Google is definitely crawling content in our page that is only referenced within an AJAX request.
I'm wondering if Google is going through the page source, and looking for potentially valid URLs, and testing to see if they've got content.
Here is what our request looks like... which might offer some insight into what's going on.
'$(document).ready(function() {
$("#theDiv").block({ message: 'Getting latest content...' });
$.ajax({
url: '/content/pages/articles?count=4&part=true',
success: function(data) {
$('#theDiv').html(data);
$("#theDiv").unblock();
}
});
});`
