EU Investigates Google’s Manipulation of Search Results- The European Union’s antitrust investigation has begun asking advertisers if Google suggested any relationship between increased paid-search campaigns and improved organic rankings.

- Please explain whether and, if yes, to what extent your advertising spending with Google has ever had an influence on your ranking in Google’s natural search?
- Has Google ever mentioned to you that increasing your advertising spending could improve your ranking in Google’s natural search?
- Is your company aware of the existence of the features in Google’s natural search ranking algorithm which, in your view, might penalize the ranking or display of your vertical search Web site pages?

Google and Facebook announce IPv6 test- Google, Facebook and Yahoo announced this week that they will be performing a 24-hour trial of the Internet Protocol Version 6 on June 8, 2011.
