What we measure, written down.
The Sonar blog is where we publish what we measure. Studies run on public LinkedIn posts, notes on writing in your own voice, and the working details of turning a founder's week into drafts they are willing to put their name on.

Every post names its method before its conclusion. Where a number comes from public data we say how much data, from when, and what it cannot tell you.

Build the calendar from your week, not from a theme list
Most LinkedIn content calendars fail in week two because they were invented in advance. Here is one built backwards from the week you were already going to have.
- LinkedIn
A normal week holds more posts than you think
Count the moments in one ordinary working week using a printed rule, and see why the founders who run dry are usually looking in the wrong place for material.
- Personal branding
How to build a personal brand on LinkedIn without posting about yourself
The accounts people actually follow are not autobiographical. They are built from the work, the positions and the numbers, and the person comes through anyway.
- Founder-led
Founder-led content is not the founder posting
The phrase gets used for any post with a founder's face on it. The distinction that matters is whether the material could have come from anyone else in the company.
- LinkedIn
Members reached tells you more than impressions do
LinkedIn reports impressions and members reached as two different numbers. One counts screens, the other counts people, and the gap between them is worth reading.
- LinkedIn
Posting consistently when your week is all meetings
Consistency does not break for one reason, it breaks in four specific ways. Each one has a different fix, and none of them is trying harder.
- Comparison
Taplio vs Supergrow, compared on what each one asks of you
Both are good at what they do and both start from a blank box. Prices read from their own sites on 22 September 2026, plus an honest note on where we fit, since we sell the alternative.

What a LinkedIn ghostwriter actually costs
Three public pricing guides, read and compared: what founders pay a LinkedIn ghostwriter per month and per post in 2026, what moves the number, and what the fee cannot buy.

What counts as a good impressions number on LinkedIn
Nobody can tell you a good impressions number without knowing your follower count. Here are the two comparisons that do work, and the arithmetic behind them.

How Sonar keeps your colleagues out of your LinkedIn posts
A colleague, a client or a candidate reaches a Sonar draft as a role and never as a name. Here is where that rule lives in the code, and where it stops.
- Voice
How to write LinkedIn posts that sound like you
How to write LinkedIn posts in your own voice: measure the rhythm of your real posts in numbers, hold every draft to them, and stop describing it in adjectives.

The nine hook types in 918 top founder LinkedIn posts
We labelled 918 high-engagement public LinkedIn posts by hook type and ranked them by median engagement. The gap between the best and the worst is narrow.

Why your LinkedIn post should not be your X post
Publishing in both rooms does not mean two personalities. Here is what changes between LinkedIn and X, what never changes, and the same idea written for both.

What to post on LinkedIn after a client call
A client call gives you four things that are safe to publish: a pattern, an objection, a number and a decision. How to write each without identifying anyone.
The posts explain it. Sonar does it.
Sonar reads your calendar, meetings, Slack and notes once a week, keeps the moments worth saying, and writes drafts in your voice for you to approve. How it works is the mechanism, and the LinkedIn personal branding guide is the habit it runs.
