It's 5 months i'm handling a 1700 followers account. In this time i got 5.000 followers and increased the engagement rate to 4-5%. The niche is wedding and before i got the account, it was managed in a very very bad way (no use of hashtags, few hundred of followers bought, same for likes, bad use of captions ecc...). What about the old posts? Shall i delete all the old, low ER stuff? Are low ER posts destroying the quality of the account? What are you usually doing when a client ask to manage his account?
