There’s a metric at the keyword level called Landing Page Experience, which gives an indication of how good the landing page is. It would be useful to pull this data so we can stay on top of it.
you currently provide the options to pull historical Quality Score data (it returns an error most of the time), so being able to retrieve Landing page experience would be great as well.
Also, having Auction Insights available would be helpful to track impressions without needing to log into Google Ads.
