Comment keyword ideas for Instagram, by niche

By TinkerFeed Editorial. Updated 16 October 2026.

The keyword is the most underrated part of comment-to-DM. A good one gets typed correctly by everyone; a clever one gets misspelled and the DM never fires.

Below are keyword ideas by niche, with the variants to add, and the rules that make them work.

Any comment or a keyword?

If the whole point of the reel is the freebie, trigger on any comment and skip spelling worries. If people also chat in the comments, use a keyword so you do not send a freebie to someone who wrote "so cute".

Several keywords on one reel

A reel can carry two or three rules: RECIPE sends the recipe, LIST sends the shopping list, CODE sends a discount. Keep it to three at most, or people will not remember which to type.

Check after the first hour

  1. Open the comments and look for requests your rule missed.
  2. Add those spellings as variants.
  3. Reply personally to anyone who asked a different question.

How many variants to add

Start with five or six common spellings of each keyword, then add whatever you see in the first hour's comments. After a few reels you will have a list that covers almost everyone, and you can reuse it.

Say it, show it, pin it

Frequently asked questions

What is a good comment keyword for Instagram?

A short, obvious word that matches the freebie, like RECIPE, NOTES or LINK, said in the video.

Should I add misspellings as keywords?

Yes. Add the variants people actually type, including Hinglish ones, or trigger on any comment.

Can one reel have more than one keyword?

Yes, if your tool supports several rules per post. Keep it to three at most.

Do Hindi-script keywords work?

They can, if your tool matches them. Many Indian audiences type in Roman script, so add both if your followers use both.

Should keywords be in capitals?

Writing them in capitals in the reel makes them stand out, but set your rule to match any capitalisation, since people type them in lower case too.

Why are some comments not getting my DM?

Usually a spelling your rule does not include. Check the comments and add the variant.
