Google has initiated its June 2026 spam update while providing new clarity on how AI search impressions are measured and the limitations of third-party SEO optimization tools.

Key Points

• Google began rolling out its June 2026 spam update on June 24, which specifically targets efforts to manipulate generative AI responses and citations.
• Search Advocate John Mueller clarified that Search Console impressions for AI Overviews only count links when they are visible or opened by a user.
• Advanced Web Ranking data for Q1 2026 shows desktop click-through rates rising while mobile top-position performance declined by 2.2 percentage points.
• A Similarweb report found that 55.9% of traffic following a ChatGPT recommendation arrives via branded search rather than direct referral links.
• Google VP Brendon Kraham confirmed that the company does not evaluate third-party SEO tools and that no external vendors have access to internal ranking metrics.

Why it Matters

These updates highlight a shift in how search visibility is measured as AI-driven interfaces become more prominent in user behavior. Businesses must adapt their tracking strategies to account for branded search and indirect AI influence, as traditional attribution models often fail to capture the full impact of AI recommendations.
