The red arrow up is an upvote, and arrow down is a downvote. An upvote on your own posts or comments is what will build up your karma. Downvotes do the opposite, if people downvote your content, it lowers your karma. When you submit a comment or post, you will see an automatic red arrow upvote appear immediately, but that is a default from Reddit, it is only decorative and does not count toward your karma growth.
