Subreddit targeting is too narrow, your ICP isn’t always in the right communities, and Reddit’s reporting doesn’t tell you what’s driving pipeline.
Primer fixes this by letting you build high-match audiences, so you can reach your ICP across all of Reddit and measure real company-level impact.
Prerequisites:
Pixel installed
Reddit Ads connected
CRM connected (optional)
Step 1
Build Your ICP Audience in Primer
Warning:
Match rates vary dramatically by persona — as high as ~80% for IT and engineering, but as low as ~5% for finance or procurement. Reddit is still a niche B2B channel compared to Google, Meta, and LinkedIn, so audience size will depend heavily on who you’re targeting.
Step 2
Launch Reddit Campaigns with Primer Audiences
Create campaigns using Primer audience targeting for broad Reddit reach outside of specific subreddits
Optional: If you want a more constrained approach, layer Primer audiences with subreddit targeting.
Best practices:
Use in-feed placements only (avoid audience network / low-quality inventory) Separate campaigns by Audience and ad sets by creative format since creative optimization needs to be done manually.
Step 3
Develop Native Reddit Creative
Use formats like freeform posts (look like organic content), short-form video (lo-fi, native feel), link posts
Advanced tactic: Leave comments enabled. Engage directly with users in-thread.
Tip:
Reddit doesn’t support native creative rotation well — you need to split ad groups by format to control spend and test performance, making experimentation more manual.
Principle
Impact
Subreddit targeting is limited
Primer enables scale across all of Reddit
Reddit users use personal emails
Primer improves match rates for targeting + exclusions
ICP behavior is non-linear
You reach buyers outside obvious contexts
Reddit is not last-click
Focus on pipeline influence instead
Native content wins
Better engagement and lower resistance
Step 4
Optimize & Measure Performance
Optimize using short-term signals like de-anonymized website visits that tell you if the traffic from Reddit is from within your ICP. Expect last click conversion volume to be limited.
Measure long-term impact in Primer by tying Reddit exposure (i.e. site visits from reddit) to pipeline and revenue at the company level.
tl;dr - Don’t rely on last-click attribution — focus on whether Reddit is influencing high-quality accounts and driving pipeline over time.
Key Metrics:
Visits & site engagement from in-ICP companies
Pipeline created after exposure
What to expect
Reddit is early for B2B — results vary, but upside is high.
