Unique visitor: a visitor counted once for comparison of sources.

Lead: a person or company that left a contact or performed an action that allows the advertiser to continue the sale.
Report: a campaign-level comparison of placements by clicks, unique visitors, events, leads, costs, and quality signals.

CPC: cost per click. Useful for first comparison, but a cheap click is not always a good lead.
CPL: cost per lead. Shows how much one lead cost for a placement or campaign.

CTR: click-through rate. Shows the share of impressions that became clicks when impressions are known.

Traffic quality signal: a cautious warning such as suspicious bursts, repeated visits, bot-like behavior, or clicks without later events. It is not proof of fraud.
