Personally I strategically leave comments on specific people's posts that are part of groups that I value very much.
In this video I show you exactly how to stay top of mind with your network quickly and strategically.
This way you don't have to wonder did I leave a comment on this person's latest post because you can see all of their posts
Step number one is save people to a specific list if you have an organization that has for example eighty members find out who's actually active on Linkedin and create two lists one for all the Members and one for the Members that are actually active.
While you can review all the members maybe once every three months you want to review the people that are active at least once a week
Go ahead and do this for every networking group that you're part of and watch your level of top of mind go through the roof.
What groups are you part of?
