Quick Definitions – What Is an Advertising Consultant vs an In-House PPC Manager?

Advertising Consultant (freelance / consultant / boutique agency)

An advertising consultant is an external Amazon PPC expert or agency who handles audits, strategy, scaling, campaign rebuilds, product launches, ad structure, and team training. They typically work project-based or monthly retainer-based. Consultants are ideal for fast audits, deep expertise, advanced buildouts, or temporary help during scaling phases.

In-House PPC Manager

An internal PPC manager is your full-time employee focused on day-to-day campaign operations, reporting, optimization cycles, experiments, inventory alignment, cross-department coordination, and long-term growth execution. They offer control and continuity but may lack advanced tool access or broad experience across accounts.

Snippet: 45-Word Comparison

An advertising consultant provides fast expertise, advanced tools, and external strategic guidance. An in-house PPC manager provides continuity, control, and day-to-day ownership. Consultants scale rapidly; in-house teams retain knowledge internally. The right choice depends on budget, speed, and long-term goals.

Pros & Cons – Advertising Consultant vs In-House PPC Manager

Factor	Advertising Consultant	In-House PPC Manager
Cost	Predictable retainer or hourly; cheaper short-term	Expensive long-term (salary + benefits + tools)

Interpretation by Business Size

• Enterprise ($300k+/mo) → In-house team + consultant for audits & advanced scaling.

Break-Even Calculator Logic

When does an agency become cheaper than in-house?

Formula:
(Agency Monthly Cost × 12) < (PPC Manager Salary + Tools + Training)

Example:

• Agency: $4,000/month → $48,000/year
• In-house: $85,000 salary + $12,000 tools → $97,000/year
  → Agency is cheaper until you cross $60k–$100k/mo in ad spend.
