Reddit karma

Reddit karma is the aggregate of upvotes minus downvotes across everything an account has posted, split into post karma from submissions and comment karma from replies. It is the small number next to a username that tells the rest of Reddit, at a glance, how the community has received what that account has contributed over time.

Why it matters

Karma is shorthand for account history and trust. A username with years of comment karma reads as a real participant who has shown up and helped before. A brand-new account with no karma reads as a stranger, and a stranger who arrives to promote something reads as spam almost instantly. The number is not the point. What it stands for is the point: a record of having contributed before asking for anything.

That record is also enforced by machinery, not just by reflex. Many subreddits configure their AutoModerator to gate participation on a minimum karma threshold and a minimum account age, with the floors set per community. A comment or link from an account that falls below those values can be held for review or removed automatically, before a single moderator reads it. Karma, in other words, is partly social proof and partly the credential that clears the automated gate at all.

For operators

Karma is earned by being genuinely useful, not farmed. Answering questions you actually know, helping people with no expectation of return, and contributing to the recurring conversations in a subreddit all build it slowly and durably. Attempts to game it with low-effort posts tend to get spotted and provide no real standing when it counts.

The practical way to think about karma is as the standing you build before a product is ever mentioned. It is what gives a later, rare, in-context mention any weight at all. The deeper version of this argument lives in the cornerstone guide on Reddit marketing for founders, and it sits alongside the broader etiquette covered in reddiquette. Karma is the measurable part of credibility. Reddiquette is the conduct that earns it.
