Bookmarklet(s) for debugging web pages display ads via Google DFP. Note: This ONLY works for DFP Premium; it will not work for DFP Small Business or DART.

A Bookmarklet is a bookmark that executes JavaScript in browser as opposed to navigating to a URL. Bookmarklets should work on all browser on any operating system ( I have not tested phones or tablets ).

Create a new Bookmark (Internet Explorer calls them "Favorites") in your browser and then:

• Name it something meaningful, like DFP Debug Bookmarklet
• In the Location or URL field of your Bookmark, add the appropriate JavaScript code below - it should be on onle line.
• To use the bookmarklet, simply navigate to the web page you want to debug, and click on your bookmarklet.

Highlights all ads called on the page, and provides a full report showing errors and miscellaneous details.

This should be on 1 line, in the Location of your Bookmark. Note: For some reason, Internet Explorer calls Bookmarks Favorites and you need to add the code below to the URL property of your new Favorite.

javascript:void(
  debug_element=document.createElement('script'));
  void(debug_element.src='https://raw.github.com/dlochrie/DFP-Bookmarklets/master/debug.js');
  void(document.body.appendChild(debug_element)
);
