Last May, I wrote about how Google effectively approves of cloaking in the case of content from NPR. The new Google Scholar launch, while good for searchers, leaves the company open to even more hypocrisy over its published policy on cloaking.
My article on Google Scholar touches on this to a limited degree. I've also posted a new article for our Search Engine Watch members that takes a longer look at the issues involved: Google & The Approved Cloaking Problem.
In summary, Google needs to change its cloaking definition to acknowledge that approved cloaking is allowed -- and it definitely needs to move forward with providing better support to ALL web site owners, rather than just some of them.
