Playbook
Comment CTAs that really work, word for word
Five rules, each with a real line you can copy. Then one template.
The short answer
A strong comment CTA uses one capital word, ties it to what people get, says it's free, names the thing, and appears on the last slide and in the first line of the caption. The template: Comment WORD and I'll send you the thing. It's free.

The five rules
- 01
One capital word. "Comment PLAYBOOK and I'll send you the doc." (Jenna Kutcher)
- 02
Tie the word to the thing. "Comment '100LEADS' to get a free scaling roadmap." (Alex Hormozi)
- 03
Say free. "Reply 'HACK' if you want a free tutorial." (@instacoachmike)
- 04
Name what they get. "Comment TRAFFIC to get my free webinar." (Jenna Kutcher)
- 05
Put it in two places: the last slide and the first line of your caption. "Comment RICH and I'll DM you the link." (Chalene Johnson, whose post got 7 times more comments than likes)

Questions
On the last slide or at the end of the reel, and in the first line of the caption.
In your copy, yes, so it stands out. Postkey matches the word in any case.
One line. Say the word and what they get.
