Why LinkedIn for an expert
LinkedIn is the only mass platform where people show up with a work mindset. They're already thinking about work, budget, hiring and projects. That's a rare luxury for a sales channel.
Content structure
Split your feed into three types: expert (what you do), case (how it worked) and personal (why you can be trusted). Without personal posts you stay 'one more expert'; without case posts you stay a theorist.
Rhythm
Two posts a week for a year beats seven posts a week for a month. The algorithm and the audience both reward consistency. Burnout kills the channel faster than a bad post.
Inbox
Leads come from DMs, not likes. Set a rule: reply within 24 hours and move the conversation to a call as soon as you see a job to be done. Most lost leads are lost in the inbox.
