Submit a link or content that is different. If you have an article that you want to share but three or four other users have already shared similar content, it's unlikely that your article will get bumped to the top -- especially if your overall link quality is inferior to those already posted.
Websites like Reddit are meant to help users discover funny and interesting content. Typically, users vote for good articles, moving them higher up in the list of available articles for perusal. Getting your post featured on the top of Reddit often means an increase in hits to your website or blog. Unfortunately, not just any content makes the cut. By submitting a link that contains the right type of media and the Reddit-approved tone, you have a better chance of getting your post to the top of Reddit and enjoying self-promotion and/or a little online fame.
Add your submission to the subcategories as well as the front page for Reddit. Most users want the most exposure, so they only submit to the homepage. The subcategories at the top of the page have fewer submissions, which means less competition for you and a better chance at getting to the top and staying there longer, for more exposure.
Create an engaging headline for your post. The right headline encourages users to click your link, which helps push your post to the top of Reddit. Engaging headlines include those that are related to celebrities or current events and mysterious titles that entice users to click to see an answer, such as "Look what I caught my roommate doing!"
Post content that typically gets plenty of interest on Reddit. Some of the most popular content includes celebrity posts, political funnies, Internet and technology news, and bizarre information and tips. The more appealing your post is to the masses, the more likely you'll get to the top of Reddit and stay there.
Include media with your post. Text posts don't always do as well as posts that have an attached picture or video. Not only does media add interest, but it also posts a thumbnail next to your your submissions to help generate clicks and interest.
