The biggest factors in the LinkedIn Pulse algorithm are traffic and engagement. Pulse will highlight posts have gotten the most views, likes, shares, and comments in the past few minutes.
There are two things you can do to help your LinkedIn posts start trending.
Become Associated With A Channel
LinkedIn Pulse has more than 100 channels for topics including entrepreneurship, leadership and management, productivity, and marketing and advertising. No matter what you write about, you'll find a channel that's right for you.
If you want to help your LinkedIn article become a unicorn, more people need to see it and engage with it. Your personal network is limited, but some of these channels have millions or hundreds of thousands of followers.
So in addition to doing some basic optimization as you write (using the right keywords to help Pulse as it analyzes and categorizes your article), you'll want to tweet to @LinkedinPulse and ask them to feature your post in a specific channel.
Use Social Media Ads
Being featured on a Pulse channel isn't enough to start trending. You also need a catalyst to drive lots of traffic and engagement to your post.
This is where Facebook, Twitter, and LinkedIn promoted posts come in. You can use these ads to quickly drive lots of traffic to your LinkedIn article.
