This (Google ads) is one of the reasons why I suggested the ability to "include" pages (not the only reason, but certainly one of them).

The Google ad code varies based on what type of ad you have asked for. A single web page can have multiple kinds and sizes. So, this is what led me to realize that "include" pages would be a great way to tackle it.

Honestly, if the "include" feature were granted in some future release, it would make adding Googles a snap.

Just :

1. Get your code from Google for the desired ad.

2. Paste that code all by itself in a page (file), saved with an .xml extension. Name the file in a way that describes what kind of ad it is (ie. google_wide_leaderboard_ad.xml, or some such)

3. Put an $_include_blah var in the config file, with the the path to the above named file.

4. Drop it in the template pages as needed. Even if you have 5 or 10 or 20 template pages showing the add, you can update the ad's code with a single change to the "included" page.

This would be ideal. And the process could be repeated for each different size and kind of ad needed or desired.
