Ten days ago I posted about gmail's odd sitelinks. Google had awarded
mail.google.comsitelinks for the search [gmail]. It looked as if it had gone wrong - rather than four useful links we got four links to the same page in different languages.
I noticed today that Gmail has lost its sitelinks.
I've heard some SEM-talkers suggests that sitelinks are purely manual. They're not. They can't be. I'm sure if you looked up a Google Dictionary you'd discover that word manual is defined as evil and wrong. It looks as if there's been some scaling back on the sitelink data refresh due to unsatisfactory results, though.
