unless, the story is of exceptional nature, no one is going to digg it. people have better things to do than digging everyday articles. once in a while, you can ask your friends to digg your stories, but don't overdo it. too much of manipulation will get noticed.
I just read an article on getting stuff on the first page of digg. Under no circumstances are you supposed to digg your own stuff! Yeah I know then how is your post supposed to get onto digg in the first place? Well hopefully you have alot of readers and one will digg your stuff. Also become friends with at least 100 poeple and participate in digging and commenting on their stuff! Again over 50% of the stuff on the first page of digg comes from the same users. So get one of these guys to digg your stuff somehow! I have given up personally.
You are not writing articles on topics people are interested in reading and the users of Digg are voting for the quality of your content by NOT digging them. It's that simple. Many changes at Digg lately. Might want to come up with a new plan.
If you write content that people are interested in, people will Digg, Stumble, Mixx, or bookmark it where ever. Digg is not the big traffic score you think it is, it's mostly lookers. Even if you get a big Digg, which is hard to come by, especially if you are just promoting your own blog, it won't necessarily equate into money, just traffic stopping by to look.
What headlines did you use when submitting? That's usually a pretty important factor. Take a look at some of the headlines and descriptions of stories on Digg's front page to get an idea of what is successful. I have to agree with hmansfield though. Making the front page will get you a ton of traffic, so much that it will probably crash your server. Unfortunately this traffic is mostly composed of just "lookers" and don't click your ads or anything like that. Not really worth it. I haven't checked Digg in a while but it seems the headlines making it to the front page have actually gotten stupider. "Scary washing machine fetches over $5000," "Man beaten with meat tenderizer," and "PostMan Attacked At House By 6 Months Old Kitten!" are some of the recent popular stories, just to name a few. Unless you write ridiculous content like that, I wouldn't bother submitting. Bottom line is, if you create interesting/viral content, it will spread in other ways. You don't necessarily need Digg as there are a number of other popular social sites out there that can send lots of traffic your way.
Just to add a suggestion...I have gotten many natural link by writing editorials in my niche, not just the news and information. Pick a topic that you have strong feeling about within the niche...point out some inconsistencies and make suggestions for improvement...that sort of thing, and if it is compelling, and you have enough traffic for someone to see it, you will pick up links in other ways...maybe have it posted as topic for discussion on industry forums and quoted on other blogs. Those type of links will bring in targeted traffic, get people to comment and check out your ads and offers...much better than Digg or Stumble traffic. IOW, compelling content that sparks discussion gets links.
Is utter pants when it comes to getting your links out there, you have to be writing about certain things to get some quality traffic from digg, tech and gadget stuff works well, but even so that is highly saturated and stuffed with that type of content on the Digg front page.....try more on your site to provide highly useful content and provide the option of others submitting it to Digg, instead of yourself as it does not work well self submitting your links there....
I have not tried digg just yet. but when I do I suppose I may ask in my private section on my site for my members to digg a specific post and hopefully will see some results from that.
