Younger members use LinkedIn mostly for job searching and networking, while more experienced professionals use it to demonstrate expertise, promote businesses, and win new business. Setting up a company profile enhances your brand presence beyond a personal profile. Joining groups in your target market and getting involved by commenting, answering questions, and surveys helps you stay active and build credibility through recommendations. Regular but moderate engagement of 1-2 hours per week through status updates, questions, and groups is enough to stay top of mind without overcommitting time.
