It's not enough to state what you did — what did you achieve?
Talk about your achievements, rather than listing the things you do.
Very often, when employers advertise job, they sensibly include a list of the responsibilities the person they are hiring will have.
That's great when you are hiring, but completely uninspiring when listed on a profile.
Including this same list on your LinkedIn Profile makes you look like an uninspired box-ticker.
"Here is a list of the things that I do. All of them."
Yawn!
Make a list of your achievements in your current, and past roles.
If you can include hard numbers and outcomes that have benefited your employer or your customers, all the better.
You should focus on what positive outcomes have resulted from your work for your employer, for your clients, or for both.
