The shift to AI search, in the numbers.

For 20 years, Google gave you ten links to compete for. Now AI gives a customer 2 or 3 named businesses. If you’re not one of them, you’re invisible in that conversation — and you’ll never see the lead you lost.

Below are the numbers behind that claim. Every one carries its source. Read the full breakdown in the Understanding GEO Search whitepaper.
