Does Bidbrain hide data (like SMART shopping)

No. Bidbrain is 100% an open book. You will see everything that we do on your Bidbrain campaigns just the same as you would if you were running your own manual Google shopping campaigns. You can access specific detailed reports in the report section of Google Ads, you can see negative keywords that you can use as knowledge for other campaigns, best-performing products, their specific bids and so forth. You will also have access to finished reports in your Bidbrain dashboard and if there is anything you can't find, ask us and we will see what we can do.
