Fascinating. What is your plan going forward? Having published over 40 LinkedIn articles some of them very popular and some of them not so popular I could never figure out how the algorithm worked. My headlines were so good that there was no way that my 5000+ connections were not clicking through if they actually had been notified. If you analyze and test my headlines there is not a writer in the world with a higher percentage score than me, yet very little click-through and little engagement as you noted.
Interested to see where this goes!
