This module adds tracking information (JS) to nodes that you want to track for
advanced ROI reports with Google Adwords

REQUIREMENTS
------------
* Google Adwords Account
* An existing conversion tracking in your Google Adwords account (you will
  need the information from this to complete setup)

INSTALLATION INSTRUCTIONS
-------------------------
1.  Copy the files included in the tarball into a directory named
    "google_adwords" in your Drupal sites/all/modules/ directory. (Or use
    drush "drush dl google_adwords")
2.  Login as site administrator.
3.  Enable the Google Adwords module on the Administer -> Modules page
    (Under the "Statistics" category).
4.  Fill in required and desired settings on the Administer -> Configuration ->
    System -> Google Adwords page.
5.  To complete the installation you will now have to add the Google Adwords
    field to a content type.  Under Structure -> Content Types ->
    <Choose Your Content Type> -> Manage Fields -> Add new field
    (Field type: Google Adwords).
6.  If you have setup all the information in #4 with your Google Adwords
    tracking information you will now see the information from step 4 as the
    default value for the field. Save content type.
7.  One last step before tracking will function. Conversion labels have to be
    setup on a per node basis!
    Now edit a node that you want to track.  Find the Google Adwords field and
    supply the "Conversion label" that Google Adwords gave you when you setup
    tracking look for "var google_conversion_label = "SOMELONGSTRINGOFSTUFF";"
8.  Enjoy better ROI tracking on your PPC campaigns.
