Here we go … this will help separate the herd once again.  People who neglect to follow will be left in the dust.

Google is implementing display URL changes based on the below blog post (from Google Blog) …

For example, an ad group containing the following group of display URLs would comply with this policy because all URLs contain the same top-level domain, “example.com”:

• www.example.com
• www.widgets.example.com
• www.example.com/widgets/redwidgets/
• www.example.com/index.html

On the other hand, and ad group containing the following group of display URLs would not comply with our policy because their top-level domains don’t match:

• www.example.com
• www.example.widgets.com
