increase my followers, got any advice

Instead of playing a game on your phone - make a game of following other profiles! .

How I did it: On the app -- Click on a sellers profile, then to who followed that person.

Look for Follow profiles with low # of follows, since they're just likely buyers, not sellers. Or just click follow on all followers that load quickly!

Why? Since Vinted gives a notification of a new follow -- the (few) folks that look to see who followed them = fresh eyes on your closet, independent of a matching search term.

Results: When I play this game, I'll spend 15-20 minutes click-click-clicking as fast as I can. I'll gain 20 to 50 new followers.
I'll gain a new customer every few times I do this. (I also gain new customers when I list a crap-ton of new items --- but this is a marketing tool that can be brainlessly done anywhere, at any time, with minimal effort!).

Hints: Only do this from the app - it's the quickest possible way!! If you only want to see notifications of Likes on your closet items - play the 'unfollow' game. If watching TV, commercial breaks can be productive time!
