A source at the company, a Google Search Quality Engineer, who couldn't be named for privacy reasons, had this to say:
"Google take privacy very seriously. After our very successful hiding of organic keywords, people reached out to tell us how important this is to their daily lives. Now, they don't need to be embarrassed about using Google to search for drugs, weapons and ideas for criminal mayhem. As such, all organic results will be shown as "(not provided)" and the links will be disabled. Naturally, Paid-ads will still show, as people are paying for that, so it would be kind of wrong not to" -- (Not Provided)
Google Chairman, Chris Muller-Lite said that the company were just trialling the idea and that (not provided) would only make up a tiny share of the organic search results and most people wouldn't even notice.
It really is a bit of a complete joke!
