I recently started focusing my SEO by doing article submission. It seems to have helped with backlinks and rankings. What are your opinions of article submission? How often do you need to do it? Should you be submitting articles to many directories?
How do you check for supplemental index? Now I am worried that my article submission is going to hurt my rankings. I didn't realize it can be such a bad thing. John, is there a way to check my website to see if this is going to cause a problem?
