Google Penalty World

Here's an excellent visual poster illustrating the key differences between the type of SEO activities that were effectve back in the days before Google Panda and Google Penguin made their first appearances, and the ones that are appropriate and effective today.

Things have changed a lot in these last two years, and this visual diagram does a great job of reviewing and synthesizing what has really changed.

Whether you are new to web publishing or have a long established web presence, I think you will find lots of valuable information in here as well as many confirmations of things you thought but weren't sure of when it comes to SEO.

Up-to-date. Factual. Informative. Must-read. 8/10
