rise.

The brand approached EcomRanker to build a scalable Amazon PPC strategy that would reduce ad spend while increasing organic growth.

Major Problems Identified

After performing a deep Amazon PPC audit, we discovered several issues.

Problem 1: Campaign Structure Chaos

The account had 47 campaigns with no clear structure.

Common problems included:

  • duplicate keyword targeting
  • mixed match types
  • poor budget allocation

As a result, ad spend was inefficient.

Problem 2: No Negative Keyword Strategy

The seller was spending heavily on irrelevant search terms.

Examples included:

  • competitor brand names
  • unrelated product categories
  • low purchase intent keywords

Nearly 29% of ad spend was wasted.

Problem 3: Low Conversion Rate

Even when ads generated clicks, customers were not converting.

Key reasons included:

  • weak product images
  • poor bullet points
  • lack of trust signals

Problem 4: No TACoS Strategy

Most agencies optimize for ACOS only.

However, focusing solely on ACOS can harm organic ranking.

Our strategy focuses on TACoS optimization, which measures ad spend relative to total revenue.

EcomRanker PPC Strategy

We implemented a TACoS-driven growth framework.

Step 1: Campaign Architecture Rebuild

We rebuilt the entire PPC structure.

Campaign types included:

Discovery campaigns

Auto campaigns used for keyword discovery.

Research campaigns

Phrase match targeting for keyword testing.

Ranking campaigns

Exact match targeting for top keywords.

Defense campaigns

Brand protection campaigns.

Step 2: Search Term Mining

We analyzed 120,000+ search queries from historical campaign data.

This helped identify:

  • profitable keywords
  • irrelevant search terms
  • high conversion search queries

Step 3: Negative Keyword Strategy

We implemented a comprehensive negative keyword strategy.

Types included:

  • phrase negatives
  • exact negatives
  • competitor negatives

This immediately reduced wasted ad spend.

Step 4: Bid Optimization

We adjusted bids based on performance data.

High-performing keywords received increased bids.

Low converting keywords were reduced or paused.

Step 5: Listing Conversion Optimization

PPC alone cannot fix profitability issues.

We improved listing conversion by:

  • optimizing product images
  • rewriting bullet points
  • adding A+ content
  • improving product title
