What six months of consistent LinkedIn posting actually did for inbound

In January 2025, I made a commitment that I would post on LinkedIn at least three times a week for the whole year. No excuses, no "I will start when things slow down," just a repeating calendar block and a 200-word minimum. It is now July. I have missed about six posts total.
I have been tracking every inbound contact form submission and new inquiry call to ask one question as early as naturally possible: how did you hear about us? The LinkedIn attribution numbers surprised me, in both directions.
What LinkedIn has done well
Brand recognition among warm contacts. The strongest pattern I see is not cold leads finding us through LinkedIn. It is people who already knew the name from a referral or a Google search, who then looked us up on LinkedIn before contacting us. LinkedIn functions as a trust verification layer, not a discovery engine. The post history gives them something to read. The consistency gives them a sense of what we are actually like to work with.
I have had three inbound calls this year where the person mentioned a specific post before anything else. One of them became a client. That conversion from a specific post to a client is real value, but it is not the same as LinkedIn directly generating leads. The post accelerated a conversion that was already possible because they found us through other means first.
Network reactivation has also been real. People who knew me from a previous context, former colleagues, people I had met at events, reconnected via comments or DMs. Two of those turned into project conversations. One became a referral for something we actually took on.
What LinkedIn has not done
Cold lead generation. I have not had a single inbound that was genuinely cold, where someone found my LinkedIn profile independently, read a post, decided we were the right agency, and sent us an inquiry. That pattern may exist for LinkedIn creators with large audiences. It has not materialised for us at our current follower count of around 2,800.
I was also hoping LinkedIn would accelerate the time from first contact to proposal. I do not have evidence that it has. Clients who found us through search take about the same time to move through the sales process as clients who came via referral.
The honest accounting
LinkedIn is worth the investment. Three posts a week is maybe two to three hours of actual work per week including thinking about what to write. The network reactivation value alone has probably returned that time investment.
But if you are posting on LinkedIn hoping it will replace other lead generation channels, it will not. Not at the start. The compounding is real, but the compounding timeline is long and the mechanism is indirect. More like a long-term brand asset than a sales channel.
I am going to keep going. I am also going to stop expecting it to do something it is not designed to do.
