A large proportion of the Reddit crowd is fazed and has seen just about everything done on the Web.
So the best case scenario is that your content is unique and refreshing. To make more out of your average or not so unique material, the following pointers will at least give you an edge over competing submissions.

Reddit visitors can vote up or down for your submissions. Downvotes can also be of advantage as this gives your submission extra exposure in the Most Controversial sections. This again gives you extra views and clicks.
Get a Discussion Going
This can tie in with point 1 of being controversial. Getting a discussion going in the comment section of your submission helps to gain more exposure and votes, often generating multiple return visits to your link.
Put some Thought into your Link Title
Short and snappy or long and detailed? Every type of submission fairs better with different styles of link title. I have found that single page picture or video submissions do better with a short maybe 2-word title than a long descriptive sentence.
The opposite goes for text submissions. This again is my own experience so you should closely monitor your submissions and the style of titles used to judge for yourself and emulate the best content/title style matches.
Monitor the Time of your Submission
While monitoring your submission you should also take note of the time. Traffic amount and type on Reddit differ greatly during the day and also week.
Factors such as office hours and habits of your target demographic play into the best time to post on Reddit. e.g. Will your link be of interest to the guy at work, the stay at home mum or the (maybe) drunk college student at 2 in the morning?
Map out your submissions and note all important factors that play in. After a while, you will have a good idea of content type/time of day results.
If you do not see the desired results fast enough, don’t be tempted to register endless amounts of accounts to vote for yourself.
It is better to have one solid account with a good reputation that actually pulls some weight when submitting.
