Confidence: Verified.

Why this matters for Candid: The clearest moment paid placement crowded the top of commercial SERPs. Pair with Google AdWords launched October 23, 2000 with 350 advertisers; shifted from CPM to CPC auction in February 2002 as the two-beat story of how paid search came to dominate the high-intent query top-of-page.
