Find what influencers or big names in your industry are posting on LinkedIn and look at the reactions and comments they’re getting.

Just like on Twitter, people often join into the conversation on LinkedIn and these comments can also be a great source of research for what your audience is looking for/their pain points.

Assess what topics resonate most with audiences (what reactions are long-form posts getting?) and what pros and cons are being brought up in the conversation happening under the post.

Use that data to inform your own keyword research.
