What works on LinkedIn
LinkedIn posts can be up to 3,000 characters, but readers see only the first lines before "see more". Those lines decide whether anyone reads on, so open with the problem or a result, not with an announcement. Stories about why you built something, and what you learned, travel further than product descriptions.
For B2B launches
LinkedIn is where many business buyers spend their working day, so it suits B2B products in particular. Name the role the product is for, the result it gets, and ask a question your network can answer. Reply to every comment: early replies help a post reach more people.
Questions
How long can a LinkedIn post be?
3,000 characters. Check yours with the LinkedIn post checker, and make the first lines strong, since that is all most people see.
Should I put the link in the post?
Yes, if you want visits. Tag it with UTM parameters so you can see what LinkedIn visitors did.
When should I post a launch on LinkedIn?
LinkedIn is a workday network, so a weekday morning in your audience's time zone usually suits it.
Is anything I type sent anywhere?
No. The post is written in your browser and nothing is uploaded.
