Maintaining online relationships is all about consistent engagement and providing value. After you’ve made a connection—whether through a conference, social media, or a project—stay in touch by occasionally reaching out. Share relevant articles, comment on their work, or congratulate them on career milestones. If you’ve collaborated on something, keep them updated on your progress. It’s not about constant communication, but rather meaningful, periodic engagement that keeps you top of mind. Networking is a two-way street, so always look for ways to help or support them as well.
