Prepare child accounts
Prepare source accounts - if you don't have a lead/user list
Child account preparation depends on the strategy, however you will need the basic stuff:
Full Name - come up with a few - it could be anything related to your niche
Username - come up with 5-10: use . and _ as separators, also use some niche words
Profile Picture - for best results avoid photos of people as Instagram may match suspend accounts with similar faces
BIO section - come up with few variations as well, use emojis, etc.
Important: via web automation it's impossible to add the clickable @username or URL into the BIO section.
And it's not recommended for the newly created accounts, as Instagram may suspend them faster.
Photo posts - if needed, prepare different photo posts. The more they are different - the better, as Instagram may match them together
Reels - same with photos: the more, the better; also instagram may match the previews, so it's important to use different previews (randomly chosen frame)
Photo post and reel captions - come up with a few variations of captions, best practive is to use only hashtags: several niche ones and some broader ones.
If you don't have a lead/user list, InstAssist can scrape users for you. The only thing is needed is to research some source accounts (targeting accounts). The recommendations are:
20-100k followers (not too few, not too much - guarantees the best follow back ratio)
frequent posting - at least one post per 3-5 days
for 100 child accounts at least 10-20 source accounts
The list could be plain usernames or URLs.
