Sometimes you may experience latency when your RTP campaign displays on your webpage and pages appear to load slowly. The following checklist will help you find issues that may be contributing to campaign latency.



Troubleshooting Checklist:


  • Verify that you are using the most updated RTP tag version on your website.

    • Go to your website > Right click on the page and select "View Page Source" > Search for 'RTP' to find your tag.

    • Verify that this tag matches the code provided for your instance. You can find more information on finding your RTP tag here.


  • Verify that the RTP tag is the first script in the header of your pages – between the <head> </head> tags.

    • If the tag is not in the recommended placement, follow the documentation on deploying the RTP tag. Moving the tag to the recommended placement will resolve most latency issues.


  • Are you using a tag Manager?

    • Using a tag manager for your RTP tag is known to affect campaign performance.
    • If you are experiencing campaign latency while loading the RTP tag via a tag manager, we recommend moving the tag into the code itself. You can find more information on deploying the RTP tag here.


  • Check the campaign itself.

    • Campaign customizations that load additional content can contribute to increased RTP campaign loading times. For example, a campaign with an embedded Marketo form may experience a small delay as the campaign loads the form from your Marketo instance, so it's one code loading another script, which then loads another. That can cause latency while the browser catches up, so the simpler you can make the code, the better.
