The key element I learned is to not just say « I was there », « I did that ».
But also to bring something to my network.
This is why my post started with « Yesterday I learned… » and not « Yesterday I represented… ».
Of course including the name of my company in the post has become more complicated (French Payroll Expert by the way).
The other element I learned is « 3/1/1 ».
For 5 posts 1 must be about your job or your company. One must be about yourself, and 3 must bring something to your network.
Basically, you must be selfish 1/5th of your post, honest 1/5th of your post and useful 3/5th of your post. I will give it a try.
