Does anyone have any insights on page speed metrics, bid prices and impression share for paid ads?

The use of auction insights can be a good idea to compare the performance of your site with that of other advertisers. When you can view the insights being provided to you by Google, it helps to strategically plan your own bid prices and page speed - planning is in line with your competitors. All these can be viewed by the insight of the same auction that all the advertisers are a part of.
