Are Reddit ads worth it for B2B SaaS lead generation?

By The Tofu team ·

Use Reddit if your buyers are practitioners who discuss tools in subreddits (developers, IT, security, data), your offer converts on your website, and you can track leads with the Reddit Pixel or Conversions API. Use LinkedIn or Google first if you need job title or named-account targeting, want leads without a website visit, or can't spend about $3,000 on a four-week test. Reddit's API change log says onsite lead forms are no longer supported, with ads using them paused from September 30, 2026. On October 6, Reddit added Max campaigns for lead generation, in-market audiences and B2B data partners.

As of October 2026.

If you sell to practitioners who talk shop on Reddit

This is Reddit's strongest case. It says "more than 20 million business decision-makers come to Reddit" globally (citing Bombora, March 2025).

OptionWhat Reddit says
Community targetingReaches people who subscribed to, viewed or visited your chosen subreddits in the last 28 days, wherever they browse on Reddit. Use at least 15 communities per ad group
Keyword targetingContent containing your keywords, in six languages, up to 1,000 keywords per ad account. Reddit says it drives "better lower funnel performance than other Reddit audience options"
PlacementsFeed, and Conversation (the comment page, including people arriving from a web search). Reddit recommends both
Automated targetingOn by default. Your keywords, communities and interests become suggestions, not limits. Location, language, device and exclusions still hold

If you need job titles, seniorities or named accounts

Reddit's own targeting has no job title, seniority, employer or company size option. Its October 6 partners fill part of the gap: Bombora, Demandbase, Clay, G2 "through the Bombora connector," and Octane11.

  • Bombora says Reddit advertisers can use 25,300 Company Surge intent audiences, more than 6,300 B2B attributes and key account lists. Neither Reddit nor Bombora publishes the price.
  • Clay syncs contact lists to Reddit as customer lists, matched on email or mobile advertising ID.
  • Custom audiences made in Ads Manager need between 1,000 and 1 million matches, and a customer list can take up to 24 hours to process.

To reach specific roles at specific companies, LinkedIn is still the direct route. For another channel without firmographic targeting, see whether ChatGPT ads are worth testing for B2B lead generation.

If you want leads without sending people to your site

Not on Reddit, for now. Reddit's Ads API change log says:

  • September 21, 2026: the Lead Generation Forms API "will be sunsetted as onsite forms will no longer be supported." Advertisers must move to forms tracked with the Reddit Pixel or Conversions API.
  • September 30, 2026: creating a form through the API returns an error, and "existing ads using onsite forms will be paused." Form and lead retrieval "remain available," but Reddit's API migration guide says to retrieve data before the sunset, so download old leads now.

Those notices are for API developers. Reddit's Ads Manager help now describes lead generation campaigns only as "driving users to a form on your website," optimized for Lead or SignUp, or Clicks if you haven't set up the Pixel or Conversions API, with image or video ads.

If you use HubSpot

Turn on HubSpot's Reddit Ads integration (beta; a Super Admin opts in). In HubSpot settings, go to Marketing > Ads, open the Ad accounts tab, click Connect account and select Reddit Ads. You need the Admin or Creator role in Reddit Ads. With auto tracking on, HubSpot adds UTMs such as utm_source=reddit and shows which contacts and deals came from Reddit.

Reddit calls HubSpot an open beta partner "for attribution, reporting, and account setup" and says "Pixel and Conversions API implementation is planned for later this year." Until then, send lead events with the Pixel or Conversions API, directly or through a listed partner such as Google Tag Manager, Segment or Hightouch.

If you judge channels on pipeline

  • Use the Pixel and Conversions API together. Reddit recommends this "for best performance" and requires deduplication when you do. Conversions API events "must be sent within seven days after they occur."
  • Compare like with like. Reddit's recommended default credits conversions up to 28 days after a click and 1 day after a view. For click-only comparisons, switch in Events Manager > Attribution Settings > Edit.
  • Choose the conversion goal carefully. Reddit says the Pixel, conversion goal and optimization window "can't be changed later."
  • Judge on qualified pipeline in your CRM, the same test as for whether Google Ads is worth it for B2B SaaS.

If you have a small budget

Reddit says "each ad group should have a daily budget of at least $50," and suggests tests of at least four weeks with two or more ad groups: about $2,800. New ad groups need "around 20 optimization events" to leave the learning phase. Target cost bidding needs at least 200 events in the last 28 days, and cost cap ends for lead generation on February 10, 2027.

Reddit doesn't publish average costs. Refine Labs' Q1 2026 benchmarks (April 1, 2026), from its managed accounts running brand awareness campaigns, put Reddit at $9.33 per 1,000 impressions and $3.11 per click, up 36.8% and 67.3% year over year, against LinkedIn's $42.29 and $11.24. Those are awareness figures; we found no B2B cost per lead from Reddit or a large independent source.

If you want proof from other B2B advertisers first

The published numbers are Reddit's own, and only one is B2B:

ClaimWho says itBasis
Max campaigns: 17% lower cost per result, 27% more resultsReddit's Max campaigns pageSplit tests from June to August 2025 (17 tests, per Reddit's September 3, 2026 post), each comparing Max with standard campaigns over 21 days
In-market audiences: "an average improvement of nearly 7%" in cost per acquisition versus other first-party targetingReddit, October 6, 2026Reddit internal data, August 2026
Huntress (cybersecurity) cut its cost per acquisition by more than half; 40% of sales-qualified accounts Reddit sourced in a year became opportunitiesReddit, October 6, 2026One advertiser, two campaigns, community targeting

In-market audiences are in beta and come "automatically through Max," in categories such as Enterprise and Business AI and Cybersecurity. Max uses image and video ads only. Reddit's September 3 post made Max "available to all advertisers," but its Max page still says "some advertisers might not have access yet," and its help calls Max a beta.

If you decide to run a test

  1. Install the Reddit Pixel and Conversions API, and send a Lead or SignUp event from your form.
  2. Pick one offer for people still researching, such as a free trial or a template, not a cold demo request.
  3. Create a Standard lead generation campaign with two ad groups, one using community targeting and one keyword targeting, on feed and conversation placements.
  4. Exclude customers with a customer list, if it reaches 1,000 matched users.
  5. Set a lifetime budget of about $2,800 and a four-week end date. Reddit recommends a lifetime budget "if you have a smaller budget."
  6. Wait at least two weeks before judging targeting, as Reddit advises, then compare qualified pipeline per dollar across channels.

What to avoid

  • Optimizing for clicks because the Pixel isn't set up.
  • Reading the community report as placement data. Reddit says a community in your report "doesn't mean your ad ran there."
  • Turning on comments with no one to reply. Comments are off unless you tick Allow comments on Reddit post.
  • Editing during the learning phase. Bid or budget changes of more than 20% can restart it.
