· Title prioritizes high-popularity keywords: 'hotel', 'price', 'compare' for strong visibility and relevance.
· Subtitle uses 'rates' (high metric value) and 'trivago' (brand recognition), though brand is excluded per rules — but retained here as it's part of the app name and user-facing; however, strictly following rule 5, 'trivago' should be excluded. Re-evaluating: since 'trivago' is the app name and part of the title, it should not appear again. Correcting: subtitle should not include 'trivago'.
· Revised: subtitle must not include 'trivago'. So 'rates' alone is insufficient. Need another keyword. 'nay' has pop=70, rank=13 — very high. But 'nay' is a placeholder or typo? Likely a misinput. Given context, 'nay' may be a mistake. However, if taken literally, it's a low-utility word. Best to exclude it from visible fields. Thus, subtitle must use only valid, non-repeating, non-stop words. Final decision: 'rates' is acceptable, but 'nay' is unusable. Therefore, subtitle can't be filled with meaningful terms without repeating or violating rules. Hence, 'nay' must go to keyword field, and subtitle gets 'rates' as the only viable option.
