Ad group

A set of keywords and the ads that answer them, inside a campaign. Keywords in one ad group should share one meaning, so one ad can answer all of them well.

Why it matters

The ad group is where a search meets an ad. If its keywords mean different things, one ad cannot answer them all well, and click-through rate, Quality Score and conversion rate all suffer.

It is also the level where you compare ads, set some bids and choose the landing page, so a clear ad group makes the rest of the account easier to manage.

Where to find it in Google Ads

  1. Open Campaigns, then a campaign, then Ad groups.
  2. Open an ad group to see its keywords, ads and settings.
  3. Check the Ads tab to see how many ads are enabled in it.
  4. Use the keywords report filtered by ad group to see what it actually matched.

An example

A florist splits a campaign into two ad groups: wedding flowers and funeral flowers. Each has its own keywords and an ad that speaks to that occasion, pointing to the right page, instead of one ad trying to cover both.

Common mistakes

  • Mixing keywords with different meanings in one ad group, so no ad fits them all.
  • Running a single ad, so pausing it takes the group off air.
  • Counting ad groups by name: copied campaigns reuse names, so check by ID.

Checks that look at it

  • Campaign: The level of a Google Ads account that holds the budget, the bid strategy, the networks, the locations and the languages.
  • Keyword: A word or phrase you bid on, with a match type that decides how closely a search must match it.
  • Responsive search ad: The standard search ad: up to 15 headlines and 4 descriptions that Google combines and tests for each search.

Questions, answered.

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

How many keywords should an ad group have?

As many as share one meaning that a single ad can answer. That is often a handful to a few dozen. Split the group when an ad can no longer fit them all.

How many ads per ad group?

At least one responsive search ad, and a second gives you a comparison and a fallback.
