For someone who professes an interest in SEO, I feel like I am the last one to get the memo when I discovered earlier today that Google indexes JavaScript. I realized this when checking that Google finally cached DavidRivers.name. I think consensus dictates that JavaScript is ignored, but I imagine that Google prioritizes HTML over JavaScript content.
Apparently this keeps sites a little more honest in quelling black hat SEO attempts of keyword stuffing, and this is certainly something to consider within your overall SEO strategy.
I don’t have anything else to say about this, but I will hopefully enlighten some others!
