Dealsdirect.com.au was reported this week as being hacked and blocked by Google. Today I show you a couple of simple things you can do to minimise the chances of this sort of attack and if your site does get hit, how you can revive your rankings. Google has temporarily redirected Google.cn to it's Hong Kong counterpart as it continues it's opposition to China's censoring of the Internet. It has also attacked Australia's proposed Internet filter. Do you have PDFs on your site? Whitepapers perhaps? A great question from a viewer reminded me how they could be used as backlink "trojans". Also we look at best practice of HTML vs PDF for Google.
