Retrieval and usability, control 10 of 18
R-10 Avoid intrusive overlays and obstructed content

Why it matters
Popups, sticky bars and ads that cover the page stop visitors from reading or using what they came for, especially on small screens. Search engines also assess the experience of the page, and content that cannot be reached is a poor basis for ranking or for use in an AI answer.
Evidence to review
- Mobile task recording, focus behaviour and overlay-state checks.
How to implement
- Test small screens and zoomed views.
- Ensure dismissal, consent choices and focus behaviour are usable.
- Check sticky elements, delayed popups and ad-induced layout shifts.
- Do not remove lawful consent safeguards merely to improve a performance score.
How UltimateSEO checks this
Automated. A check in the scan sets PASS or FAIL for this control, and reports UNKNOWN or BLOCKED when its input is missing.
States used: PASS, FAIL, UNKNOWN, NOT_APPLICABLE or BLOCKED. UNKNOWN is never shown as a pass. How states work.
