How AI Overviews are changing UK search traffic in 2026

Google AI Overviews — the AI-generated summaries that appear above traditional search results — are reshaping how UK users interact with search. For businesses that rely on organic traffic, the impact is measurable and accelerating.

What AI Overviews Are

AI Overviews are Google implementation of generative AI in search results. When a user searches for an informational query, Google now often displays a synthesised answer at the top of the page, compiled from multiple sources. The user gets an answer without clicking through to any website.

The Traffic Shift in Numbers

Studies from 2025 and early 2026 indicate that AI Overviews appear on approximately 30-40% of informational queries in the UK. When an AI Overview appears, click-through rates to organic results drop by an estimated 25-40%, depending on the query type.

The most affected queries are definitional, comparison, and how-to queries — precisely the content that many businesses have invested heavily in for SEO purposes.

Which Industries Are Hit Hardest

Industries with high volumes of informational search traffic are most affected: health and wellness, financial services, legal information, technology and SaaS, and educational content.

Why Bottom-Funnel Content Is More Resilient

AI Overviews are strongest on informational queries and weakest on transactional and navigational queries. Users who search for “marketing consultancy London” want to take action — that requires visiting a specific website.

Content targeting purchase intent, service enquiries, and specific actions retains its traffic value. The services page, contact page, and schedule of charges are examples of resilient bottom-funnel content.

What to Publish Instead

• Publish original data. AI Overviews cite sources. Original research and case studies are more likely to be cited than generic explanations.
• Target specific, long-tail queries. Broad queries trigger AI Overviews. Specific, niche queries often do not.
• Optimise for GEO. Make sure AI cites you. See our guide to Generative Engine Optimization.
• Build direct channels. Email, LinkedIn, and direct relationships are not affected by AI Overviews.

Frequently Asked Questions

Can I opt out of AI Overviews?

Google offers a nosnippet meta tag, but using it may also reduce your visibility in traditional search results.

Should I stop creating informational content?

No. Informational content still drives brand awareness and supports GEO. But supplement it with transactional and original-data content.
