The Myth of the Best Time to Post

Every year, SaaS companies publish massive studies analyzing millions of posts to declare that "Tuesday at 11 AM" is the optimal time to post on LinkedIn. It is entirely meaningless.

These studies suffer from severe survivorship bias. If every scheduling tool defaults to suggesting Tuesday at 11 AM, and every marketer blindly accepts that suggestion, then the highest volume of posts (and consequently, total aggregate engagement) will occur on Tuesday at 11 AM. It is a self-fulfilling prophecy.

The Algorithmic Reality (2024)

Timeline chronologies have been dead for years. The half-life of a LinkedIn post is currently estimated at 48 hours. A Twitter (X) post might have a half-life of 20 minutes, but it can resurface 3 days later if quoted by a high-authority account.

Platform	Primary Feed Logic	Timing Importance (1-10)
LinkedIn	Dwell time, comments within first 60m	4
X (Twitter)	Velocity, verified account interaction	8
Threads	Interest graph, mutual follows	2

What Actually Matters

1. Dwell Time: Did they stop scrolling? Did they click "see more"? This signals to the algorithm that your content is valuable, regardless of when it was published.
2. Early Velocity: While absolute timing matters little, the reaction of the first 100 people who see it matters immensely. If you post when your specific community is asleep, the post dies in the crib.
3. Substance: A platitude posted at 11 AM on Tuesday will perform worse than an insightful, contrarian analysis posted at 11 PM on a Saturday.
