Over the past year or so I've been changing my own profile using hints picked up from various social media events, blog posts and Tweets. It's surprising how many LinkedIn profiles I've seen that aren't tweaked in the same way, and it seems only fair to share some tips that have been given to me by others. And if you are one of those others, let me take this opportunity to say "thanks".
- Change your public profile URL to help search engines, in particular remove the seemingly random bits on the end.
- Make sure you have relevant headline text as this is the first thing about you that will be presented on search results. A good exercise is to search for yourself on Google, and see what you think of the LinkedIn result. Could it say more?
- Add text descriptions (or "anchor text") to your web site links, don't just say "Company Website" - especially if you have more than one. If you have a blog, remember to add that as well.
One I found is Lauren Fisher's SEO & Social Media Part 4 : Optimising LinkedIn Profiles. These changes don't take long to do, and make your profile look a lot better.
