I apologise for this newbie question but have read the past forum threads looking for an answer and either missed it or am still so new to Google Ads I over-read the answer without understanding it.
I have some KWs that it's common to see the content impressions 10x the search impressions on a consistent basis.
It's also possible if there was recently a news story about your KWs that suddenly content ads jump significently. It's common for us to see a news article on local paper sites that uses AdWords cause us to have a huge temp jump in impressions.
If there is a huge jump in content impressions/clicks then I tend to turn off content ad(s) and have a look in the logs to see where the visitors come from. Based on those facts I will either turn the content ads on or leave them running.
Also, it depends if the content ads are creating a positive ROI or not.
I now know to check local news in a targeted area, thank you very much for that suggestion. One almost has to be a social scientist to put all the marketing necessities into the correct order these days.
