When starting with a smaller account, it takes some time in the beginning to build up account trust and social proof. If you start from a larger, more established account, you have a head start. People are more likely to trust you and follow you at a higher rate.
If your account has less than 1000 followers, users tend to not follow back as much as they would if you had a larger account. Think about it, would you follow an account with barely any followers? Also, newer accounts with fewer than 1000 followers will typically have a lower Trust Score, so we need to be especially careful when launching your campaign. Also, you need to understand the social proof aspect and know that a certain percentage of followers are likely to unfollow but not all, so over time we can start scaling growth.
We can make progress with any account whether it has 10,000 followers or 300 but our approach and the speed of results will be different.
