Reddit Ads for B2B on a small budget: a real channel or expensive curiosity?

I've been reading up on Reddit Ads for B2B software and still can't tell if it's a real channel or just a fun way to burn a few hundred dollars. The case for it is that people in role-based subreddits are often in research mode, and community targeting can be more specific than anything you get on Meta. The case against is that CPMs look cheap, but click intent is thin and plenty of people are there to read, not buy. My leaning is to test it with one clear offer aimed at one narrow community, say a finance tool for a particular accounting subreddit, and judge it on booked demos instead of clicks, since CTR would mostly reward curiosity. Has anyone run it on a small budget and gotten a number that actually meant something?

Judging it only by booked demos won't tell you much. At a few hundred dollars you'll probably get two or three, which is too few to read anything from. Add a nearer step like pricing page visits or sign-ups, and agree on a cost-per-action bar before launch.

Sample size is a real problem here, so I'd go with the nearer step as the main metric. A rule that helps: set your cost-per-action ceiling as a multiple of what a booked demo is worth to you, say 3x, and kill the test if you're above it after a few hundred clicks. That way you have a number to stop on instead of a gut feeling.

A 3x stop line is a good one, but do the math before you launch. If a niche sub's CPC lands around a few dollars, a few hundred dollars buys maybe 100 to 150 clicks. At a 3 to 5 percent pricing-page rate, that's only a handful of events, and at that size you can't tell a real 3x miss from plain bad luck. A rule of thumb that helps: work backwards from your budget to a click count, and if it comes out under about 300, either raise the test budget or put all of it into one community. Splitting a small budget three ways just gets you three unreadable tests.

I'd drop the 300-click floor and count expected events instead. At a 3 to 5 percent pricing-visit rate, 300 clicks only gets you 9 to 15 visits, which is too noisy to tell whether you're really off by 3x. Use the first round to see whether the community clicks at a sane CPC, and save the cost-per-action call for later.

Your expected-events math holds, but the 3 to 5 percent input is doing a lot of quiet work. That rate usually comes from warm traffic like search or retargeting. Cold readers clicking through from a subreddit are probably closer to 1 percent on a pricing page, and some communities will run lower. At 1 percent, 300 clicks gets you about three visits, and no stop rule can read that.

So I'd treat the first round as a measurement of click-to-visit rate, not a verdict on the offer. Before spending, make sure the pixel fires on the landing page and the pricing event is actually being counted, because a broken tag looks exactly like a dead audience. Then compare what you see to the rate you assumed. If it's far below, set the stop line from the observed rate and the budget you're willing to lose, not from the number you started with.

Agreed, and the tracking check matters even more on mobile. A lot of Reddit traffic comes from the app, and many in-app browsers load scripts slowly or block them, so a pixel can miss sessions even when everything looks fine on desktop. Tap your own ad on a phone, click through to the pricing page, and make sure the event shows up in the platform's events view before you put real budget behind it.

Agreed, and the redirect chain matters too. If your ad link runs through a shortener or a tracker that strips parameters, the pixel can fire on the wrong URL or not at all. Compare Reddit's conversion count against your analytics sessions for the same landing page before you scale, so you know which side is leaking.

Agreed, and make sure you're only comparing click-through conversions. Reddit's reporting can also count view-through conversions, and those people never clicked, so the gap against your analytics sessions will look off.
