Instagram DM Automation: The "Comment to Buy" Funnel
Don't put the link in bio. Make them comment "PROFIT" to get the link sent to their DMs instantly. This triggers the algorithm optimization.
Instagram hates external links. If you put a link in your caption, your reach dies. If you tell people to "Link in Bio", you lose 50% of them because it is too much friction.
The ManyChat Trigger
The solution is automation. You post a Reel with a CTA: "Comment 'GUIDE' and I'll send you the PDF instantly."
Step 1: The signal
User comments "GUIDE". This is a high-intent engagement signal. The algorithm sees this and pushes the Reel to more people.
Step 2: The DM
ManyChat instantly sends a DM: "Here is the guide you asked for! [Link]". Open rates on DMs are 90% (vs 20% for email).
This is a CRO tactic for social media. You are converting "Comments" (Vanity Metric) into "DMs" (Traffic Metric).
The Follow-Up
If they don't click the link in 24 hours, the bot sends a nudge: "Did you get a chance to read it? I have a question about page 3." This mimics a human checking in.
