01. Hidden text – Create modern CSS based websites with JQuery effects. They often hide large portions of text in layers to display them on click or mouse over for usability reasons. Example: CSS pagination.
02. IP delivery – Offer the proper localized content to those coming from a country specific IP address. Offer the user a choice though. Shopping.com does a great job here.
03. 301 redirects – Redirect outdated pages to the newer versions or your homepage. When moving to a new domain use them of course as well.
04. Throw Away Domains – Create exact match micro sites for short term popular keywords and abandon them when the trend subsides.
05. Cloaking – Hide the heavy Flash animations from Google, show the text-only version optimized for accessibility and findability.
