I have been writting a lot of uniques tech articles for http://thetechpost.com ... (not yet published, still working on a lot of them) but I was wonderng how I can expose these unique articles and gain hits to my sites?
Use digg, fark, furl, yahoo, slashdot, etc. to post your articles. Submit articles to article submission sites, etc. You can gain a lot of visitors by doing so. Creating unique content will create visitors and comeback visitors as well. Good luck.
If you do submit your site to article directories its a good idea to submit a summary article for the main article taht will be on your site. This enables your site to keep all your unique articles instead of them just spreading around other sites.
I've seen some guys using PRweb.com for articles. I'm not sure if it works, but hey, they're free, so why not try?
