An important consideration for Google AdWords advertisers is to understand just where their contextual ads might appear. Google notes that AdWords ads can appear on the:
- Google search engine
- Partner search engines (e.g. Aol, Ask.com, Libero / Arianna, Virgilio / Alice)
- Google owned web content sites (e.g. Gmail, Google Groups)
- Third party web content sites (practically any site wishing to display Google ads)
The following slide, extracted from my PPC with AdWords Course, provides a visual overview of where AdWords can appear1.
