Ho do I extract from Adwords competitors data, impr share and avg pos.
Thanks for your question.
You can only fetch your own account's data from AdWords API with Supermetrics, sorry.
Understood what you're looking.
In Supermetrics sidebar, Select metrics panel you can find a whole section named IMPRESSION SHARE. Also Average position is available under BASIC section. Please find the metrics you're looking for there.

Is it possible to get "Display URL domain" and associated data from Auction Insights?
