Jane uses AdWords to promote her online shoe sore and her
conversion rate has remained constant over the last year. While checking her
web server logs for December, she notices she sometimes gets two clicks from
the same IP address within a few minutes. The most likely cause of this is:
A) inaccurate web server log information
B) automated software designed to click on her ads
C) users who are comparison shopping for shoes
D) users who click on an ad on the Google Display Network
