When you create a Facebook ad campaign, you have limitless options. You can roll with defaults or make manual changes. When it comes to where your ads appear, which placements should you choose?
When creating your ad setAn ad set is a Facebook ads grouping where settings like targeting, scheduling, optimization, and placement are determined. More, Facebook uses “automatic placements” (or now Advantage+ PlacementsFormerly known as Automatic Placements. When you utilize Advantage+ Placements, Meta will automatically optimize which placements are used and when to get you the most results for your budget. More) by default. But, you can manually select placements as well.

What should you do? Let’s investigate…
Advantage+ Placements
When you use Advantage+ Placements, Facebook will “maximize your budget” and automatically distribute your ads across placements that will lead to the most results. Of course, that doesn’t necessarily mean using only the most effective placements. Cost and competition will matter, too.
The Advantage+ Placements selection removes thinking from this step. If you trust how Facebook optimizes and shows your ads, just leave it be.
You may have noticed that during the past year or so, Facebook is pushing more and more to leave these default automations as they are.
The Problem
We’ve discussed the potential pitfalls of Facebook ads optimization before, and it comes up here once again.
When you’re optimizing for an action, Facebook rarely cares about the quality of that action (there are a few exceptions). Facebook only cares that they get you the most actions you ask for at the lowest cost.
This can result in some issues, particularly if you’re optimizing for top-of-the-funnel and surface-level results (like link clicksThe link click metric measures all clicks on links that drive users to properties on and off of Facebook. More). Facebook wants to get you that action. That’s it. They don’t care what happens next.
I’ve found that the Audience NetworkAudience Network is a network of mobile apps that have been approved to monetize their apps with ads. This is how you can show your Meta ads to people while they are away from the Meta family of apps. Audience Network and associated groups are among your placement selection options in the ad set. More placementA placement is a location where your ad is shown. Examples include Facebook's mobile Feed, Messenger, Instagram feed, Audience Network, right-hand column, and more. More is notorious for accidental clicks, click fraud, and overall low-quality clicks. I’ve also discussed how the Audience Network Rewarded Video placement can be problematic for ThruPlay optimizationThe Performance Goal is chosen within the ad set and determines optimization and delivery. How you optimize impacts who sees your ad. Meta will show your ad to people most likely to perform your desired action. More since those who watch that video are incentivized to do so, in exchange for something of value (completely unrelated to your product).
When this happens, Facebook may push more of your budgetA budget is an amount you're willing to spend on your Facebook campaigns or ad sets on a daily or lifetime basis. More to these placements in an effort to get you more of the action that you want. You, of course, don’t necessarily want that.
Manual Placement Selection Issues

It would seem that the easy answer is to use the manual placements option. The answer isn’t always so clear.
I’ve heard from advertisers who automatically turn off placements like AudienceThis is the group of people who can potentially see your ads. You help influence this by adjusting age, gender, location, detailed targeting (interests and behaviors), custom audiences, and more. More Network and Right Hand Column, regardless of the optimization. I don’t think this is the right approach as a catch-all.
As mentioned above, there are times when Facebook optimizes for quality events (purchase or value, for example). In those cases, click fraud, accidental clicks, and incentivized video views won’t mislead Facebook to use that placement. If you don’t get the quality actions, Facebook will stop using that placement (in theory).
Sometimes, advertisers can micro-manage in this case. They’ll choose only the news feed placement, for example, assuming it is the most valuable placement.
Even if news feed were the most valuable placement, there are reasons to include other placements as well.
Every Placement is Different
The copy and design requirements are different for every placement. The action rate for every placement is different. But, most importantly, so is the cost.
In other words, you may get the highest action rate from news feed. But, the cost just to reachReach measures the number of Accounts Center Accounts (formerly users) that saw your ads at least once. You can have one account reached with multiple impressions. More people there may be high, too.
Meanwhile, the right hand column may provide the lowest action rate. But, the cost to reach people there may be the lowest.
Not to mention that the competition may be high and inventory low in news feed. If you force Facebook to use only that placement, you may inadvertently increase costs. And you may struggle to reach as many people as you potentially could otherwise.
Every placement (in most cases) has its role. The question is whether Facebook properly distributes your budget by placement if you allow it to automatically.
Use BreakdownsBreakdown is a way to get insights into your ad performance related to time, delivery, action, or dynamic creative element. More
One way to check how Facebook is distributing your budget is to use the Breakdown feature in Ads Manager. Click the drop-down and select “Placements” under “Delivery.”

When you do this, look beyond the total number of actions. Focus on Cost Per Action, but also get a sense of whether that cost is over a large enough sample size to care.
The main reason to use Breakdowns here is to see if Facebook is blowing your budget on one placement that simply isn’t working. Otherwise, Facebook should use every placement to experiment with how people respond. Over time, Facebook will learn from those results.
One thing to keep in mind is that you may not see results for all metrics when using breakdowns depending on the optimization due to iOS 14+ changes.
What Should You Do?
First, I’d say that the inexperienced advertiser should always keep it simple. Use defaults whenever possible. In this case, trust Advantage+ Placements.
I’d also say that Advantage+ Placements is likely fine when optimizing for conversionsA conversion is counted whenever a website visitor performs an action that fires a standard event, custom event, or custom conversion. Examples of conversions include purchases, leads, content views, add to cart, and registrations. More. Overall, you can overthink this. The more you micro-manage, the more likely you are to force up costs.
Neither approach is perfect. They both have their potential issues.
Use the Breakdown by Placements feature. Respond to any glaring issues. Apply what you learn to future campaignsThe campaign is the foundation of your Facebook ad. This is where you'll set an advertising objective, which defines what you want your ad to achieve. More, but always keep an open mind.
