This is a collection of resources put together by Google which teaches you how to optimize your website.

Google has been at the forefront in urging people (mainly web masters, web designers, and web developers) in creating websites which support multiple devices, are fast loading, and standards compliant. With this goal in mind, Google is endeavouring to provide a collection of knowledge articles (tutorials) and videos which help people make their websites load faster thus speeding up the web.

The tutorials span the gamut of CSS, JavaScript, HTTP caching, Web graphics, PHP performance, and of course the new kid on the block HTML 5.

An invaluable resource on optimizing your website straight from the search leader Google itself. Check out the tutorials.
