The rules
Keep the ranking honest.
1 endorsement is the minimum.
Your $1 registration through your public LinkedIn account creates your first self-endorsement. Your answer to “Why do you choose this skill as your best?” appears with it.
Every additional $1 is one clear vouch.
An endorsement from someone else stays private until you approve it. Only approved endorsements appear publicly and count in the ranking.
Endorse what you know.
Put your dollar behind work you have seen or trust firsthand—not a vague impression of the person.
One endorsement per person.
Your LinkedIn account gets one final $1 endorsement for each person. Choose the category that best represents the work you know.
No additional self-endorsements.
Your LinkedIn-authenticated registration is your one self-endorsement. After that, support must come from another person. Manipulated, fraudulent, refunded, or disputed payments can be removed from the ranking.
A signal, not a certification.
The ranking shows where people were willing to put a dollar behind someone’s work. It is not an independently verified professional credential.
