What launched?

You can now better measure the effectiveness your campaign at driving brand awareness with the top-of-search impression share (top of search IS) metric. This metric is defined as the percentage of top-of-search impressions your campaign received out of the total top-of-search impressions it was eligible to serve on. This metric is available for Sponsored Brands and Sponsored Products campaigns with a 90-day lookback window. For Sponsored Products, this metric gives the impression share for top-of-search (first page).

Why is it important?

Use top-of-search impression share to understand how effective your campaign is at driving top-of-search impressions. To help increase the top-of-search impression share for your Sponsored Products campaigns, adjust bids by placement to help improve the chance of serving impressions at the top-of-search.
