Page intersection: the Google keywords that up to 20 pages all rank for (minus keywords of up to 10 excluded pages), with each page's position, URL and estimated traffic plus search volume, CPC, difficulty and intent; up to 100 keywords in one $0.048 call. Use when you need the shared keywords of competing pages. Rows are capped at 200 / pages (2 pages: 100, 20 pages: 10). No shared keywords returns empty results (still charged). Bad input is free; upstream errors are not charged.
