In the top right corner of your LinkedIn profile, click the down arrow next to the
'Me' button. From the drop-down box, select 'Settings and Privacy.' You'll be redirected to LinkedIn's settings page.
You'll find two options under the 'Visibility' tab: 'visibility of your profile and network' and 'visibility of your LinkedIn activity.'
To update your LinkedIn profile without telling contacts, you'll need to adjust the 'visibility of your LinkedIn activity' settings.
Select 'visibility of your
LinkedIn activity' from the drop-down menu. Then select 'Share profile updates with your network' from the drop-down menu. To reduce the volume, use the toggle button. Your profile updates will no longer alert your connections now that you've removed the service.
