On the Google Ads page, open the Segments tab, next to Search Terms. It opens with the campaign that is open or selected, or with the whole account.

It has four views: Device, Time of day, Day of the week, and Landing page. Three cards appear at the top: In the period (cost, conversions, and average CPA), Top performer (the segment with the lowest CPA among those with enough volume), and Spend without conversions (how much, and in which segments). Each row shows cost, clicks, conversions, CPA, and the share of cost and conversions. CPA above or below average is written out, not just shown by color.

You can take action right there:

  • Device: on each row, adjust the bid (or the CPA target) and choose Don't serve or Include again. At the account level, you choose one, several, or all campaigns, and the result comes back campaign by campaign.
  • Time of day and Day of the week: select the rows and click Serve only at these times (or days). The schedule grid opens with the proposal already filled in, so you can review and save.
  • The Audiences for this campaign shortcut opens the connected audiences.

Nothing is saved until you confirm, and you see the before and after first.
