Can career coaches advertise outcomes like salary increases?

Outcome and earnings claims are the most persuasive material available in this category and the most exposed.

Two issues. Claims implying typical results carry substantiation expectations, and a single client's outcome is rarely representative. And salary or placement claims are difficult to substantiate even when true, because the coach's contribution to a hiring outcome cannot be isolated from the market, the candidate and timing.

What is safer and still persuasive:

• Describe what the engagement involves rather than what it produces. The process is what the client is buying and what you actually control.
• Use specific client examples with explicit permission, anonymized where employment situations are identifiable, and framed as one person's experience rather than as a typical result.
• Avoid aggregate figures such as average salary increases, unless you can substantiate them properly.
• Avoid guarantees entirely, including implied ones like phrasing that suggests placement.

Confirm what advertising standards apply to your claims in your jurisdiction. This is a general framing rather than guidance on any specific rule.
