My reports include sites I don't manage

There are many reasons for why our systems might attribute a few impressions to sites that you do not control and that do not directly have your ad tag on them.

Common reasons

• Sites that serve the contents of your site from their own domain
  For example, Google cached search results and Google Translate may retrieve your content, then serve it from a Google domain, without iframes (in this case the content is shown through webcache.googleusercontent.com and translate.googleusercontent.com).
• Improper iframed redirects
  For example, some sites create an iframe through which they reference another site.
• Web pages forwarded in email clients
• Duplicate content hosted by multiple publishers
  Copy and pasting, or otherwise duplicating, stories from one publisher to another can cause this issue.
