Is it possible to integrate Google AdWords or Bing AdCenter data (impressions, clicks, cost) into Adobe Analytics WITHOUT using Media Optimizer?
To integrate Adwords data with Adobe Analytics you might need to use DoubleClick Integration, you can find more details about it here - https://marketing.adobe.com/resources/content/resources/en/exchange/marketplace/apps/doubl eclick-campaign-manager.html
Also, Here is a link to a forum post with some insights given by Ryan - http://help-forums.adobe.com/content/adobeforums/en/analytics-forum/adobe-analytics.topic. html/forum__cjax-hi_all_i_wouldl.html
Let me know if you have further questions. Thanks!

Using Google's value Track parameters, you can capture the data directly into analytics (either via Processing rules or standard analytics data capture)
