Good on you for checking; it’s smart to be sure.
Quick Answer: The definitive check is in the ‘Resources’ section of your profile, where it will say ‘Creator mode: On’. The most obvious public sign is the ‘Follow’ button replacing ‘Connect’ as your main call-to-action.
These changes all work together to re-orient your profile to better showcase the content you create.
First, the most certain way to confirm is to view your own profile and find the ‘Resources’ section, which only you can see. It will state in plain text whether Creator Mode is on or off. Second, look at your profile’s main introduction card; if you see a line of clickable hashtags listing your topics of expertise directly under your headline, the mode is active. Third, observe the layout of your profile itself. Creator Mode moves your ‘Featured’ and ‘Activity’ sections higher up the page to prioritise the content you produce over your work experience. Finally, the change most visible to others is that primary button. If other people see ‘Follow’ as the main option on your profile, you are in Creator Mode.
Cheers,
Jeff.
