How it works
A click identifier links events to Google Ads activity, subject to consent settings and appropriate data handling. Marketing attribution links traffic sources to telephone enquiries. Results depend on reliable identifiers, attribution windows and accurate conversion recording.
Business example
Marketing systems store GCLID where permitted and use it to connect qualified offline sales with ad clicks.
What to consider
Distinguish attribution from proven causation. Account for consent, incomplete customer journeys and calls without a known marketing source.
