Say if you write an article, why not publish it on your blog or website. This will create more authority status for your website. I've a small doubt here... can we use the ezine articles as the content for squidoo and hubpages? Will it be considered duplicate content?
Squidoo and Hubpages as well as Blogger and Terapad should be part of your marketing strategies for faster indexing and traffic. Pick any niche you want and you'll soon notice that these sites rank the highest in the search engine results due to link popularity..
