The best time to post on LinkedIn (and why the answer is your own data)

Every benchmark chart says Tuesday morning. They agree with each other because they are all averages taken across millions of accounts, most of which have nothing in common with yours. An average built from recruiters in Chicago, software companies in Berlin, and coaches in Sydney describes none of them, and it certainly does not describe an audience of forty specific buyers in your niche.

There is also a second-order problem. If everyone follows the same chart, Tuesday at 9am becomes the most crowded slot of the week, which is the opposite of what the chart promised. Advice that everyone follows stops being an edge and becomes a queue.

What actually determines your best time

• Where your audience physically is, and how spread out their time zones are. A single audience in one country behaves nothing like one split across three.
• Whether they read during work hours or on a commute. Operators and executives check at very different moments than freelancers do.
• How often you post. Frequency affects total reach far more than hour of day, and a bad schedule kept consistently beats a perfect one kept sporadically.
• Whether you are free for the hour afterwards. Early replies drive distribution, so posting time is really availability time.

A four-week test that gives a real answer

Post at one fixed time for two weeks, then shift by three hours and hold that for two weeks. Keep everything else steady: same frequency, similar topics, similar formats. Then compare the median reach of each block, not the best post in each block.

Medians matter here more than most people expect. LinkedIn reach is heavily skewed, so one post that happens to catch a wave will drag an average anywhere you like. If you plan your entire schedule around that one outlier, you have learned nothing and locked it in.

Four weeks is also the shortest window where the noise starts to settle. Anything shorter and you are reading randomness. Anything longer and your topics have drifted enough that you are comparing two different sets of posts.

The part most people skip

Publish when you can answer comments for the following hour. Early conversation is one of the few signals you can directly influence, and it compounds: replies bring the post back into circulation, which brings new readers, who add more replies. Choosing a mathematically optimal slot that lands in the middle of your client calls is worse than a mediocre slot where you are actually at your desk.

Fixed scheduling in Run More Posts exists mostly to make this comparison possible. If your posting time moves around randomly, you can never tell whether a change in reach came from the timing or from the writing.
