I did all the tests here
Look if you are into article marketing most people would say that ezine articles is the best,this is absolutely false!
Most people think that since it has got a high pr and authority ,the articles would end up on the first page.Guess what you are absolutely wrong.
I mean cmon!,it takes a week to get approved(unless you are a platinum member),and they dont even give a platinum status that easily.I have around 75 articles and still I am a basic plus(My articles are of high quality and every time I apply for platinum they just reject me,I suspect it is because I write articles on different niches)
I absolutely got frustrated last month,and decided to give up eza.I then tried out goarticles.
I found out that goarticles rank better on serps than ezinearticles and they get approved very quickly.
This is what happened,i decided to write an article on a mid competitive keyword(its a secret) and post them to eza and goarticles(articles were different but are based around that keyword)
Result:Goarticles ranking on second page without any backlinks and guess what ,eza ranking on page 9(also with no backlinks)
So what does this suggest:Goarticles is much better than eza if you are into article marketing.If you think I got lucky,then you are wrong.Tested it five times and goarticles beats them all!
One thing to note here is that if you are into backlinks then i found out that 5 backlinks from eza are equal to 20 backlinks from goarticles.
So this means that eza gives more link juice to your site than goarticles.
Bottom line is:Use goarticles if you want your articles to rank highly on serps and use eza for building backlinks.
By the way I made $850 last month just by using goarticles
What do you think of EZA?
