Alphabet Q1 2026 Earnings Show Google Network Revenue Drop, AI Search Changes

Alphabet’s first‑quarter 2026 earnings report revealed a mixed picture for the tech giant. Google Search and Other revenue rose 19 % year‑over‑year to $60.4 B, while the Network segment – which includes AdSense, AdMob and Google Ad Manager – fell to $6.97 B, the first time the unit has dipped below $7 B. The decline in Network revenue reduced its share of total ad revenue from 12 % to 9 %, even as programmatic advertising grew 20.5 % to $162.4 B in 2025. A January 2025 outage at the ad‑exchange further hurt publishers, with 50‑90 % drops in eCPM/RPM for AdSense sites. Meanwhile, Microsoft’s Bing platform announced it has reached 1 B monthly active users, with search‑ad revenue up 12 % and an edge browser share that has grown for 20 straight quarters.

The earnings data come against a backdrop of rapid change in how users find information. Google’s AI Overviews, introduced in May 2024, now appear on roughly 25 %–48 % of queries. Studies show that when an AI Overview is present, organic click‑through rates fall 61 % and paid click‑through rates fall 68 %, yet brands mentioned in the Overview receive 35 % more organic clicks and 91 % more paid clicks. In response to publisher complaints about low click‑through rates – only 8 % for AI results versus 15 % for non‑AI – Google added five new link‑surface features this week, including inline links beside supporting text, an “Explore new angles” section, a Perspectives section that surfaces Reddit and forum quotes with creator names, desktop hover previews, and subscription labels for paid content. None of these updates provide new click‑tracking in Search Console, leaving publishers unable to isolate AI‑related traffic.

Beyond Google, Gartner predicts a 25 % drop in traditional search volume by 2026, yet Google’s search revenue grew 17 % year‑over‑year to $63 B in Q4 2025. AI tools such as ChatGPT and Perplexity are driving 2.5 B prompts a day, but still account for less than 1 % of U.S. web traffic. Still, AI‑driven traffic converts at more than four times the rate of organic traffic, and 88 % of AI Mode citations are not in the organic SERP. Brands and agencies are now urged to audit and optimize for AI visibility alongside traditional SEO, as ignoring the new surface risks losing early‑stage intent and trust signals.
