What are some javascript practices I should avoid for good SEO

So I would like to know some things I should avoid doing in javascript for good SEO rankings. In my next site I will use jquery and javascript extensively but do not want to sacrifice SEO. So what do yo开发者_Python百科u think I should avoid doing?

1. Avoid placing content in Javascript (use html/css then manipulate with JS)
2. Use standard links in your html then override their functionality using events

Basically start by building your pages to work without javascript and then add javascript functionality as an additional layer.

jQuery is your friend.
