SEO for AJAX
From the Search Engine Watch Forums:
"AJAX is kind of like Flash - it looks and acts kind of like a webpage,
but it's actually a program. As such, it's not search-friendly.
Like Flash, there are methods to make parts of it show up, or to
provide alternative content. Also like Flash, much of it's
functionality is based on the operation of scripting (which search
engines don't do) and streaming (which is based on the operation of
scripts).
In short, almost all of the objections to Flash apply to AJAX, even
though they are very different in other ways. Of course, many of the
benefits (engaging, useful, etc) also apply.
Bottom line, you have to plan ahead and provide alternative methods to
show content with AJAX and Flash, or build your site assuming they are
invisible and designing the site to compensate in other ways.
One possible answer to your issue is through the use of CSS activated
via scripting. The content would be hidden until needed, but in the
absence of scripting (which is what a search engine would see), all the
content would be displayed. Test it in a text only browser to see."

The nice thing about AJAX is that a lot of times you have preloaded access to the data and are able to manipulate it on the page in such a way that you can have it there for SE's to crawl through.
