I agree and disagree with this. And I also think this makes this article healthy. I do not believe that there is no STRATEGY! I work with so many accounts and i have worked out the strategy of growing their accounts and my own accounts with it.
So in my BELIEVE yes there is a strategy. But like in everything strategy is not 1 month or 2 months goal. It is a minimum of 6months investment.
People tend to believe that just opening the account and uploading pictures will bring them success. And i think maybe because of that it looks like EXPERTS don't know what they are talking about. But I believe that there are EXPERTS out there who actually know the steps and strategy. BUT yes, it is not going to happen in 1 month's time.
For example when a client contacts me and has 200–300 followers and says to me that wants 10 k followers after one month. I turn them down immediately. On one hand it is impossible and the second thing is that the person only wants numbers, and this means that they do not want to put the effort into their content. AND HELLO HELLO! Content is the success of your page.
I have very great clients who grow 200–300 and sometimes even 500 followers per week. Just because their content is very good & also we set up the hashtag strategy, when to engage, who NEEDs it and more.
So no, i dont think that no one knows how to grow Instagram or any other channels. THEY DO! But it takes time. :)
