Overview
Account-level Exclusions help you show your ads to people who haven’t visited your site or made a purchase recently. It’s a smart way to drive new-to-brand growth and make your budget work harder by focusing on fresh audiences.
Use this feature when you:
Are launching a new product or offer and want a clean read on new-to-brand performance
Want to increase new-to-brand conversions
ℹ️ Note: By default, Account-level Exclusions are turned off. You can keep this setting, update it, or turn it on anytime.
If you're using MNTN Matched, keep in mind it excludes site visitors from the past 30 days — but your global exclusion settings will override it if set to a longer window.
⚠️ Warning: This feature only works with prospecting campaigns — not retargeting.
Use It
Access My Account.
In the top-right corner, click your brand name and select My Account from the dropdown.
Go to Exclusions.
In the left sidebar, click Exclusions and stay on the Audience Exclusions tab.
Choose who to block.
You can exclude:
Converters – people who completed a tracked action, like a purchase or signup
Site Visitors – people who’ve visited your site within the window you choose
Set your look back windows.
Pick a number between 1 and 365 days for each type aligning it with your customer journey and repeat purchase cycle.
💡 Tip: Start by defining what “new-to-brand” means for your business. Then, set your look back window accordingly. Not sure where to begin? Many brands start small with 30 days and refine over time based on performance trends.
⚠️ Warning: You can only exclude people going back as far as your MNTN Pixel has tracked them. No pixel = no exclusions.
Save your settings.
In the bottom-right corner, click Save Changes. Your exclusions will apply to all prospecting campaigns moving forward — and you can update them anytime.
Account-level Exclusions vs. Campaign-Level Exclusions
There are two ways to exclude audiences in MNTN. Each supports a different strategy:
Campaign-level first-party exclusions give you precision. These are built from your pixel data and let you include or exclude very specific groups within a single campaign. Because they rely on recent behavior, they focus on a shorter 30-day window and targeted segments.
Use campaign-level exclusions when you want to:
Control who sees a specific campaign
Exclude highly defined groups, like recent buyers of a specific product
Test and optimize performance between audience segments
Account-level Exclusions are designed for scale. These settings apply across all prospecting campaigns and block recent visitors or converters based on your pixel history for up to 365 days.
Use account-level exclusions when you want to:
Focus your budget on reaching new customers
Prevent overlap across prospecting campaigns
Maintain a consistent new-to-brand strategy
Make broad updates without editing each campaign
Pro Tips
Already using first-party exclusions at the campaign level?
Already using first-party exclusions at the campaign level?
If you've excluded a site visitor audience (like past purchasers or recent visitors) directly within a prospecting campaign, MNTN will automatically apply the longest exclusion window between that audience and your Global Exclusion setting to ensure full coverage.
🔍 Example: If your campaign-level exclusion is set to 30 days and your Global Exclusion is 120 days, MNTN will use the 120-day window.
Only want to exclude converters?
Only want to exclude converters?
Toggle ON Converter Exclusions (make sure Site Visitor Exclusions remains toggled OFF). Then enter the number of days you want to exclude in the Converter Exclusions field.
This ensures only converters are excluded and not recent site visitors.
Quick Answers
Why did conversions drop after turning on Global Exclusions?
Why did conversions drop after turning on Global Exclusions?
That’s normal! It means your budget is working harder to reach new customers. Over time, this helps improve your new-to-brand performance and make your spend more efficient.
Why isn’t my full exclusion window taking effect right away?
Why isn’t my full exclusion window taking effect right away?
Your Account-level Exclusions are only as effective as your MNTN Pixel’s history.
Even if you set a 365-day window, MNTN can only exclude people the Pixel has tracked. So if your Pixel has only been active for 100 days, your exclusions will cover that 100-day window and continue building day by day until the full 365 is reached.
What happens if I change my exclusion window later?
What happens if I change my exclusion window later?
When you update your exclusion settings, the change only affects impressions going forward — not retroactively. That means any visits or conversions tied to impressions served before the change may still appear in reporting, even if those users are now excluded under the new window.
