Google's John Mueller announced on Google+ that he is starting a "working-group" to help JavaScript based sites work well with search and Google. John wrote "how to make JavaScript-based sites work well with search is something I've been getting asked about a bit."
It is because of that, John has started this group over in the Google Groups forums.
John said his "goal is to figure out how things are working out for sites at the moment, what tricks they're doing to "fix" search, and what we need to change or document on our side."
He added that "some sites do crazy things" adding that Google is only able to "see the end result for search, so it's hard to know."
Here are some of the starter threads:
Interesting!
