tested 4 LinkedIn posting frequencies for 90 days. the sweet spot wasn't what every guru says.
ran the test for a B2B SaaS founder client from january to march. controlled for posting time (8:30-9:30am EST), content type (all text posts under 250 words), and topic mix (60% tactical, 20% personal, 20% commentary). founder's connection base is around 11,000.
the four cadences, run sequentially in 22-day blocks:
- daily (Mon-Fri): 620 avg impressions per post, 1.1% engagement rate
- 4x per week (Mon/Tue/Thu/Fri): 890 avg impressions per post, 1.4% engagement rate
- 3x per week (Mon/Wed/Fri): 1,210 avg impressions per post, 2.1% engagement rate
- 2x per week (Tue/Thu): 940 avg impressions per post, 1.7% engagement rate
3x per week won decisively. on every metric. across the entire 22-day block.
the explanation we landed on. at 5x/week the algorithm distributes each post less aggressively because you're competing with yourself. at 2x/week you don't accumulate enough impressions to compound. 3x hits the spot where each post gets full distribution AND you stay top-of-mind enough to build follower habit.
caveats. n=1 account. sample size is small. industry is B2B SaaS. results may not generalize to larger accounts or different industries.
but the "post every day" advice every LinkedIn guru pushes for the last three years? the data did not back it up for this account. it actively underperformed every other cadence.
planning to re-run the same test on a different account in q2 to see if it replicates.
anyone tested LinkedIn frequency formally? curious if your numbers landed in the same place or if 3x is account-specific.
