Questions people ask.
- Who is Mark Lobosco?
- Mark Lobosco is Chief Business Officer at LinkedIn. This independent study examines his public LinkedIn activity between June 25 and September 25, 2026.
- How often does LinkedIn's Chief Business Officer post?
- He published nine original posts in 13 weeks, or about three a month, plus one co-authored post. His publishing clustered around company moments rather than following a steady weekly cadence.
- What formats does Mark Lobosco use?
- Every post in the window used media or a link. Four were videos, three used a photo, carousel or graphic, and two used link cards. There were no text-only posts.
- What made his breakout LinkedIn post different?
- The September 8 selfie video opened with a question, used one clear statistic, stated a short people-trust-people thesis, named creators and ended with both a research link and a request for comments. It received 7,588 reactions, 11 times the next-best post.
- Does Mark Lobosco repost other people's posts?
- No reposts appeared in the study window. Instead, he left 13 comments on 12 other people's posts, usually short, specific and written within a day or two.
- Is the study free?
- Yes. Enter your email and the seven-page PDF downloads immediately. The report uses public LinkedIn activity only and states its method and limits.
Mark Lobosco leads LinkedIn's business organization, which makes his own use of the platform a useful executive-content case study. The pattern is not high-volume publishing. It is selective original posts around company moments, direct participation in other people's conversations, and one unusually large research-led breakout.
The report separates what happened from what can responsibly be inferred. It describes a 13-week public snapshot; it does not claim that one executive's schedule is universal advice or that his audience size can be copied.
What the feed shows
- Nine original posts in 13 weeks, one co-authored creator post and no reposts.
- Four videos, three photo or carousel posts, two link cards and no text-only posts.
- Six of nine original posts published between 8:30 and 11:00 am Central, all on weekdays.
- Thirteen comments on 12 other people's posts, concentrated around teammates, partners, founders and creators.
- Three product and event promotions published on consecutive days were the three weakest posts in the window.
The breakout post
The September 8 selfie video asked a real question, introduced one crisp statistic, reduced the idea to a short thesis — people trust people — named relevant creators and closed with two actions. It linked to the research and asked the audience to share its experience.
Its 7,588 reactions were 11 times the next-best post. The format was more personal than the produced campaign video, and the subject was broader than LinkedIn's own products. That combination is more useful than treating 'video' alone as the explanation.
What an executive team can test
- Open with a question the executive genuinely owns, then earn one sharp insight rather than reciting a data set.
- Use direct-to-camera video when the message benefits from a human delivery; production polish is not the same as relevance.
- Pair event and company posts with real people, scenes and named collaborators rather than defaulting to brand graphics.
- Use comments as a deliberate publishing surface instead of relying on reposts.
- Protect quality by spacing promotional posts and publishing around real moments instead of filling a calendar.
Method and limits
Invisible Keyboard collected public activity from linkedin.com/in/marklobosco while signed in on September 26, 2026. The window covers June 25 through September 25: nine original posts, one co-authored post, zero reposts and 13 comments on other people's posts. Post times came from LinkedIn post IDs and were converted to US Central time.
Engagement counts are snapshots as shown on September 26 and will continue to change. LinkedIn did not show counts for the co-authored post or reactions he gave to other posts. Lobosco also has LinkedIn's distribution and production behind him, so the transferable lesson is the mechanics — not the expected reaction count.
[Questions people ask]
Is this affiliated with LinkedIn or Mark Lobosco?
No. It is an independent Invisible Keyboard study based on public LinkedIn activity.
Can I use the posting times as a schedule?
No. Nine posts are enough to describe his habits, not enough to establish the best time to post.
Can I quote the report?
Yes, with attribution to Invisible Keyboard and a link to this page.
