Welcome to the Q&A Forum

Thank you! I'll go for Wordpress.

Not sure, I dont think there's an option for that though. I just go the Photoshop route and remove it from the PDF.

If you want to track an individual lead all the way through the end of the sales funnel and tie it back to the original traffic source to determine ROI, feel free to check out our tool Convertable. It's currently in free beta but we will be launching premium features soon. We created it because there was really no easy way to look up a specific individual lead within Google Analytics and tie it to the end of the sales pipeline. Please let me know if you have any questions or suggestions for how to make it better. Otherwise, you can try manually setting up a similar configuration by extracting data from the Google Analytics cookie and passing it along to your CRM - http://cutroni.com/blog/2009/03/18/updated-integrating-google-analytics-with-a-crm/
