Google announced they have three new reports for AdWords advertisers to use to help stay on top of their bids and automated bidding.
The new status annotations lets you keep track of your bid strategy statuses by showing you "days left for learning" in your learning status. Google said, "This indicates that the bidding algorithms are still calibrating and how much longer you should wait before making any other changes or evaluating what baseline performance looks like."
If it is set to "Limited (bid limits)" Google will show you what percentage of impressions or spend is limited to help you understand the extent of the performance impact.
The other two reports Google added are (1) Status over time reporting and (2) Target over time reporting. Google explains both:
Status over time reporting maps bid strategy statuses along the bottom of the performance graph. This helps explain what may be influencing bid strategy performance for your chosen date range. For example, if you notice an increase in spend at the same time a bid strategy had a “Limited (not enough data)” status, this may signal that you raised campaign budgets to help drive higher conversion volume and give the algorithms more data to work with to better optimize bids.
Target over time reporting maps your historical targets over performance data to provide better context. For example, a trend line showing a decrease in conversions might initially set off alarm bells. However, if you saw that during that time, you had also decreased your target CPA, that would help explain the performance decline.
