Data source — every number on this tab comes from the Google Search Console API for the selected property. It covers organic Google Search only: no paid search, no other search engines, no other channels. Figures can differ slightly from the Search Console UI because the API applies its own privacy filtering.
Clicks — drivers and drainers are ranked by change in clicks, and the bold number on each row is clicks. Impressions and CTR appear in the headline KPIs only.
PP — Previous Period: the same number of days immediately before the current period.
LY — Last Year: the same period shifted back 364 days, so it lands on the same days of the week (a Monday compares to a Monday). This is why LY dates don't match Search Console's calendar year-over-year.
pp — percentage points. Used for CTR: a move from 4.26% to 5.03% is +0.77pp, which is +18% relative. They are not the same thing.
K / M — thousand / million.
Green / red — increase / decrease versus the comparison period. Green is not automatically good (rising impressions with falling clicks is a warning sign).
Headline KPIs are site-wide totals and match the Search Console UI. Brand / non-brand figures are query-level, so they sum lower — see the note on that card.
Drivers / Drainers — pages or queries with the biggest absolute click gain / loss. Ranked by the size of the change, not by total clicks.
Decayed — had clicks in the comparison period, none now. New — has clicks now, none in the comparison period.
