Reddit tracks how much karma each of its users has earned, too. Next to every Reddit post or comment are upvote and downvote buttons. By clicking one of these, you are giving either positive or negative karma to the post. Positive karma increases the number of points a post has, while negative karma decreases that number.
Reddit uses karma as a way of showing the best possible content to users. Upvoted comments and posts with a ton of points end up at the top of the page, which leads to even more people seeing and upvoting them.
Downvoted comments end up at the bottom of the thread. If a post is downvoted enough, it eventually becomes hidden, and you have to click to expand it.
This indicates the post is controversial, which means it has a similar amount of upvotes and downvotes. This karma is divided between post karma, which is the total points of all the threads they posted, and comment karma, which is the total points of the comments they submitted to existing threads.
This is especially true for marketplace subreddits that involve meeting and transacting with people outside of the site. Having a lot of karma across multiple posts makes you appear more trustworthy. Upvoting a post helps other people see it as well. Being an active voter can help improve the Reddit experience for everybody. Downvoting bad posts brings good content to the forefront. While you may be tempted to just post a lot of things in the hope that one of them gets widely upvoted, you should slow down.
In some subreddits, you might be banned for posting too often within the same time period. The best way to get karma is by posting organically. Find subreddits you enjoy reading and become an active member. Contribute to the discussion by sharing relevant posts, joining in on discussions, or making funny jokes.
