Auto-tagging vs. manual tagging reporting

- Query Match Type (How your keyword was actually matched to the search query)
- Ad Group (The ad group associated with the keyword/creative and click)
- Destination URL (AdWords Destination URL)
- Ad Format (text, display, video)
- Ad Distribution Network (Google Search)
- Placement Domain (the domain on the content network where your ads were displayed)
