I have found that it is easier to get recommendations from people on Linkedin if you email them personally and ask. Everybody knows what the canned Linkedin email looks like and they know that you can easily ask all of your Linkedin contacts at once. Linkedin Recommendations are like Yelp Reviews for your resume. Don’t take this script as it is, take it and personalize it to the person you are asking for a recommendation. You should also return the favor.
You can dress this up or down depending on the kind of relationship you have with the person.
Hey Name, I am working on getting a few of the people I have recently worked closely with on projects to write recommendations about me on my Linkedin profile. Your voice and opinion matters to me. I would love to have your thoughts on our work together on my profile for others to see.

Thank you for considering,
