Do I need to submit lots of articles to ezinearticles, if the url on the resource box of all the articles is the one and the same? Or is it enough that I only submit one article per one unique blog url on the resource box to earn backlink?
If you write keywords rich article minimum number of articles is better but at least more than three.
It is good to have alot of articles on ezine, but they are not the only article site you should also be submitting to>> http://www.goarticles.com/ http://www.articlealley.com/ http://www.articlesbase.com/submit-articles.php << anyway all these sites have good PR.
eza lets u submit upto 10 to begin with after which your account goes under review. based on the review, you either get promoted to basic plus form basic, or directly to platimum. basic plus allows you another 25 submission after which your account goes under review again to see if you qualify for platinum. once you get the platinum status, you can submit unlimitted articles. regarding resource box, you can use different resource box for different artciels but can have upto 5 resource box saved per author.
I submit only one article per month to the big ones. It's not easy to write an article that will be accepted by these article directories.
You can usually customize your resource box for each article. You should also consider using multiple directories besides ezinearticles. And finally you can really have too many articles in my opinion.
I guess you can submit at most 3 articles in a day. Some sites don't allow so many. Maybe at most 2 links will do. Once people get interested of your article, they would want to know more about the author, then you get a backlink.
I don't think there is one right answer to how many articles you should put on Ezine. I would just say from an SEO and traffic standpoint to not spend a lot of time on it as it is not a magical answer to anything but you should be submitting about 5 articles a month to see an impact. After awhile you will have it built up enough to see consistent traffic coming in for your website and you will get a small SEO boost.
I agree. There is no magic formula on articles, or link building. (Let me rephrase that...there is, but only Google knows what it is), I see some people claim they submit 20 articles a day and up, and others say 10 total and they submit the same articles to all the directories. It depends on more than just how many...there is also the competition in the niche to consider, and the repetitiveness of the information that you are providing. Even rewritten articles are redundant to readers, although they might mathematically fool the SE's....for now. The only thing I can say for certain is one article will not do much good, unless it is an untapped market, and submitting articles in high competition niches like Acai Berry is also a waste of time because every thing has already been said in multiple ways, with every variation of headline there is, and there have been no new developments in the product. You should always have a balanced attack, but there is no hard fast rule that says:"If you submit 50 articles here, and 100 articles here, with 70 comment links, and submit to 2000 directories, then you will get a certain PR and this much traffic". There cannot be because competition in each niche is unique.
