50 Comment-to-DM Keyword Ideas That Get People Commenting (2026)

The keyword is the smallest part of a comment-to-DM setup and the easiest to get wrong. Pick a word people type by accident and your automation fires on comments that were never meant for it. Pick a vague one and people don't know what to type. So here are 50 keyword ideas sorted by campaign type, plus the four rules that make a keyword work.

Start with the rules, because they decide whether any of these will fire cleanly.

The four rules for a comment-to-DM keyword

1. Short and single-word. One word beats a phrase. People remember LINK, not "send me the link please."
2. Not something people type by accident. Never use the, love, nice, yes on a post where "yes" is a natural reply. If the keyword shows up in normal conversation, you'll misfire.
3. Obvious from the offer. RECIPE for a recipe, PRICE for a price list. The keyword should telegraph what they get.
4. Say it in the caption, exactly. Whatever word you set, put that exact word in your caption. "Comment GUIDE," not "comment below." The number one reason automations don't fire is people commenting the wrong word.

One more thing: if your audience comments in Hindi or Hinglish, pick a keyword that survives Roman script (LINK, GUIDE work across languages), or use a tool that matches across languages. heyy.to handles Hindi and Marathi keyword matching for exactly this.

How to choose from this list

Match the keyword to the single most obvious word for your offer, then sanity-check it against rule 2. For example:

• Selling a paid course? ENROLL or WAITLIST beats a generic LINK.
• Running a giveaway? ENTER or WIN is clearer than YES.
• Dropping a discount? SAVE or CODE tells people exactly what they'll get.

The clearer the keyword-to-offer match, the more people comment, because they know what they're getting before they type.

A word on "any comment" mode

Some campaigns skip keywords and DM everyone who comments anything. That's fine for a giveaway where any comment is an entry. It's risky for a normal post, because you'll DM people who just said "love this reel" and didn't want a link. Use keywords for most campaigns; save "any comment" for contests where every comment genuinely is an entry.

Keywords that misfire (avoid these)

• Common words: the, a, love, nice, cool, wow. They appear in normal comments constantly.
• Emoji-only triggers: hard to type reliably, easy to miss.
• Long phrases: "send me the link" is more to type and more to get wrong. One word wins.
• Anything in your niche's normal vocabulary: a fitness account using GYM as a keyword will misfire on every comment mentioning the gym.

FAQ

What's the best keyword for comment-to-DM? The one that most obviously matches your offer and isn't a word people type by accident. LINK, GUIDE, PRICE, RECIPE, and BOOK are reliable defaults.

Can I use more than one keyword per post? Many tools let you set several keywords for one automation, so LINK, LINKS, and SEND all trigger the same DM. That catches variations people naturally type.

Should the keyword be uppercase? Uppercase in your caption makes the ask clear, but matching is usually case-insensitive, so someone typing "link" still triggers it. Write it uppercase to signal it's the magic word.

Why isn't my keyword firing? Usually because people are commenting a different word than the one you set, or your keyword is too close to normal comments. Match the caption to the keyword exactly. More fixes in Instagram auto-reply not working.
