Google is crazy good at detecting anything and they are getting better month by month! I would stay away from these. Do your best, exchange a few reviews here, and let the other reviews come organically. If you care about your acc, stay safe.
Well, I don’t think that exchanging reviews is bad, its okay to exchange review because I don’t think that Google bots are going to know that you have exchanged reviews I would say its good way to make sure that your application outfit looks well and good !
If you do it in moderation, it’s OK (exchange a few reviews with fellow devs). But trust me, Google is watching. I know a story I can’t share here, but they busted a much, much more complicated ring of people abusing their system, than simple review exchanges.
Well, that could happen in future but for now it feels like a good trick to take the spotlight over you !
PS: No worries at all I know some people does that and its bad though ! But what can we do we have to survive over the market and that’s the only reason there’s a link otherwise… anyway i always try my best not to make things looks like I am promoting my stuff I believe in giving and taking process :D)
