How to Test an OptinMonster Campaign

OptinMonster makes it easy to test an OptinMonster campaign and preview the design on your site before going live for your website visitors.

In this article, you’ll learn how to test and preview OptinMonster campaigns on your website.

Before You Start

Here are some things to know before you begin:

  • The Live Site Inspector feature provides confirmation of whether the current Display Rules configured for the campaign will allow it to appear on a specific URL. It does not guarantee the campaign is actively embedded and published on your site. We recommend you confirm the campaign is appearing live on your site by directly visiting the site after using the Test on Page feature.
  • The Preview feature ignores all Display Rules and will show the campaign immediately. This should be used to check the design of your campaign only and not the Display Rules.
  • The Live Site Inspector and Preview features are not available for Inline-type campaigns.

Live Site Inspector

OptinMonster allows you to quickly test your Display Rule configuration using our Live Site Inspector feature.

To use the Live Site Inspector feature to confirm your Display Rules, follow these steps:

  1. From the Publish view of the campaign builder, locate the Live Site Inspector field.
    Live Site Inspector field in the OptinMonster campaign builder.
  2. Enter the full URL of the page you want to test, then select the Test button.
    Test the campaign on your site with the Live Site Test feature.
  3. The URL entered will load in a modal window allowing you to test the Display Rules configured.
    For example, this campaign is set to appear on Exit-Intent so we test by moving the mouse toward the page boundaries:
    OptinMonster Test on Page feature for Exit-Intent campaign.
    If the campaign doesn’t appear as expected you may need to modify your Display Rules.
    Be sure to review the summary that appears on your page test to identify any roadblocks.

Preview Campaign

If you’re looking to preview the campaign’s design on your site you can easily do that before you publish your campaign.

To preview your campaign, follow these steps:

  1. From the Publish view of the campaign builder, select the Preview button next to the site you want to preview your campaign on.
    Preview your OptinMonster campaign.
    This button will not be available if the campaign type is Inline.
  2. A new tab or window will open to load your site and show the campaign for you to preview the design.


I’m using the Live Site Inspector feature, but my site isn’t loading. Why?

Test on Page feature in OptinMonster warning site couldn't be loaded.

If you’re receiving a warning that the site couldn’t be loaded when using the Test on Page feature, you’ll want to rule out the following causes:

  • The Embed Code hasn’t yet been added to your site.
  • Your site isn’t available to load over HTTPS.
  • Your site has a Content-Security-Policy header like X-Frame-Options: SAMEORIGIN
  • Your site took longer than 10 seconds to load.
