How to Use the InactivitySensor™ in OptinMonster

OptinMonster makes it easy to recover abandoning website visitors and turn them into subscribers and customers. Our InactivitySensor™ feature allows you to grab the attention of disengaged and abandoning visitors on any device (mobile, tablet, and desktops).

In this article, you’ll learn how to use OptinMonster’s InactivitySensor™ to trigger a campaign.

Before You Start

Here are some things to know before you begin:

  • InactivitySensor™ is available with a Plus or higher subscription.
  • Visitors often stop interacting with your site (like scrolling, typing, or moving their mouse) when they’re no longer engaged with your content, and are about to close their internet browser. When this happens, InactivitySensor™ detects the lack of activity and triggers your targeted campaign.
  • InactivitySensor™ can be used with any popup type campaign (e.g. Lightbox, Fullscreen, Floating Bar, and Slide-In). It cannot be used with Inline campaigns.

Enable InactivitySensor™

When you create a campaign in OptinMonster you can capture abandoning leads by triggering it to appear using InactivitySensor™.

To enable InactivitySensor™ on your campaign, follow these steps:

  1. Navigate to the Display Rules tab in the campaign builder.
  2. Select the Edit button in the Summary view of your campaign’s Display Rules to modify them.
  3. Select the + Add button to add an AND rule, or the + Add a New ‘OR’ Rule button to add an OR rule.
  4. Click on the Select Rule field and select Trigger (When) from the sub-menu options.
  5. Select InactivitySensor™ from the menu.

    The rule will display as visitor inactive time once selected.
  6. Adjust the length of inactive time in seconds.
  7. When you’re finished, click Save.

Example Configurations

The most effective way to use this rule is to target desktop and mobile users separately since mobile and desktop visitors behave differently. Study your Google Analytics data for your site and test your how many seconds of inactivity produce the best results for your site.

Mobile visitors often scroll while they are actively engaged on your site, Also, many phone screens will dim after 30 or 60 seconds of inactivity on their own, and you’ll want your campaign to show before that happens. You will want to set a short inactive time period for mobile devices, like the one below:

  • Visitor inactive time is at least 10 seconds
  • Visitor’s device is mobile

For desktop users, your delay may need to be longer, as visitors’ monitors will not automatically dim or close like a mobile phone is more likely to do. Your Display Rules would look like this:

  • Visitor inactive time is at least 60 seconds
  • Visitor’s device is desktop


What’s the best way to use InactivitySensor™ to get more subscriptions?

The best way to use this rule is to use an OR condition with the exit-intent rule. This way, it will target users who get ready to leave OR stop browsing.

Next, it’s best to create split tests so you can determine the best time of inactivity for your site or type of visitor, for the most impressions, and more importantly a higher conversion rate.

You can also pair MonsterEffects and Sounds with InactivitySensor™ to further catch your distracted visitor’s attention.

Is this the same as Mobile Exit-Intent?

No, InactivitySensor™ triggers a campaign when a certain amount of time has passed and the visitor has not taken any action.

Mobile Exit-Intent is a separate feature that triggers a campaign when a visitor actively scrolls up on a mobile device, or clicks the browser “Back” button, depending on the rule’s sensitivity settings. Learn more about Mobile Exit-Intent.
