The same official blog
announces the beginning of an agreement between Google and Yahoo!
On June 12, 2008, Google announced an advertising agreement that Yahoo! access to AdSense for search and contextual advertising program for their users from the USA and Canada. Additionally, interaction will be developed between the messaging systems of both companies - GTalk and Yahoo! Messenger.
Yahoo! not the only company with which such interaction is planned (advertising and messaging systems).
The official blog separately highlighted the following items:
- This is not a merger . The company only provides access to Yahoo! to their advertising technology by accessing the adsense program.
- This is not eliminating an opponent from the playing field . Yahoo! will continue its business in the field of search and contextual advertising. Yahoo! can use Google technology as little as desired.
- This agreement does not prohibit Yahoo! enter into similar agreements with other companies
- This agreement does not mean that Google will share search traffic. Yahoo! will continue to provide search services through its own search engines and advertising campaigns.
- This does not mean an increase in prices for Google services for advertisers.
