Beautify your LinkedIn profile link
Two unsolicited advice for LinkedIn users:
Beautify your LinkedIn profile link
Check your the URL of your LinkedIn profile It might be something like this: https://www.linkedin.com/in/foo-bar-b5b37626/ You can change that to some nicer address. For example: https://www.linkedin.com/in/foo-bar/ or https://www.linkedin.com/in/foobar/
See this answer for more details.
Remove duplicate profiles
Anoth issue that I see here and there is that some people have multiple profiles created when they were invited via different e-mail addresses. I know this happened to me a long time ago.
If you have multiple profiles you can merge them.
