How to know adwords to adsense converting traffic?

Is it possible to know how well adwords traffic is clicking on adsense through using analytics code?

but how it will specifically report about adwords traffic?

 

You need to tell AdWords to link to your Analytics account, and it will automatically tag all your ad links. You then setup /asclick to be a goal. This will allow you to see which AdWord clicks results in AdSense clicks.

See the AdWords help for more on tagging.

 

to track more accurately urchin code should be added near footer or header?

 

Footer, with astracker immediately underneath it.

 

I have setup everythin right but conversions are not recording at all.
could you please post astracker.js code here so that i can confirm i have right code?

 

Here's what I have (astracker.js exists in root of my domain):

  <script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
  </script>
  <script type="text/javascript">
  _uacct = "UA-******-*";
  urchinTracker();
  </script>

  <script src="/astracker.js" type="text/javascript">
  </script>
