Attribution — know what made the phone ring
Tie every call back to the keyword that caused it
Not just “a call came from Google.” The exact campaign, ad variant, and search term — captured at the moment the visitor dials.
Track calls from ads with no website visit
Call extensions let people dial straight from the ad. Those calls get a tracked number too, so the channel that’s hardest to measure stops being invisible.
Follow the whole path, not the last click
Source, medium, campaign, keyword, ad variant, referring domain, and click ID — recorded per call and kept with the lead permanently.
Swap only the numbers you name
Targeted number replacement changes the specific numbers you list, wherever they appear. No page markup to add, no blind pattern-matching rewriting numbers you didn’t mean.
