There are so many reasons to keep campaign construction simple, but the easiest of those reasons to understand is this…
All of your extra and unnecessary campaigns, ad sets, and ads, are sucking away your budget and either making it difficult to evaluate results or hurting your performance.
Limit the Number of Campaigns
If you don’t need to create those extra campaigns, don’t. It makes sense to create multiple campaigns that have different goals. But, avoid creating multiple campaigns that have overlapping goals.
In a perfect world, you could have one campaign for sales, one for leads, and one for top of funnel.
Limit the Number of Ad Sets
If you don’t need to create those extra ad sets, don’t. There was a time when this made a lot more sense. We created multiple ad sets to segment by optimization, audience, or even placement. But doing this is far less necessary these days — though it hasn’t stopped advertisers from doing it.
Segmenting by audience is often overkill due to the expansion of targeting inputs — either because of Advantage+ Audience or one of the Advantage expansion products.
There are always exceptions, but make a conscious effort to limit unnecessary ad sets when possible.
Number of Ads
If you don’t need to create those extra ads, don’t. You should submit multiple copy and creative options, though there are some good, strategic ways to do it.
One is to create multiple ads within an ad set. But Meta says that there’s no benefit after you’ve created six. This only applies to manual campaigns and not Advantage+ Shopping, of course (Meta encourages more creative there).
You could otherwise use Dynamic Creative or the Text Variations feature.
Stretching Your Budget
Every time you create that extra campaign, ad set, or ad, it waters down your results. It makes them less meaningful. Small sample sizes mean that your evaluation can be altered drastically by a small handful of actions.
This added complexity impacts how much budget you can dedicate to each of your assets. Assuming you don’t have an unlimited budget, it’s the difference between spending $200 per day on one ad set of $20 per day on 10.
If your ad sets aren’t exiting the learning phase, you’re evaluating ads based on small sample sizes, or you’re not getting great results overall, start consolidating.
Your results are more likely to be meaningful and you may even improve performance.
