Instagram doesn't let you post clickable links in feed captions or comments. The only native options are bio links and Story link stickers. But there's a better way: automatically send links via DM when followers engage with your content. It's faster, more personal, and converts significantly better.
Three Ways to Auto-Send Links via DM
1. Comment Keyword Triggers
The most popular method. Add a CTA to your caption like 'Comment LINK to get the free template!' When someone comments that keyword, they automatically receive a DM with your link. Works on feed posts, Reels, and carousels.
2. Story Mention Auto-Replies
When someone mentions your account in their Story, PostLink can auto-reply with a thank-you message and a link. Great for building relationships and rewarding people who share your content organically.
3. DM Keyword Responses
If someone sends you a DM containing a specific keyword, PostLink replies automatically. Useful for handling common requests: 'Send me PRICING for our rate card' or 'DM us MENU for this week's specials.'
PostLink automatically wraps your URLs in trackable links. You'll see exactly how many people clicked, when they clicked, and which keyword drove the most traffic — all in your dashboard.
Step-by-Step Setup
- Create a PostLink account and connect your Instagram
- Go to Automations → New Automation
- Select your trigger type (comment, Story mention, or DM)
- Enter your keyword and paste your destination URL
- Write a friendly DM message — keep it under 300 characters
- Test the automation by commenting/messaging from another account
- Add the keyword CTA to your next post or Story
What Makes a Great Auto-DM?
The best automated DMs feel personal, not robotic. Use the recipient's name (PostLink supports this), keep the tone conversational, include exactly one link, and end with an open-ended invitation to reply. This keeps the conversation going and signals engagement to Instagram's algorithm.
- Start with a friendly greeting using their name
- Acknowledge what they commented or asked for
- Deliver the link prominently
- Add a brief description of what the link leads to
- Invite them to reply if they have questions
