Often, I will recommend article submission as a way for my clients to send traffic to their web site. A couple of well written articles can provide you with great backlinks and some traffic directly from the article site. The basic premise behind this is that someone who wants the content that you have written will copy it, leaving the link to your site intact (per the terms of the site you submitted your article to). This places your link on other sites of like content, which is helpful in the Search Engine Optimization process. This is a win/win situation for both sites…you get backlinks, and they get content.
Several sites that provide submission services are available and they are usually free. I like ezinearticles.com – they seem to be the highest quality, and all articles are human reviewed before releasing them to be read by the public.
Don’t forget that you should re-write the article if you are submitting to more than one service, or taking it from your blog.
