YouTube Ads vs Reddit Ads: Broad Video vs Community Targeting

In short: Both reach people through content they're already engaged with instead of a search box, but the unit of relevance is different. Reddit sells relevance at the community level - you target a subreddit or interest, and the comments under your ad become a visible, public verdict from that community. YouTube sells relevance at the individual level using Google's behavioral and viewing data, bought inside Google Ads alongside Search, with formats from a 6-second bumper to long in-stream video. Pick Reddit when your product has a genuine, active community and you can match its tone; pick YouTube when you want broader scale, more format range, or a shared account with your Google Ads Search campaigns.

Reddit Ads

Places ads inside specific subreddit communities and feeds, letting you target by community interest rather than by personal profile data.

Community-targeted advertising where the unit of relevance is the subreddit rather than the individual, which makes it useful for niche technical, hobbyist, and B2B audiences at relatively low cost. The common mistake is corporate tone: users publicly criticize ads that ignore community norms, and those comments sit attached to the ad, so match the register or turn commenting off deliberately.

YouTube Ads

Video advertising bought inside Google Ads, covering skippable and non-skippable in-stream, in-feed, Shorts, bumper, and masthead placements across YouTube.

YouTube inventory is purchased through Google Ads campaigns rather than a separate console, so it shares Google's audience, bidding, and measurement stack. It works for building demand at low cost per view and for cheap retargeting of known audiences. The common mistake is measuring it on last-click reporting, which credits the later search click and makes video look worthless.

Side by side.

The differences that actually change what happens in your account.

	Reddit Ads	YouTube Ads
Unit of targeting	The subreddit or community itself, chosen by topic relevance.	The individual viewer, via Google's audience and behavioral signals plus video content or topic.
Ad format	A native-looking promoted post or card, mostly static or text and image with some video.	Video-first, across multiple placements including in-stream, in-feed, Shorts, and bumper.
Public response exposure	Comments attach directly beneath the ad and are highly visible; the community can upvote, downvote, or criticize publicly.	Comments can appear under a video ad but carry far less weight in how the ad performs.
Cost environment	Relatively low CPMs and CPCs due to a smaller advertiser base competing for the inventory.	Cost varies more by targeting tightness and format, reflecting a much larger advertiser base.
Best-fit audience	Niche technical, hobbyist, gaming, and B2B communities with strong, stated opinions.	General consumer reach plus retargeting of people who've already engaged with your content.
Buying environment	A standalone Reddit Ads Manager with its own pixel and conversions tracking.	Inside Google Ads, sharing infrastructure with Search.
Brand tone requirement	Must match the community's register or risk visible, public backlash in the comments.	Broader tolerance for a polished, conventional advertising tone.

What actually separates them.

Reddit sells relevance at the community level - you choose subreddits or interests - while YouTube sells relevance at the individual level using Google's broader behavioral and search history data.

A Reddit ad's comment section is part of the ad's public face and can turn into a visible community verdict on the brand; a YouTube ad's comment section carries far less structural weight in how the ad performs.

YouTube inherits Google Ads' Smart Bidding and conversion tracking, so the same account can move budget between Search and YouTube; Reddit's bidding and reporting live entirely inside its own separate tool.

Reddit's inventory is comparatively cheap because fewer advertisers compete for it, while YouTube's cost reflects the much larger advertiser base bidding across the Google ecosystem.

Reddit ads succeed by reading as a genuine community post, down to tone and willingness to engage with replies; YouTube ads succeed on watch-time and completion signals the algorithm tracks regardless of tone.

Which one should you use?

Use Reddit Ads when

You sell into a niche technical, hobbyist, gaming, or B2B category with an active, opinionated subreddit.
You can write and moderate in a tone that matches the community rather than sounding like corporate copy.
You want low-cost testing before committing real budget to a bigger channel.
You're comfortable with public comments sitting under your ad and want to engage with them rather than hide them.

Use YouTube Ads when

You want video reach that shares an account, audiences, and bidding with your existing Google Ads Search campaigns.
Your category doesn't map to a specific, active online community but does map to broader interest or in-market signals.
You need multiple funnel stages - awareness, consideration, retargeting - inside a single platform.
You want a channel with more scale and more predictable cost-per-view than a niche community platform offers.

Common questions.

Should I turn off comments on a Reddit ad?

It depends on your capacity to moderate. Disabling comments avoids the risk of public criticism sitting under your ad, but it can also read as evasive to a community that expects to be able to respond, so weigh that trade-off deliberately rather than defaulting to it.

Is Reddit only good for B2B and tech products?

No, but it's strongest there. Any product with a genuine, active subreddit community can work - the deciding factor is whether that community exists and is engaged, not the product category itself.

Why is my YouTube cost per view higher than expected?

Usually broad or highly competitive targeting is the cause. Narrowing placements or switching to a cheaper reach-oriented format like bumper or Shorts, rather than in-stream, typically brings cost per view down for the same audience.

Can I run the same ad copy on Reddit as elsewhere?

Not recommended. Reddit's community tone matters enough that generic ad copy tends to get called out publicly, so rewrite for the specific subreddit's register rather than reusing copy built for a broader platform.

Or stop choosing between them.
