Reddit ads without posting: reach the right people and stay out of the threads

Reddit advertising series · Part 2 of 3

In Part 1 we looked at why Reddit matters: a huge UK audience, people who arrive with a purpose, and conversations that shape what AI tells your customers. Now for the practical part. How do Reddit ads work, what do they cost, and what do you actually need to do?

The short answer to that last question: a lot less than you might think.

You target conversations, not just people

On most platforms, you target people by age, location and interests. Reddit has those options too, but its real strength is context. Reddit is made up of communities, called subreddits, each built around one topic, from running to recruitment software. That means you can put your ad in front of people while they’re reading about exactly the thing you sell.

Context pays off. Reddit’s research with WPP Media found that targeting by community drives up to 16 times higher purchase intent than keyword targeting alone. People are also 30% more likely to engage with ads that appear in relevant communities than with ads elsewhere.

What Reddit offers B2C brands

Reddit has the ad formats you’d expect: image ads, video and carousels. It also has free-form ads, which mix text, images and video in one post, so they read like a Reddit post rather than a banner. According to Reddit, free-form ads get a 28% higher click-through rate than its other formats.

For online shops, the big one is dynamic product ads. They pull products straight from your catalogue and show people the ones that match their interests. Since their full launch in May 2025, Reddit says they’ve delivered about twice the return on ad spend of standard conversion campaigns. Collection ads were added in March 2026, and Reddit’s Shopify integration went global in May 2026, so connecting a Shopify store is now much simpler.

Two studies cited by Reddit on its latest earnings call back this up. Research by Circana for Attain found Reddit delivered 1.5 times the return on ad spend for consumer goods brands compared with other social platforms. And a TransUnion study named Reddit the most efficient paid social channel for retail across Europe, the Middle East and Africa.

What Reddit offers B2B brands

Business buyers do their homework. A survey of 1,202 US business decision-makers by SurveyMonkey and Reddit found that 83% research on their own before speaking to a salesperson. Their most trusted source is recommendations from peers (73%), and 32% of software buyers use Reddit for their research.

Reddit now has the tools to reach them:

• Business targeting through Bombora. 6,300 B2B attributes, such as company size, industry and job function, plus 19,000 “Company Surge” audiences of businesses actively researching a topic.
• Lead gen ads. A sign-up form inside the Reddit app, with the email address filled in automatically, that can send leads to your CRM through Zapier. In testing, the software company LaunchDarkly cut its cost per lead by 30% and got 25% more sign-ups.
• Keyword targeting on the problems you solve. Reach people discussing your competitors or asking for help with the exact problem your product fixes.

And for B2B marketers, the cost difference is hard to ignore.

What it costs

Reddit is one of the more affordable platforms to advertise on. 2026 industry benchmarks put a typical cost per thousand impressions (CPM) at around $3 to $12. That’s in line with Meta and TikTok, and a fraction of LinkedIn.

Cheap impressions only matter if they reach the right people, of course. That’s where Reddit’s targeting earns its keep. You’re not paying less for a worse audience. You’re often paying less for people who are actively looking.

Automation has caught up

One reason some marketers held back from Reddit was that it felt manual compared with Google or Meta. That’s changed. In September 2026, Reddit opened its Max campaigns to all advertisers. Like Google’s Performance Max, they automate targeting, creative choices, placements and budget, within limits you set.

Max campaigns also include a report called Top Audience Personas, which shows who is engaging with your ads and what motivates them. That’s useful insight for the rest of your marketing, not just Reddit.

Advertisers are noticing. Reddit reports that conversions from its ads doubled in a year, and the number of active advertisers grew 70%. The early-mover window is still open, but it won’t stay open for ever.

You don’t have to join the conversation

This is where a lot of marketers stop. They assume Reddit means building a community, posting every day and replying to strangers. It doesn’t. You can advertise on Reddit without ever posting or commenting.

When a Reddit ad is set up, you choose whether people can comment on it. For most clients, we switch comments off. The ad still reaches the right people and sends them to your website. It just doesn’t open a public thread that someone would need to watch and answer.

For some businesses, advertising only is simply the better choice. Redditors are quick to call out anything that feels like marketing, and a brand account that turns up in threads uninvited can do more harm than good. If you work in a regulated sector, or don’t have someone free to answer questions, an open comment thread is a risk rather than an opportunity.

If you do decide to talk to Redditors later, it should be you, not an agency. You know your products and customers better than anyone. It can pay off, too: 58% of Redditors say seeing brands respond directly in threads makes them trust the brand more. Reddit even offers a free set of tools, Reddit Pro, for businesses that want to take part. But it’s an option for later, not a requirement.
