I am researching reasons why Adwords conversion numbers don't match up with the actual number of orders on my website. I only have 1 adwords conversion tracking pixel and it's only placed on the order confirmation page. Google says I have X sales/conversions in the last week and our own internal tracking is quite a bit lower. I've confirmed that no customer have canceled orders. What other reasons have you seen that could cause Adwords conversion totals to be HIGHER than the actual number. Appreciate the assistance.
