Hi,
Since there is still no way to retrieve Auction Insights info from the API, i found that you can use Data Studio for that purpose.
On Data Studio, when i build a report to retrieve Auction Insight - Domains by Adgroup, I noticed 2 errors on the results:
1- When comparing with the results from regular AdWords (over the same time interval), the Impression Share metric is not similar at all.
2- There are several competitors that show up in the Auction Insight - Domain that have 100% IS. However, when i look up those same competitors in Adwords i see that they show "<10%" IS, so this must probably be a bug on Data Studio side.
Is there any way to solve this? Because Data Studio is very useful to get Auction Insights info in bulk (which is not allowed in AdwordsAPI), however the results are most definitely wrong.
Thanks.
