For Google Adwords you will need to append: ?kw={keyword}&ad={creative}&matchtype={matchtype}&adposition={adposition}&network={network} to your destination URL. Only the parameters which are within the URL will be captured. The kw parameter is required ; tracking will work without the other parameters but the data for these will not be captured or displayed in reports.
Where:
kw={keyword}
ad={creative}
matchtype={matchtype}
adposition={adposition}
network={network}
By appending the above tags to either your Adwords Search keyword or Adwords ad destination URL, you enable Google to push respective values of the click into the curly brackets. This Google provided data becomes part of the visitor’s URL which allows AvidTrak’s JavaScript to retrieve, store and publish the required data.

Example URL:
If your current destination URL is http://domain.com/abc.php
then after tagging your destination URL will appear as
http://domain.com/abc.php?kw={keyword}&ad={creative}&matchtype={matchtype}&adposition={adposition}&network={network}
Remember to turn ON Auto Tagging within your Adwords Account.
Note that the default settings for Bing AdCenter will work with AvidTrak. However, if the defaults have been changed for some reason, please make sure the following tags are there in the Ad Destination URLs: or Bing: ?bk={keyword}
