Reddit karma
Definition
Reddit karma is the points a user accumulates when their posts and comments receive more upvotes than downvotes. Split into post karma and comment karma, it acts as a rough reputation signal on Reddit. Many subreddits set minimum karma thresholds to gate posting, so karma shapes where and how a marketer can participate.
How it works
Karma is earned when other Redditors upvote your posts and comments and lost when they downvote them. It is tracked in two buckets: post karma (from submissions) and comment karma (from replies). The totals are visible on your profile and give other users a quick sense of whether an account is established or brand new.
Karma is not a one-to-one count of upvotes. Reddit applies dampening and anti-gaming logic, so a post with 1,000 upvotes does not necessarily grant 1,000 karma. The exact formula is deliberately opaque to discourage manipulation, but the principle holds: helpful, well-received contributions raise karma over time.
Karma cannot be bought, transferred, or spent. It is purely a reputation indicator tied to a single account.
Why it matters for Reddit marketing
Many subreddits require a minimum karma level (and account age) before you can post or comment, specifically to keep out spam and throwaway promotional accounts. A new brand account with zero karma will be auto-filtered or removed in exactly the communities marketers most want to reach.
The right approach is to build karma the way any genuine member would: comment helpfully, answer questions in your niche, and share content the community values. This earns standing and teaches you each subreddit's culture and rules before you ever mention your product.
Treat karma as a byproduct of authentic participation, not a target to game. Buying karma or using vote rings violates Reddit's rules and risks bans and shadowbans.
Frequently asked questions
What is the difference between post karma and comment karma?
Post karma comes from upvotes on your submissions (links, text posts, images), while comment karma comes from upvotes on your replies. Reddit shows both separately on your profile. Comment karma is often seen as the stronger signal of genuine community participation because it reflects ongoing conversation.
Can you buy or sell Reddit karma?
No. Karma cannot be transferred between accounts and any service selling karma relies on vote manipulation, which violates Reddit's content policy. Accounts built this way are frequently banned or shadowbanned. The only sustainable way to build karma is genuine contribution.
How much karma do I need to post in most subreddits?
It varies by community. Some subreddits have no requirement, while others ask for anywhere from a handful to several hundred karma plus a minimum account age. Each subreddit lists its rules in the sidebar or wiki, and automod will tell you if your post was removed for not meeting the threshold.
Does karma directly affect how marketing posts rank?
Not directly. Ranking is driven by upvotes, vote velocity, and time on the post itself, not your account karma. But low karma can prevent your post from being allowed at all in gated subreddits, so it indirectly gates your reach.
Upvotes & downvotes
Upvotes and downvotes are Reddit's core voting system. Users upvote content they find valuable and downvote what they find unhelpful or off-topic. The net score drives how visible a post or comment becomes, pushing well-received content up and burying the rest. For marketers, votes are the direct signal of whether a community accepts what you share.
Subreddit
A subreddit is a topic-based community on Reddit, prefixed with "r/" (for example r/marketing). Each subreddit has its own moderators, rules, culture, and audience. Subreddits are where all Reddit discussion happens, so they are the unit marketers must understand to reach the right people without breaking community norms.
Shadowban
A shadowban is a hidden restriction where a Reddit account's posts and comments become invisible to everyone else, while the banned user sees no notice and believes their content is live. It is typically triggered by spammy or rule-breaking behavior. For marketers, a shadowban can silently kill reach, so understanding and avoiding it is essential.
Reddit self-promotion rules
Reddit's self-promotion rules are the sitewide and per-subreddit guidelines that govern how much you can promote your own content. The best-known is the 90/10 guideline — no more than one promotional post for every nine non-promotional contributions. Individual subreddits add their own limits, and breaking these rules leads to removals, bans, and shadowbans.
Reddit algorithm
The Reddit algorithm is the set of ranking rules that decide which posts and comments get surfaced. It combines votes, vote velocity, and time decay across sorts like hot, best, top, and new. Understanding how ranking works helps marketers time and craft content so that genuinely good submissions gain organic momentum.
Reddit marketing
Reddit marketing is the practice of building brand awareness, demand, and trust on Reddit through genuine participation in relevant subreddits. Because Reddit communities strongly punish overt self-promotion, effective Reddit marketing prioritizes value-first contributions, transparency, and respect for each community's rules over direct advertising.
