Can business coaches advertise client results?

Results are the most persuasive proof available and the most exposed, so the framing matters.

Two problems with results advertising in this field. Business outcomes have many causes, and attributing revenue growth to coaching is difficult to substantiate even when the engagement genuinely helped. And claims implying typical results carry substantiation expectations, which a single client's outcome cannot support.

What works and holds up:

• Specific examples with explicit permission, framed as one client's experience rather than as a representative outcome.
• Describe what changed operationally rather than only the financial result. The owner delegated three functions, or built a management layer, or moved from reactive to planned hiring. That is credible and verifiable.
• Let clients tell their own story in their words, with permission, rather than summarizing outcomes yourself.
• Avoid aggregate claims such as average growth figures unless you can genuinely substantiate them.
• Avoid guarantees, including implied ones.

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