LinkedIn engagement rate calculator
Work out your engagement rate, see it under every competing formula, and compare it against the benchmark for your follower band rather than one platform average that fits nobody.
Free, no account. The fix-by-fix rewrite guide arrives by email
Post Reach Score
Paste a LinkedIn or X draft and get a reach-readiness score: AI-writing tells, weak hooks, missing specificity, engagement bait. Every issue quotes the text that triggered it.
