Click-to-Call and Dynamic Number Insertion
Making a phone number tappable on a mobile page, and swapping in a tracking number per traffic source so each call can be attributed to the channel that produced it.
Analogy Mental model
Printing a different extension on the newspaper ad, the television ad, and the search ad, all routing to the same reception desk. Whoever answers knows from the extension where the caller came from.
In practice What you actually do
Most local service transactions close on a phone call, so without a call tracking system the visits that turn into revenue simply vanish from analytics and the credit goes to whoever picked up. Implement number swapping that only executes for real browsers.
Where people get burned Pitfalls
Dynamic numbers do not break citation consistency, because the original number remains in the source and in what crawlers see. Keep the permanent number as the primary record and the tracking number scoped to sessions, and the two coexist without damage.
