1. CUSTOMIZE YOUR CONNECTION REQUESTS
Instead of using the generic "I'd like to add you to my professional network on LinkedIn" message, tailor each request. Remind him/her where you met or explain why you want to connect. They'll be MUCH more likely to respond.
2. BE RESPONSIVE
Reply within a few days to connection requests, personal messages, or comments on group discussions you post. Stay on top of your LinkedIn inbox! This will keep you top-of-mind with people and opportunities.
3. RESEARCH BEFORE REACHING OUT
Review a person's proﬁle before contacting him/her on LinkedIn. You'll make a stronger connection by highlighting things you have in common or speciﬁc aspects of his/her experience you want to discuss.
4. KEEP IT SHORT AND SWEET...AND ALWAYS PROOFREAD!
In today's busy world, no one wants to read long, dense paragraphs on their computer or smartphone. Keep your proﬁle summary, messages, group discussion postings, and recommendations clear, to the point, and grammatically correct!
5. GIVE MORE THAN YOU TAKE AND ALWAYS SAY THANK YOU
Balance your needs on LinkedIn with those of your connections. In addition to updating your own status and asking for help or connections, try commenting on other people's updates and helping with their requests. Furthermore, when someone answers a question you've posted, provides an introduction, suggests a job, or otherwise helps you on LinkedIn, send him/her a thank you message. The golden rule applies online just as much as it does in person!
