Using Preview DNS and WordPress Content
Be careful when using WordPress® with Preview DNS enabled on your site.
WordPress uses full URLs to link to your images and posts. If you use Preview DNS to create content, then your WordPress site uses the Preview DNS domain name for your URLs.
Preview DNS URLs are bad for two reasons. First, search engines index the wrong links for your site. Second, when your preview DNS expires, your links will break.
Once you're ready to turn off Preview DNS, you can use the Search and Replace plugin to find all instances of mycooldomain.com.previewdns.com and replace them with mycooldomain.com.
