Hi Julie,
Great question about the article writing.
One thing I can add, is that depending on what you are looking for, article writing can help.
Here's an example: my main site (for now)
www.ronscomputerservice.net was getting very little in the way of traffic. Maybe 10-20 visits in August. I wasn't really promoting it.
I wrote a couple of articles dealing with computer problems, backing up, emails, things like that and submitted them to ezinearticles.com. As of today, my site has had almost 400 unique visitors and almost all of that I can track back to the articles that I have written and the link to my site in the resource box is clicked on.
I am readying a site in a different niche and have several articles written already and will be submitting them to ezine articles. The only difference will be that they will be directed to a squeeze page to capture an email address after receiving a free report/ebook.
That goes back to my original question; what are you trying to accomplish by writing articles? If it's driving traffic, depending on the quality of the article, you should have no problems. If it's capturing emails, make sure that you have a quality product that you can give away. If it's redirecting to an affiliate site, I would make sure that it is also a good product.
Hope this helps out.
Ron
