Reddit Ads: How to advertise on Reddit?

Reddit advertising is an unmissable opportunity today.
Created in 2005, Reddit was initially built around scientific and technical communities. Its participatory model—based on user-voted posts—quickly established Reddit as an influential space for experts and enthusiasts alike.

Several key moments have marked its growth:
- In 2010, the decline of its competitor Digg triggered a massive influx of users;
- In 2012, Barack Obama joined the platform during his presidential campaign to reach a new audience. Much like our Macron with McFly and Carlito on Twitch 👀.
- In 2021, the GameStop saga, driven by Redditors, shook Wall Street.

Today, Reddit claims over 500 million monthly users worldwide (source: Statista) and nearly 100 million daily active users. Yet, Reddit advertising remains largely underutilized by brands, especially in France.

👉 This imbalance between ad supply and demand makes CPMs particularly competitive. Additionally, Reddit offers a subscription service, Reddit Premium, at $59.99/year, which contributes to its growth.

So, why should you consider advertising on Reddit now?
We’ll tell you everything 👇

Reddit Ads: Why use them?

Reddit isn't just a hub for memes or heated debates. It is primarily an ecosystem of highly targeted communities, known as subreddits, where users share their passions, problems, and questions.

It is an ideal environment for a brand looking to reach a specific audience in a contextualized way.

Reasons to consider Reddit advertising:

✅ A global reach with over 100,000 active communities across all fields (gaming, tech, music, health, cinema, etc.)

✅ An audience known for being engaged, curious, and discerning

✅ A space not yet saturated with ads, meaning costs remain affordable

✅ Powerful targeting capabilities, on par with the best platforms

How do you advertise on Reddit?

Reddit offers several ad formats that integrate seamlessly into the site's native environment:

- Feed ads : these appear on the home page or within subreddits, just like a regular post
- Comment ads : these are inserted directly under discussions, in a way that is discreet yet visible
- Custom format : a customizable ad combining text, visuals, GIFs, or videos – ideal for creating an immersive, native experience

How does targeting work on Reddit Ads?

Reddit Ads offers a fairly simple campaign creation tool, with a range of advanced targeting options:

🎯 By interest or subreddit : Reddit lists thousands of active communities, each with an estimated user volume. For example, by typing “gaming,” you will see subreddits like r/gaming or r/pcgaming appear, along with their estimated audience size.

Reddit Ads: What performance can you expect?

You can optimize your Reddit ads based on several objectives 🎯:

- Awareness and reach where the primary KPI is CPM (Cost Per Mille)
- Website traffic with a CPC (Cost Per Click) KPI
- Video views with a CPV (Cost Per View) KPI
- Conversion with a CPA (Cost Per Action) KPI. This could be a visit, an add-to-cart, or a purchase, for example.
- App installs with a CPI (Cost Per Install) KPI.

How much does Reddit advertising cost?

We can launch a Reddit ad campaign starting at €1,000 at Klox, with a small caveat regarding the minimum daily budget, which is €30 per day. 💰

The costs are still low, mainly because few French brands are present there. It’s a great time to test Reddit ads.

Best practices for a successful Reddit ad campaign

Reddit is not Meta or TikTok. It has its own unique codes and tone. To make your campaigns work:

✅ Adapt your tone to the targeted subreddit : avoid marketing jargon or overly salesy promises

✅ Prioritize transparency and humor : it performs much better

✅ Test multiple versions (headlines, images, formats) using A/B testing

✅ Keep an eye on the comments : Reddit can be harsh, but it is also a valuable source of feedback
