How to Avoid Duplicated Content
- Put a Copyright Notice on the bottom of your post.
- When you have an article to get republished on other sites send them in a text format. (Articles are a great way to quality incoming links by the way!) This ensures that when the article is republished it will be reformatted and viewed by the search spiders as original.
- If you have multiple domains that point to the same site content take advantage of permanent redirection. (301 status report) This informs the spider of the redirection so they understand you are not putting up duplicate content.
