A framebreaker is a JavaScript code that prevents a website from being loaded within a frame or iFrame. Instead, the page "breaks out" of the frame and is displayed directly in the browser.

Why is this relevant on eBesucher?
When delivering advertising campaigns in the Surfbar, eBesucher needs to be able to verify whether a visitor was successfully delivered. If an advertised website contains a framebreaker, the following can happen:
- The eBesucher verification window is suppressed — the system cannot confirm the visit
- The advertised website is not loaded correctly
Do I need to mark a framebreaker?
Yes, for Surfbar campaigns: If your website contains a framebreaker, select the option "Page contains a framebreaker" with Yes when creating the campaign. This way eBesucher ensures that your page is still delivered correctly.
For Paid-to-click ads, no marking is needed — here all pages are opened directly in a new tab.
