What you’ll learn

From page load to adTrace how an ad request becomes a set of eligible candidates and then a selected creative.An ad slot requests a creative, targeting narrows the candidates, and an auction compares eligible bids and line items.
Signals, measurement, and limitsDistinguish contextual signals, tracking technologies, consent boundaries, and outcome measurements.Context, cookies, consent, impressions, clicks, and purchases describe different parts of online advertising and should not be collapsed into one claim.

Questions this course answers

What usually happens before bids are compared?

Targeting and delivery rules first narrow the candidates that can compete.

Match each stage to what it describes.

These are connected events, but they are not interchangeable measurements.

Put these events in a sensible order.

The sequence keeps the technical mechanism separate from later outcomes such as clicks or purchases.
