What Is a Conversation Ad?
Conversation Ads are a Reddit specific ad format that places sponsored content inside or right above an active comment thread. Instead of waiting for the user to scroll past in the feed, the ad lands inside the moment the user is most engaged: reading a discussion they care about. The format launched in 2021 and has become one of the highest converting placements on the platform for brands that know how to use it. It exists on Reddit because Reddit is the only major social platform built around long form conversation rather than personalized discovery, which gives Conversation Ads access to consideration moments other platforms cannot reach.
The placement matters. Standard feed ads, including Promoted Posts, reach users who are scrolling and may or may not be in the right mindset for your category. Conversation Ads reach users who have actively chosen to read about a topic, which is closer to search intent than to social interruption. The intent quality is meaningfully higher even though both formats run on the same paid platform.
Why Do Conversation Ads Convert So Well?
Reddit users open a comment thread because the topic already matters to them. They read multiple comments, weigh different opinions, and often arrive at the thread through search rather than the feed. Putting a sponsored message inside that moment is closer to a search ad than to a social interruption, which produces conversion behavior closer to paid search than to paid social. Conversion rates on properly targeted Conversation Ads regularly run 1.5 to 3 times the conversion rate of Promoted Posts in the same campaign on the same audience.
Most brands skip Conversation Ads because the format requires more thought to use well. The brands that figure them out get higher click through rates and lower cost per acquisition than they get from Promoted Posts in the same program. Conversation Ads also stay relevant longer because they live tied to specific threads and topics rather than being purely feed driven, which means a successful ad can keep producing conversions for as long as the underlying conversation remains active.
When Should You Use Conversation Ads?
Direct response campaigns where the offer needs to land at the moment of consideration are the strongest fit. A user reading a thread about “best CRM for small business” is closer to a buying decision than the same user scrolling their feed casually, and Conversation Ads put the brand inside that decision. Comparison content like vs pages, alternatives content, and switching guides perform especially well as Conversation Ads because the user is already comparing options and ready to evaluate.
Question targeting is another strong use case. Reddit threads phrased as questions are perfect placement for an answer led ad that addresses the exact question the user clicked into to read. Lower funnel retargeting, when paired with pixel based audiences, is the third strong use case. Users who visited the site but did not convert can be reached again through Conversation Ads when they show up reading relevant threads, which produces some of the highest converting retargeting placements available on any platform.
What Are the Common Mistakes That Underperform Conversation Ads?
The most common is using generic creative not tailored to the conversation. Conversation Ads work best when the creative addresses the specific question or topic the thread is about. A generic brand ad that could appear anywhere will underperform a tailored ad that speaks to the conversation at hand. The second mistake is broad targeting. Conversation Ads reward narrow, intent matched targeting more than feed ads do, because the placement value depends on the relevance match between ad and conversation.
The third mistake is treating Conversation Ads like Promoted Posts in budget allocation. The format usually needs less spend to produce results because the audience is more qualified, but it also has less inventory available because not every thread has space for sponsored placement. Splitting budget thoughtfully between Promoted Posts (volume) and Conversation Ads (intent) usually outperforms putting all spend in one or the other. The fourth mistake is ignoring the comment section once the ad runs. Like Promoted Posts, Conversation Ads have engagement value that compounds when the brand actually engages in the comments.
How Do You Set Up Conversation Ads That Pay Back?
Build the campaign inside Reddit Ads Manager and choose the Conversation placement specifically rather than letting Reddit auto distribute. Target by subreddit for the highest intent signal, then layer in keyword and conversation targeting for related threads on broader subreddits. Creative should answer the question the thread is asking. Generic brand messaging is the fastest way to waste budget on this format. Refresh creative every two to three weeks because frequency caps and creative fatigue apply here too.
If you want the format used correctly inside a full funnel program, our Reddit Ads Management service runs Conversation Ads alongside Promoted Posts and video so each format does the job it is best at, with the broader Reddit work coordinated through Reddit Marketing and the integrated paid program inside our Growth and Acquisition solution. For related concepts, see Subreddit, Promoted Post, Reddit Pixel, and Remarketing. The bottom line: Conversation Ads reach users at the moment they are deciding. Most paid programs leave that moment to chance. The ones that do not extract significant outperformance from the format.
