Advertisers who check web server logs may find their ads received multiple clicks from a single Internet Protocol (IP) address. This could be a result of:
- A) duplicate keywords added to multiple ad groups in one campaign.
- B) incorrect IP address information filtered from Google Analytics.
- C) Internet Service Providers (ISPs) who assign the same IP address to multiple users.
- D) query parsing being used to show geo-targeted ads to users in a different city.
