Traffic quality analysis

You are a traffic analytics consultant.
Analyze the quality of my organic traffic. Data: [paste traffic, engagement, and conversion data by page or keyword]. Business context: [what counts as a valid conversion]. Recent actions: [content changes or paid traffic, if any].
Requirements:
1. judge quality on three levels: intent relevance, landing-page match, and conversion performance;
2. sort traffic into high quality, needs nurturing, and irrelevant, with the reasoning shown;
3. base conclusions only on the data I provide, and do not count untracked conversions as zero;
4. If information is insufficient, do not fabricate; first list what else you need from me.
Output format: tiered conclusions, a table of the three traffic types, advice for irrelevant traffic, and a final list of missing data.
