The secret to Instagram's algorithm:Comment engagement
Discover why asking viewers to comment for a guide, plan, or link is one of the strongest ways to turn reach into conversations.
Instagram rewards comments
When you ask viewers to comment for something valuable, you create visible engagement that helps Instagram push your content further.
The traditional problem is manual work
Without automation, someone has to watch comments, send DMs manually, and follow up fast enough not to lose the lead.
CommentKeyword turns that into a system
We detect the keyword, post the public reply, send the DM, and optionally continue the conversation with AI so you never miss momentum.
The viral growth effect
Higher engagement -> more reach -> more views -> more comments -> more opportunities to convert. That feedback loop is why comment-driven CTAs work so well.
