Zynga, the social game maker, has announced that it will start showing Facebook ads on its website. This is a significant development as Zynga is one of the most popular websites in the world, with over 250 million active users. The move will allow Facebook to reach a wider audience with its ads and could potentially boost its advertising revenue.

Zynga will show Facebook ads on its homepage and in its games, but not in its chat or messaging features. The ads will be targeted to users based on their interests and activities on Zynga.com. For example, a user who plays a lot of farming games might see ads for tractors or fertilizer.

Zynga says that it is working closely with Facebook to ensure that the ads are relevant and engaging for users. The company also says that it will give users the option to opt out of seeing Facebook ads.

Zynga's decision to show Facebook ads is a win-win situation for both companies. Facebook gets to reach a wider audience with its ads, while Zynga gets a new source of revenue. It remains to be seen how effective the ads will be, but it is clear that this is a significant move for both companies.
