I have a page I grew from 0 to approx 7K in a month its called 500Hugs. I got lazy and didn’t post for a while. Niche was not clear too. I used to post random stuffs that I like. I remember 1–3 post that Iposted got a good reach and after nearly over a year of that I’m posting it again. But the followers are decreasing in number. The followers are decreasing rapidly and down to approx 4k.
From my experience i can say that the main thing you have to do is post quality content consistently and never abandon you followers like me. Hope someone can learn from my mistakes.
