Why it is showing 1 impression and 4 clicks in Google Adwords.
Answer is on Google Support Portal :
I'm receiving more clicks than impressions on my keywords or ads
This can happen for three reasons:
- You're looking at reports using the date range "Today." Because impression and click data update at different rates throughout the day, the number of clicks and impressions might not make sense if you compare them against each other.
- Customers are "comparison shopping" by clicking between several ads. Because browsers typically cache search results pages, Google doesn't record multiple impressions, so the clicks can exceed the impressions.
- Customers may be clicking more than one link within your ad. You won’t be charged for more than two clicks per ad impression and Adwords filters out any invalid clicks that we detect.
