Cross-posting is killing your reach

Writing one post and copy-pasting it to four platforms feels efficient. It isn't. A LinkedIn post written as a 1,200-character story dies on X as a wall of text nobody scrolls past. An X-style hot take that does 50K views looks thin on LinkedIn. Same idea, wrong shape, wrong result.

Repurposing is different. Same idea, native shape for each platform's length and tone. Same effort, three to ten times the reach. That's what this tool helps with.

The rules each platform actually cares about

LinkedIn

3,000 character hard limit. Sweet spot is 1,000-2,000 characters. The post truncates at about 1,300 characters with a "see more" prompt, so make the first 1,300 stand alone. Outbound links suppress reach. Put them in the first comment. Three to five niche hashtags. Conversational, story-driven, first-person.

X (Twitter)

280 characters per tweet. Every URL counts as 23 characters regardless of length. Hashtags above two read as spam. Lists, short lines, and confident opinions outperform walls of text. Threads work but each tweet has to stand alone in case people only see one.

Bluesky

300 characters per post. Audience skews thoughtful and tech-leaning. Threads work better than single posts at the upper end of the limit. No t.co-style URL shortening, so long links eat real characters.

Threads

500 characters per post. Tone is closer to early Twitter than to LinkedIn. Casual, energetic, slightly longer than X. @ mentions don't behave the way they do on X, so cross-pasted mentions often go nowhere.

FAQ

Why does X count links as 23 characters?

X shortens every URL to a t.co link of fixed length. No matter how long the original is, it counts as 23 characters against the 280 limit. This tool counts links the same way X does.

How many hashtags should I use on LinkedIn?

Three to five is the sweet spot. More than five and LinkedIn's algorithm starts reading the post as spam. Specific niche hashtags beat broad popular ones every time.

Should outbound links go in the LinkedIn post body?

No. LinkedIn deprioritizes posts that send readers off-platform, so a link in the body suppresses reach. Put the link in the first comment and add a "link in comments" note to the post.

What's the difference between cross-posting and repurposing?

Cross-posting means writing one post and pasting it everywhere. Repurposing means writing the idea once and shaping it natively for each platform. Repurposing performs 3-10x better because each platform's audience expects its own shape.
