Don’t ask people to ‘mention’ you, or constantly ‘tag’ people, in the hope that they’ll pay attention and share your post. People do this to me all the time and I just find it annoying.
It’s lazy.
It’s fine if there’s only one tag – they’re reviewing your product, for instance – but people often add 20 tags and it comes across as desperate.
If someone comes asking for a ‘shoutout’ it puts me off doing it – even if I might have done it without them asking.
So just stick to sharing the good stuff, and finding clever ways to get people re-gramming your posts (like interviewing them).
