What Are Reddit Ad Types?


Reddit offers various ad types to cater to different marketing objectives and engage with its diverse user base. Some of the popular Reddit ad types include:

Text Ads: These simple text-based ads display your message on Reddit. They are easy to create and can be highly effective in reaching a wide audience.

Image Ads: These ads feature an image and a call to action button, making them more eye-catching and engaging than text ads.

Video Ads: Video ads allow you to engage your audience with compelling video content, driving awareness and encouraging action.

Carousel Ads: Carousel ads enable you to share multiple images or gifs in a single ad unit, maximizing ad space and building a deeper relationship with your audience.

Conversation Placements: These ads drive incremental reach beyond the Reddit Feed and engage users when they’re most leaned-in.

High-Impact Offerings: These include high-impact Reddit Takeover, which maximizes your impact with a wide-reaching package, and Category Takeover, which owns top communities in your target category for 24 hours or more.

Reddit’s targeting capabilities are interest-based, allowing you to reach subscribers and visitors of a subreddit based on topics they engage with. You can also choose from various targeting options, such as locations, interests, community, device, and time of day

To create a successful ad campaign, it’s essential to research and become familiar with relevant Reddit ad specs, tailor campaigns to resonate with subreddit subscribers, and test different ad formats, targeting options, and ad copy to see what works best for your business.

How Much Do Reddit Ads Cost?


The cost of Reddit ads is determined by a bid-based system, offering flexibility for advertisers to set budgets based on their preferences. This system operates on a cost-per-thousand-impressions (CPM) or cost-per-click (CPC) model.

Advertisers bid on the maximum amount they are willing to pay for their ads to be displayed or clicked. The specific factors influencing Reddit ad costs include the bid amount, targeting options, ad type, geographic targeting, and ad placement. Advertisers with higher bids increase their chances of securing ad space but may incur higher costs.

Additionally, the specificity of targeting, the chosen Reddit Ad Specs, geographic focus, and premium placements can all impact the overall cost of running Reddit ads. On average, Reddit ads typically range between $0.75 and $2.00 CPM.

It’s important to note that these figures are general estimates, and actual costs can vary based on campaign specifics. Advertisers can set daily budgets to maintain control over spending, and monitoring performance metrics allows for adjustments to bids and strategies over time.

In conclusion, understanding the bid-based system and the factors influencing costs is essential for advertisers aiming to make the most of their budget while effectively reaching their target audience on Reddit.
