LinkedIn Service Pages are dedicated landing pages that showcase your services and businesses at no cost. Additionally, potential clients can contact providers for free, regardless of connection degree.
The services on a provider’s Service Page will display on the feeds of their network as well as their own.

They’ll also be discoverable in LinkedIn search by members who are and aren’t 1st-degree connections, depending on public profile visibility settings.
Take full advantage of all features of the Services page, including client reviews.
