Automated page redirects
The use of automated browser re-directs in any of your pages. Meta Refresh and JavaScript automated re-directs often lead to a Google penalty as the pages using them are perceived to be doorway pages. This technique is especially dangerous if the refresh time is less than 5 seconds. To avoid Google penalties, use a 301 re-direct or Mod Rewrite technique instead of these methods. This involves setting up a .htaccess file on your web server.
