LinkedIn

LinkedIn is the B2B powerhouse. Organic reach is the best of any mainstream platform (5-15% of followers is normal) and conversion rates from thought-leadership posts are 1-2 orders of magnitude higher than any other channel. Flayr's ideal audience.

• Posts per day
  20 posts (personal profile)
• Caption length
  3,000 characters
• Company Page posts
  100 posts/day

No documented new-account throttle, but brand-new profiles with zero engagement history rarely break 2% reach. LinkedIn's algorithm favours accounts with a posting history — Flayr suggests consistency over velocity.

• Video length
  Up to 10 minutes
• Image size
  100MB per image
• Document size
  100MB PDF carousels

Marketing API: 100 calls/hour/member for personal, 500/hour/page for company. Zernio handles the token rotation so users rarely trip these.

• Links in the main post body are down-ranked. Flayr auto-suggests moving links to the first comment.
• Native video outperforms YouTube embeds by ~3× on average. Flayr warns on YouTube embeds.
• Hashtags cap at 5 before the algorithm starts ignoring them.

  LinkedIn deprecated the legacy /shares v1 endpoint — Zernio migrated to /posts v2 without breakage.

Flayr auto-detects links in post bodies and offers to move them to the first comment (where LinkedIn does not de-rank them). Native video uploads use LinkedIn Video Ad APIs for best reach.
