Testing a Sticky Section Menu on a Long Landing Page

Primary action completion rate

Compare whether adding navigation changes completion of the target action.

• Navigation usage rateCheck whether visitors use the links.
• Section visibilityMeasure actual visibility; jumping to a section does not show that intervening content was read.
• Time to reach a target sectionIf the task is known, measure time to the predefined section; do not infer intent from every jump.
• Page exit rateCheck whether exits after jumping to one section increase.

• NavigationAdd one fixed navigation element linked to existing sections.
• Keep constantKeep section names, order, content and CTA unchanged.
• DestinationKeep the heading of the destination section visible.
• MobileLeave enough space for the main content on mobile.
• Separate testA sticky table of contents or new section labels is a separate comparison.

1. 1Do not rewrite section headings when adding navigation.
2. 2Do not make sticky navigation large enough to cover important screen space.
3. 3Do not assume low usage means it is useless; it may matter to a specific visitor.
4. 4Make sure anchor targets do not hide under a sticky heading during scroll.
5. 5Keep keyboard navigation accessible.
