Choosing a keyword that does not fight you

Published 7 September 2026 · 5 min read

Every comment-to-DM campaign starts with a word. Pick a good one and the campaign runs itself. Pick a common one and you will spend the week wondering why the numbers look strange.

Short, sayable, and not a normal word

The keyword has to survive being typed on a phone by someone half paying attention. That rules out anything long, anything with punctuation, and anything people will spell two ways.

It also has to be a word nobody would type by accident. "GUIDE" is fine. "YES" is not, because people say yes in comment threads constantly and every one of them will be treated as a request. The test is simple: would this word appear under your post if you had never mentioned it? If yes, choose another.

Near-misses are the real leak

Matching is generous on purpose, because people type "guide please" and "GUIDE!!" and mean the same thing. The cost of that generosity is that a keyword sitting inside a longer word also matches. "WIN" catches "winner" and "winning". "PLAN" catches "planning" and "planned".

Keyword exclusions are the fix. Add the two or three neighbours you can predict and the noise stops. This takes a minute at setup and is close to impossible to reconstruct later, once your delivered list is already mixed.

Decide which posts it applies to

An automation can watch one specific post, any post on the account, or arm itself for the next post you publish.

Anchoring to a single post is the right default for a campaign with an end. Watching every post suits an evergreen keyword you want to honour whenever someone remembers it. Arming for the next post is for the case where the automation is ready before the content is, which is more common than it sounds and saves editing the campaign after publishing.

If you run two campaigns at once, exclusive post triggers stop them competing over the same comment. Without that, a comment matching both keywords is a race you did not intend to run.

Reuse the same word carefully

Reusing one keyword across months of posts is tempting because the audience learns it. The catch is that a comment can only ever receive one private reply, so someone who used the keyword on your March post and again in September is a different comment each time and will be treated as new. That is usually what you want. It stops being what you want if the two campaigns deliver different things and you cannot tell from your export which one someone came from. Different campaigns, different words.

Say the keyword where people are looking

Put it in the caption, near the front, in capitals. Capitals are not required for matching, but they make the instruction scannable, and a keyword nobody notices performs exactly as badly as a keyword nobody can spell.

Say it out loud in a reel too. A surprising share of comments come from people who never read the caption at all.
