Ads not using the space Google gives them

Ads using fewer headlines and descriptions than Google can combine, for example ten headlines and two descriptions. Usually the reason behind a weak Ad Strength.

The short answer

A responsive search ad can hold 15 headlines and 4 descriptions. Oppy lists the ads that leave many of those slots empty, and counts how many slots are left empty across the account.

Why it matters

Google builds each ad from the headlines and descriptions you give it, testing combinations against each search. Fewer pieces means fewer combinations and less chance of a close match to what someone typed.

Empty slots are also the main reason ads are rated below Good. The Ad strength check reads the rating, which is feedback rather than an auction input. This one says which slots to fill.

How Oppy decides

The check reads every enabled responsive search ad with its headlines and descriptions.

Checks that weigh money or clicks judge what they find on your own account's numbers, not on one figure applied to every account, so what counts as a problem on a small account is not the same on a large one. Checks on settings read how the account is set up.

When there is too little to go on, the check says so instead of guessing. A finding always comes with the rows behind it, so you can read the evidence before you decide.

Check it yourself in Google Ads

  1. In Google Ads, open Campaigns, then Ads, and filter by ad type: Responsive search ad.
  2. Open each ad, or add the Headlines and Descriptions columns where available.
  3. Count the headlines and descriptions in each.
  4. List the ads that leave many slots empty, starting with the ones that spend most.

What to do about it

Fill the slots with genuinely different lines: the offer, the price, a proof point, a guarantee, the location, the keyword itself. Ten variations of the same sentence do not help.

Keep each headline able to stand alone, since Google may show any two or three together in any order.

Anything else? Ask Oppy in the product, or write to the team.

How many headlines should a responsive search ad have?

Up to 15 are allowed. Aim for at least 10 distinct headlines and all 4 descriptions, so Google has enough to combine.

Does adding headlines always raise Ad Strength?

Distinct headlines usually do. Near copies of the same line add little, and Google may still rate the ad Average.
