An option on LinkedIn for ordinary (non-paying) account-holders is to upgrade to Premium (paying) status. There are various benefits including "Move your job applications to the top of the recruiter's list." and "Stand out in search results with a premium icon on your profile."
preliminary question
How do things appear to employers when
- they search for potential new employees?
- several job seekers apply via the Apply button?
main question
Assuming employers know the difference between "ordinary" and Premium job seekers, how does that affect their judgement?
I'm not asking about any other possible benefits to the job seeker, such as InMail Messages or Who's Viewed Your Profile.
