Original posts in your voice on the topics your buyers ask about, spaced across the month, published from your own profile after you approve them. LinkedIn does not expose search, so this lane is about being consistently worth reading.
One or two posts a week per profile, more once trust is earned.
Every agent publishes through the same gate: the warming lane, per-account and per-community caps, the 90/10 rule, community rules and your approval. The whole design is public.
