How successful were you when you used influencer marketing for promoting your business or product?

A few minutes ago, I read an overview of a report that more people take a source of news, not traditional outlets and media, but influencers. [I am attaching the screenshot from Reutersinstitute.]

TL;DR:

FB, YT, IG – More attention is dedicated to news media/journalists

TT, Snap – More attention is dedicated to influencers/creators

X – somewhere between

From my personal experience, we haven’t had much success with famous influencers in promoting the app so that people will download it. However, I think influencers are for awareness/visibility.

Anyway, I am interested in your experiences:

• 1️⃣ Have you used influencer services for your industry? What results did it bring you?

• 2️⃣ Which social networks did you use, and how did you find them? (Specifically, did they contact you themselves, or did you use a dedicated platform for that...)

• 3️⃣ Do you have any good tips on how to build the greatest possible collaboration with influencers?

I would be grateful if you could answer my last question.
