You just created a Reddit account for your brand. You try to post in r/SaaS or r/Entrepreneur and... nothing happens. Your post gets removed because you don't have enough karma.
Karma is Reddit's reputation system. Many subreddits require a minimum karma score before you can post or comment. This is designed to keep out spammers, but it's frustrating when you're a legitimate person trying to contribute.
Here's how to build karma quickly without gaming the system.
What karma actually is
Karma comes in two types: post karma (from creating posts) and comment karma (from commenting on posts). You earn karma when other users upvote your content. You lose it when they downvote.
Most subreddits that have karma requirements care about comment karma specifically. They want to see that you've participated in discussions, not just posted links.
There's no official number that works everywhere. Some subreddits require 50 karma, others require 500. The requirements are usually listed in the subreddit rules or wiki.
The fastest legitimate way to build karma
Comment on rising posts. Go to popular subreddits in your niche and sort by "rising" or "hot." These are posts that are gaining traction but aren't yet on the front page. Early, thoughtful comments on rising posts get more visibility and upvotes than comments buried in a thread with 500 replies.
Answer questions in your area of expertise. Subreddits like r/AskReddit, r/NoStupidQuestions, and niche Q&A communities are karma goldmines. Find questions you can genuinely answer well. A single detailed, helpful answer can earn hundreds of karma.
Share useful resources. If you know of a great free tool, guide, or resource that a community would appreciate, share it. Just make sure it's not your own product (not yet, at least). Redditors upvote people who share genuinely helpful stuff.
Be early to trending topics. When news breaks in your industry, get to the relevant subreddit quickly and share your perspective. Being one of the first informed commenters on a trending post is one of the fastest ways to earn karma.
What not to do
Don't use karma farming subreddits. Places like r/FreeKarma4U exist, but using them is obvious and many subreddits will ban accounts that have most of their karma from these communities.
Don't repost popular content. Copying someone else's viral post and reposting it might get you karma, but it also marks your account as a low-effort reposter. Moderators check for this.
Don't spam comments. Posting "this!" or "great post" on dozens of threads won't help. Short, low-effort comments get downvoted or ignored.
Don't buy karma or accounts. Reddit actively detects purchased accounts and bans them. It's not worth the risk.
A realistic timeline
If you spend 15 to 20 minutes a day commenting thoughtfully in relevant subreddits, you can reach 100 comment karma in about a week. That's enough for most subreddit requirements.
To reach 500 or more, plan for two to three weeks of consistent activity. Focus on quality over quantity. One great comment that gets 50 upvotes is worth more than 50 mediocre comments that get 1 upvote each.
Using your karma wisely
Once you've hit the karma thresholds you need, don't suddenly switch to full self-promotion mode. Reddit users and moderators notice when an account goes from helpful community member to nonstop marketer.
Keep the ratio healthy: for every comment mentioning your product, make at least 9 that are purely helpful. This keeps your account in good standing and builds the kind of reputation that actually drives results.
Tools like RedShip help you find the right conversations to join by monitoring keywords in your niche. Instead of browsing Reddit aimlessly hoping to find relevant threads, you get alerts for conversations where your expertise is actually needed. This makes your karma-building time much more efficient because you're commenting where it matters.
The bottom line
Building karma takes a little patience, but it's not complicated. Be helpful, be early, and be genuine. The karma will follow, and so will the credibility that makes your future marketing efforts on Reddit actually work.
