What dropping CTRs tell us about the state of search
Click-through rates are falling, and everyone's trying to figure out what it means. The signal is not decline. It is redistribution.

Seer Interactive’s 15-month study (June 2024 to September 2025) looked at how Google’s AI Overview (AIO) affects performance. When AIO appears, organic CTR falls from around 1.6 percent to 0.6 percent. Paid CTR drops from 13 percent to 6.3 percent. Even without AIOs, both are still down significantly year on year.
This shift changes how marketers need to plan, allocate, and measure. The issue isn’t visibility loss, it’s visibility spread.
Actionable insights for marketing leaders
| Recommendation | Status | What to do | Why it matters |
|---|---|---|---|
| Redefine the discovery system | Still valid but broaden scope | Rebuild funnel maps around discovery touchpoints, not clicks. Include AI responses, video views, and voice queries as part of the discovery journey. | CTR now represents only one part of audience engagement. Broader discovery mapping prevents misdiagnosing performance declines. |
| Diversify where discovery happens | Make core strategy | Identify three discovery surfaces where your brand under-indexes but relevance is high. Build tailored visibility and content plans for each. | Over-reliance on Google Search is a structural risk. Discovery now spans social search, video, marketplaces, and conversational tools. |
| Balance the early-mover paradox | Refine for 2026 | Run small, structured experiments on emerging surfaces. Cap spend, define exit points, and document results as reusable learning assets. | Moving early gives data advantage but carries budget risk. Waiting protects spend but loses insight. Controlled testing balances both. |
| Protect authority as a ranking signal | Growing priority | Invest in authoritative content, structured data, and credible partnerships that strengthen brand trust and domain authority. | Authority now drives visibility. AI systems increasingly cite and prioritise trusted sources. |
| Modernise measurement and governance | Emerging practice | Conduct monthly visibility reviews across search, social, and AI interfaces. Track mentions, citations, and share-of-presence trends. Treat this as pattern recognition rather than precision reporting. | Measuring discovery is difficult but essential. Monthly reviews build fluency and help teams respond faster to how attention moves. |
The shift in search
Search is fragmenting into a wider discovery ecosystem. CTR decline is not a symptom of decay but evidence of redistribution.
In the future marketing leadership will focus less on where clicks land and more on how discovery unfolds across discovery surfaces. The work now is to stay visible, interpretable, and trusted as users move between platforms, interfaces, and AI systems.
Those who act early will own the data, context, and authority that shape the next stage of visibility.
