Can I say it?

Can I say “only 5 spots left” in a clinic ad?

Usually no. 2 rules fired across 3 sample sentences, and the checker's own text explains why.

The short answer

Usually no. The checker blocks the bare phrase in this setting. The first rule it hits is CG-OFF-004. Its reason: Urgency and scarcity claims must be true, and false urgency is deceptive.

Source the rule cites: FTC Act section 5

Checked as an ad promoting a clinical service.

A clear result is not an all-clear. The checker flags wording for review and does not know your evidence, your state or your platform's review. Read the limitations.

Appointments book up. See the schedule and pick a time that works for you.

Actual checker output: no rule fired. It still has to be true for your business.

What the rules themselves suggest:

  • CG-OFF-004 Use a real deadline and state it, or remove the urgency.
  • CG-OFF-008 Use a real deadline, state it, and do not suggest a drug will run out or that prices will jump unless that is documented and true.
