Blocking mobile app placements in Google Ads requires a direct adjustment to your campaign settings to filter out unwanted inventory. Advertisers can exclude specific apps or entire app categories to ensure their budget is spent on high-intent environments rather than accidental clicks on mobile games or utility apps. By using placement exclusions, you gain control over where your display or video ads appear across the Google Display Network, which helps maintain a cleaner traffic source for your campaigns.
Why should you block mobile app placements?
In a typical account, mobile apps often generate high impressions but low conversion rates. This is frequently due to users clicking ads accidentally while playing games or navigating mobile interfaces. When your ads run within these applications, you might see a spike in traffic that does not lead to actual sales or leads. By blocking these placements, you redirect your resources toward websites or apps that align better with your target audience’s behavior. This strategy helps to improve your click-through rate and reduces the cost per acquisition by filtering out low-quality interactions that rarely result in a meaningful outcome for your business.

Another reason to consider this change is the nature of ad engagement in mobile apps. Many users interact with apps in a distracted state, leading to unintentional taps on banners or interstitials. If you are running a performance-based campaign, these stray clicks can deplete your budget quickly without providing a return. Monitoring your placement reports allows you to identify which specific apps are draining your funds. Once you pinpoint these underperforming sources, you can apply exclusions at the campaign or account level to prevent future waste.
How can you exclude mobile app categories?
Google Ads offers an efficient way to remove entire categories of mobile apps from your targeting scope. This is particularly useful if you want to avoid appearing in broad categories like ‘Games’ or ‘Utilities’ without having to select each app individually. By navigating to the ‘Content’ section in your Google Ads dashboard, you can adjust your placement exclusions to filter out specific app types. This broad approach covers thousands of apps simultaneously, providing a quick fix for campaigns that are suffering from poor performance across mobile inventory.
Steps to exclude app categories
- Sign in to your Google Ads account and select the campaign you want to modify.
- Click on the ‘Content’ tab located in the left-hand menu.
- Select ‘Exclusions’ and then click on ‘Placement exclusions’.
- Choose the ‘App categories’ option to see a list of available app types.
- Check the boxes next to the categories you wish to block, such as ‘Games’ or ‘In-app’.
- Save your changes to apply the new exclusions to your selected campaign.
Is it possible to block specific mobile apps?
Yes, you can target individual mobile apps for exclusion if you find that only a subset of your traffic is problematic. This is helpful when you identify specific game apps that consistently fail to convert but want to keep your ads running on other, more relevant applications. You can use the ‘Where ads showed’ report to look at individual placement data. If you notice a specific app ID or name consistently consuming your budget without delivering results, you can add that specific placement to your exclusion list to stop it immediately.

This granular control is essential for long-term optimization. While blocking entire categories is a good starting point, looking at individual placements helps you retain potentially profitable apps. For example, a sports-related app might be a great place for your ads, even if most gaming apps are not. By reviewing your performance reports once or twice a month, you can keep your exclusion list updated. This practice ensures your campaign remains lean and focused on high-quality inventory rather than just blocking everything by default.
How Alien Road applies placement filtering
At Alien Road, we manage campaign performance by prioritizing placement auditing as a core part of our workflow. When we take on a new project, we conduct a baseline analysis of the account’s placement history to identify where spend is being wasted. We look for high-impression, low-conversion patterns that are common in mobile app environments. Once we verify that these placements are indeed ineffective for the client’s goals, we implement a multi-layered exclusion strategy that covers both broad categories and specific, high-cost apps.
Our process involves setting up a recurring review schedule to maintain traffic quality. We do not just apply a ‘set and forget’ policy; instead, we monitor new placements that Google’s algorithm may discover over time. For example, if a client is running a lead generation campaign, we watch the placement reports closely for the first few weeks. If we see a pattern of clicks from irrelevant utility apps, we block those placements immediately to protect the remaining budget. This active management ensures that our clients’ investments are directed toward sites where their message is actually heard.
What to watch for in your placement reports?
Your placement reports are the most reliable source of information for deciding what to block. You should pay attention to metrics like conversion rate, cost per click, and engagement duration. A placement that shows thousands of impressions but zero clicks, or a high number of clicks with a bounce rate near 100 percent, is a strong candidate for exclusion. By filtering your data by these metrics, you can quickly identify the ‘noise’ in your campaign and focus your budget on the ‘signal’ that generates actual business value.
Checklist for placement optimization
- Review the ‘Where ads showed’ report every 30 days to identify poor performers.
- Sort placements by cost to see which ones are the most expensive.
- Check for high-impression placements that have a zero percent conversion rate.
- Compare the performance of mobile apps against desktop websites to identify discrepancies.
- Update your account-level exclusion list if you find certain apps that should never receive your ads.
Where to start this week
To improve your campaign efficiency this week, begin by analyzing your ‘Where ads showed’ report for the last 90 days. Identify at least five to ten mobile apps that have spent a significant portion of your budget without producing a single conversion. Once identified, add these to your placement exclusion list at the campaign level. After making these changes, monitor your account for the next seven days to observe the impact on your cost per conversion. This simple, data-driven action is a reliable way to start cleaning up your traffic and getting more value from every dollar spent on Google Ads.
Additionally, consider checking your campaign settings to see if your Display Network targeting is too broad. If you are running an automated campaign, ensure that you have set clear conversion goals so the system has enough data to learn which placements are truly valuable. While automated bidding is helpful, it still benefits from human oversight. By pruning the low-quality placements manually, you provide the Google algorithm with a higher quality pool of data to work from, which can lead to better overall performance for your advertising efforts.
