As I already submitted my main domain to social bookmark network, which not allowed to duplicate submit, so I throught if i can use a shorten domain to submit to social bookmark, i tried, it's work, it looks like this http://openbookmarks.info/story.php?id=17171b but i worred if this way will get a published by google, or will this way boost site serp, please give advice, thanks.
Social bookmarking bit.ly type URLs will give you zero SEO benefits. Furthermore: There is no point to submit the same story over and over on Digg (for example). Either submit it to other social bookmarking sites, or publish more new stories than submit them instead.
I don't understand why you would want to submit the same story twice. I agree with poster above. Maybe just create another account and boost it under another profile.
Thanks For your reply, will try if this way is work, i wanted to submit my site with another author text.
Write good article & post it on your website with Share Button. If content is really good people will automatically bookmark article. No need to create multiple account to submit one website.
Sadly unless you have exceptional content or very huge traffic, most of your submissions wont even get an extra vote in most cases
