While i’m logged out, my Facebook Profile can not be seen then.
I just wanna let others see me when i give them my link.
All others Facebook Profiles can be viewed without login.
I mean, for example you can see yourself:
https://www.facebook.com/xxxxxxxxxxxxxxx
For my profile, it is showing like:
This content is currently unavailable!
The page you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page.
What privacy tweak should i do?
Go to your Privacy Settings page, then Apps and Websites, then Public Search.
There you can enable Public Search.
