In the SEO world, there is a lot of strong feelings about what should be indexed and what should not be indexed by Google. SEO is now about removing content, removing links, removing potentially useful stuff from your site. I find it incredibly comical at times that this is where the industry has gone – mostly Google is at fault for this with Panda and Penguin.
