A friend showed me how to multiply the effect of posting on LinkedIn by 100x.
In 2 minutes.

Did you know that you can share your LinkedIn post to all your groups with a click of a button?

Here are the instructions:
1. Post your LinkedIn update or write an article.
2. If you don‘t see your post – Hover your mouse over “Profile” and choose “Your updates”.
3. Hit share near your recently published update.
4. Uncheck “Share an update”.
5. Check “Post to groups”.
6. Type in single alphanumeric keys in the groups section.
For example, when you hit ‘A’, it will show you all of the groups that you belong to starting with ‘A’ – then select relevant groups. Do this all the way down to ‘Z.’
7. Hit “Share”

Done.
Your update has been automatically shared to all the groups.
