How free-form ads work on Reddit
Free-form is the most Reddit-native format ever sold: rich text, images, GIFs, video and links in one promoted megathread. This guide covers the spec, the voice and the cases.

Reddit free-form ads combine text, images, videos and more in a single promoted post, with a headline to 300 characters and a body to 40,000 characters. They serve in feed and conversation for Awareness plus Traffic, and early testing found a 28 per cent clickthrough edge.
Modelled on the megathread#
Reddit describes free-form as inspired by one of its most popular post types, the megathread: the community long post where depth signals care. That shapes everything. A 2,000-word honest teardown with receipts reads like the community because it is shaped like the community; a press release with paragraph breaks is recognised in seconds, and the recognition is public. Announcement: Reddit free-form launch.
The thumbnail rule#
Free-form ads without a thumbnail show no media in feeds, so the thumbnail is distribution, not decoration. Choose one legible frame that promises the depth inside: a teardown chart, a before-and-after, a face mid-argument. Test the thumbnail as its own variable, because in feed it is the entire first impression. Spec detail: free-form specifications.
Depth that converted#
Canada Goose ran Reddit-native free-form storytelling to a reported 10.5-point awareness lift with 2.58x ROAS. Oatly deliberately invited controversy and routed readers to a fact-checking site rather than suppressing critics. SEGA used free-form education inside a launch built with targeted posts and a category takeover. The pattern across all three: a genuine point of view, receipts, and open comments. See the free-form deck for the full breakdown.
Comments are the format#
Long-form invites replies, so staff the thread like the second half of the buy: monitor, answer helpfully, acknowledge objections concretely. Read sentiment, questions and recurring language as creative intel no dashboard provides. Disabling comments on a format built for discussion surrenders its main advantage; only do it when moderation genuinely cannot be staffed. Playbook: comment management.
When free-form wins#
Product deep-dives, explainers, shopping guides, thought leadership: propositions needing 800 words, not 8. Skip it for simple direct-response offers where long-form friction taxes clicks already earned. A 2026 beta for free-form generation can assemble drafts, but human editing stays mandatory: generated depth with no point of view still reads as filler. Funnel context: the hub primer.
Putting free-form into practice#
Write one 1,500-word teardown this fortnight: problem, method, receipts, objections answered, offer at the end. Thumbnail it with the strongest chart, traffic it to the problem rooms, staff the thread for a week. Depth either converts or teaches; both outcomes pay.
Harvest the thread ruthlessly: objections become FAQ entries, questions become follow-up posts, language becomes ad copy across formats. One great thread supplies a quarter of messaging. Harvesting: comment management and Pro plus paid.
Frequently asked questions#
What is a Reddit free-form ad?
A long-form promoted post mixing text, images, GIFs, video and inline links, modelled on the community megathread.
How long can free-form text be?
The body supports up to 40,000 characters with a 300-character headline; the strongest units read like tight teardowns.
Do free-form ads need thumbnails?
Effectively yes. Without one the ad shows no media in feed, stranding the format best placement.
What results have been reported?
Reddit early testing claimed 28 per cent higher average clickthrough; Canada Goose later reported 10.5 points of awareness lift with 2.58x ROAS.
Should comments stay on?
Yes wherever staffing allows. Depth invites replies, and the replies are both conversion assist and creative research.
How long should the first free-form test be?
Around 1,500 words: deep enough to prove expertise, tight enough to finish.
