Promote business on Reddit

# Be regular on reddit: Keep posting interesting articles, blog posts etc. on Reddit frequently and regularly. You can also submit your website or your web site's relevant pages on Reddit. Regular submission can also increase your Karma.
# Submit frequently: Ensure that the content you stumble is of high-value for users to spent time on your website. Avoid spamming in groups or forums because it may bring huge traffic in the initial stage but after sometime, it would simply fade out.
# Build your network: Start interacting with other Reddit users. One way of doing this, is by getting involved in discussions that are going on about other people's posts. Try to look for the topics which are similar to yours and get involve by leaving comments. Be careful with your comments, as other users can vote on it. Don't spam by posting your link in the comments.
# Choose the title carefully: Your title plays very important role in getting your submission votes. In Reddit, you do not have an option to write the description. Hence, your title is the only way to attract users and make them click on your post.
# Reply to comment: Reddit allows you to reply to the comment. It follows multi-level threading model i.e. if you want to reply to someone's comment, you can click on the reply button, under that comment and leave your message on that particular comment. It is an excellent way to start a communication but make sure you read the story before you post the comment.
