For me, my attempts to engage an audience is really important, especially as a new author, but what I am realizing that I need to looks past this "fools gold" and see what benefit that I'm receiving from my increase in engagement. In other words, am I driving traffic to my website? Am I receiving more feedback? Getting more interest in cross-promotion with other authors and providers? Am I getting more downloads of my work?
I suppose that what I'm trying to say in a "not too brief manner" is that it's not just the increase in the number of impressions that matters. It's not just the % increase of followers from month to month but looking deeper into my social media presence and really figuring out what my objectives are, and if my strategies are also helping me reach them.
To an extent, maybe there's a distinction in long term and short term social media marketing and strategization and that it is a good thing to have that increase in analystics. I'm a software guy, and now I'm an author, but I certainly am learning on the fly about all of this social media stuff, so the learning continues!
