Five Tips for Publishers Facing the Zero Click Challenge
MEEDIA reports that publishers are losing referral traffic from Google as AI-generated summaries (AI Overviews) reduce the need for users to click through to websites. Citing a Seer Interactive study showing a 61% drop in organic CTR and a 68% drop in paid CTR for information queries with AI Overviews, Malte Gibbe (Seedtag) and Carsten Sander (BCN) outline five practical responses: (1) analyze crawl behaviour and implement Generative Engine Optimization (GEO) using server logs, (2) design content to encourage exploration, (3) combine paywalled and free content, (4) retain audiences via newsletters/logins and first‑party data, and (5) prioritise brand building so publishers appear in LLM answers. The article warns that sustained Zero Click effects could undermine precise targeting and the open ad ecosystem, while also noting publishers can use AI as a tool to develop new formats faster.
- MEEDIA published the article on 2026-08-10.
- A Seer Interactive study (September 2025) found that organic CTR for informational queries with AI Overviews fell by 61% and paid CTR fell by 68% compared with queries without AI Overviews.
