Which would do more for a website?

It's a little more complex than that.

EZA is considered a higher authority than Go Articles for a number of reasons. So if you were to create the exact same article, optimizing it for the same keyword in both of them, EZA will more than likely show up on the front page over Go Articles.

They key is actually your keyword phrase. It's not enough to try to rank for a long-tail keyword, you've got to also know how difficult it will be to rank for the keyword.

Go onto SEOChat.com and use their Keyword difficulty tool. If you should be looking for 50% difficulty or lower. 60% or higher could take up to 2 years to rank for. You might have to pick a ton of keywords. Think of your targeted audience.

Once your article is up on EZA, send links to it. Twitter it. RSS it. Facebook it. Obviously, you can have more than one EZA article. Remember, that your articles are kind of like pages on the big website that is called EZA. So the more links you get to your articles, the more links they get, too, further strengthening their page ranking and authority with Google. Win-win situation.

If you have the money, pay for a good SEO company to send links to your articles from good websites. They've got to be from good neighborhoods, not crappy sites. It's gonna cost you. Be prepared to pay around $500 to $700. I had 400 links sent to my Squidoo and it's been getting some daily traffic, but I should have chosen a better keyword phrase to give them to link to. So do your research well.

You may want to try Linx Boss. They'll give one domain (website) 1000 links a month for $127 a month, and you can do up to 5 different domains. Cheaper than most other places and supposedly from very good neighborhood websites. What's cool about their site is that you're linking to one domain, but you can switch out URLs.

In other words, say you want 1000 links a month to EZA and you've got 5 articles. You can rotate those five articles so they get equal link juice time. I want to try them, but I've got to wait until my budget allows.

Building links is still a time consuming process. Don't think you'll get massive traffic in a day or even a few months, but with the more links you've got (permanent, preferably), you'll begin to notice you'll start to have a daily stream of traffic.
