Google, Spiders and AJAX
I was tempted before to write an entire site using a single html page, and update the content using AJAX, almost as a frames system. Components would be updated from backend PHP, and Javascript would be the "HTML" generator as it were - it sounded great in theory, less bandwidth being used as only the parts that needed to change were changed, etc.
Except then I thought about Spiders, and Bots, and how MSN/Yahoo/Google would see the site. As far as I am aware those bots do not have any javascript parsers as part of their makeup - and so, they would essentially see a blank site - which would not be good for SEO.
The alternative then is to redirect them to a lo-fi version of the site - which essentially means making two versions of the site and more hassle and work.
The latter would also require bot identification so that people who can view the AJAX content will get taken to their, and people who cant and bots will get taken to the other part - however this is never easy and it is a bad idea (i thought) to do that based solely on user-agent.
Do you think that the spiders should be parsing ajax/dhtml generated pages now?
