LinkedIn® has released content guidance. Remember that this guidance can be considered part of the Terms of Use.
Official LinkedIn® Guidance
We’re committed to maintaining high-quality content on LinkedIn® by being clear about how content recommendations work. To protect our members, some content is not welcome on LinkedIn®. Beyond that, members have surfaced that they’re not interested in certain types of content. This includes content that doesn’t foster a supportive community or risks eroding the professional nature of LinkedIn®, which may not get shared beyond your connections and followers. That’s because these members haven’t chosen to follow you, and content recommended to the broader LinkedIn® community should meet a higher standard for quality and professionalism.
Promotional or Off-topic: Refrain from making posts and comments that are promotional without adding insights or value, as members appreciate relevant content that contributes to the conversation.
Engagement Bait: Steer away from posts that directly ask for engagement, which may attract attention but don’t add value for members.
Unoriginal: Avoid sharing unoriginal posts without added insights.
Content that doesn’t foster a supportive community on LinkedIn
Content that erodes the professional nature of LinkedIn
Unconstructive: Refrain from posts that create negativity and discourage engagement.
Adult and Sensitive: Be mindful of others and avoid sharing adult or unsettling content, as this isn’t the type of content members are looking for on LinkedIn.
