Ad Set
In short
An ad set is the middle level of an ad campaign: this is where you define the audience, placements, optimization goal and often the budget for several ads.
Also known as: ad group
An ad set is the middle level in the structure of an ad campaign: between the campaign with its objective and the individual ads. Meta calls it an ad set; Google Ads, TikTok and Microsoft Ads call the equivalent level an ad group.
What is set at the ad set level
On Meta, the ad set defines:
- Audience: Location, age, custom audiences, detailed targeting or Advantage+ audience.
- Placements: e.g. Facebook feed, Instagram Stories, Reels.
- Optimization event: What the algorithm optimizes for, such as lead or purchase.
- Budget and schedule: Unless the budget is set at the campaign level.
Google Ads works a bit differently: budget and bid strategy usually sit at the campaign level, and the ad group mainly bundles keywords with matching ads. LinkedIn calls its levels campaign group, campaign and ad.
Example
An insurance broker runs a lead campaign with a $4,000 budget and two ad sets: a custom audience of website visitors (retargeting) and a broad audience aged 30 and up. The retargeting ad set brings in 40 leads at $25, the broad one 80 leads at $37.50. Each produces 6 closed deals. So a deal costs $167 from retargeting and $500 from the broad audience. Only this number tells you where extra budget makes sense.
Evaluating ad sets in lead generation
Because every ad set has its own audience, this is often where lead quality differs most. The ad platform, however, only shows you leads and costs, not which leads ended up buying.
LeadMetrics syncs campaigns, ad sets and ads with daily spend from Meta, Google Ads, TikTok, LinkedIn and Microsoft Ads (Beta), and attributes leads, deals and revenue to them. In the dashboards you drill down from channel to campaign, ad set and ad. Details on the Meta connection are on the Meta Ads page.
Common mistakes
- Too many small ad sets: The budget gets split up and no ad set collects enough conversions.
- Overlapping audiences: Several ad sets compete for the same people.
- Optimizing for cost per lead only: The cheapest ad set isn't automatically the one with the most deals.
