5 free things people will actually comment for
The keyword only works if the thing you're giving away is worth typing a word for. These five have proof behind them.
The short answer
The freebies that get comments are small and specific: a bonus with a product, a seat at a free class, a recipe card or one-page PDF, a list of what you used, or a short cheat sheet. Each one below comes from a real creator's funnel.

The five
Numbers are from the published case study and are self-reported. Results vary, and the tool used in the study was not Postkey.
- 01
A bonus with your book or product. Amy Porterfield did this and got 924 confirmed purchases from one reel.
- 02
A seat at a free class. On Jenna Kutcher's webinar funnel, 85% of commenters registered.
- 03
A recipe card or one-page PDF. Jasmine Lemire made hers in Canva, put it on Google Drive and got 7,000 comments in a day.
- 04
A list of what you used. Katrina Niesen's red bow loaf reel reached about 6 million views, and commenting "red" got you her tools and powders.
- 05
A short doc or cheat sheet. Jenna's line: "Comment PLAYBOOK and I'll send you the doc. It's free, and it lands in your DMs in seconds."
How to choose
Pick the one you can make this afternoon. Jasmine's card took a design tool and a shared link. It doesn't need to be big. It needs to be something people want right now.

Questions
A one-page PDF or a list of the products you used. You can make either in an hour.
Anywhere with a link, such as a shared drive or your own site.
You can, and Postkey can ask inside the DM. Sending the freebie first still works if you want the most comments.
