Generative Engine Optimisation Explained For Marketers
Organic clicks fall up to 58% when Google shows an AI summary. Learn how generative engine optimisation keeps your traffic alive. That figure explains why countless websites watched their traffic disappear during 2025.
The shift is structural, not seasonal. Therefore, recovery depends on understanding how search itself has changed.
What Is Happening To Search Traffic?
People now read the answer on Google and rarely click through. As a result, even top-ranked pages lose the visits they once relied upon.
Pew Research Center tracked the real browsing behaviour of 900 adults across 2025.
Users clicked a result only 8% of the time when an AI summary appeared. Without a summary, that share nearly doubled to 15%.
Moreover, links inside the summaries earned clicks just 1% of the time. In short, Google increasingly keeps the visitor on its own page.
Why Generative Engine Optimisation Matters Now?
The damage varies by industry, yet the direction never changes. Marketing agency Seer Interactive measured a 61% fall in organic click-through rates on informational queries.
Crucially, clicks fell even on searches without an AI summary. This suggests users now expect instant answers everywhere.
Ahrefs reached a similar conclusion across hundreds of millions of searches. Its December 2025 data confirmed the 58% drop for the top organic result.
In the UK, Authoritas found the same pattern hitting publishers hard. Indeed, a top-ranked page can lose roughly 79% of clicks when an overview appears above it.
This decline now looks like the new baseline, not a blip. So waiting for clicks to recover is no longer a strategy.
What Google AI Overviews Mean For Websites
Google AI Overviews summarise answers at the top of results. Discover how generative engine optimisation wins back lost visibility. Consequently, the classic prize of “position one” no longer guarantees traffic.
These summaries appear most often for informational searches. Therefore, how-to guides, definitions and comparisons face the steepest losses.
Longer, question-style queries trigger summaries far more frequently. Indeed, Pew found 53% of searches with ten or more words produced one.
Why Did Rankings Stop Protecting Traffic?
A page can still rank first yet earn almost no clicks. In fact, BrightEdge found just 17% of cited sources also rank in the top ten. Meanwhile, the summary above it satisfies the searcher completely.
Some news publishers report click losses near 79% when sitting below an overview. As a result, visibility now matters far more than position alone.
Does Generative Engine Optimisation Reach Beyond Google?
No, because the habit now spans the entire web. Seer found clicks falling even on searches that showed no summary at all.
AI chat assistants also answer many questions that once started on Google. Therefore, audiences increasingly expect answers without leaving a single screen.
Can Websites Still Win Visitors?
Yes, although the goal has shifted from ranking to being cited. Sites must now earn a mention inside the AI answer itself.
Original research and clear data give AI engines something worth quoting. Indeed, Ahrefs found the most-cited pages rarely match the old top ten. Google now rewards brands, official sites and data-rich sources. As Search Engine Land reported on the March 2026 core update, aggregators and thin pages lost ground.
Which Practical Steps Help Most?
Demonstrated experience signals genuine authority to both Google and AI tools. So businesses should publish tests, examples and measurable results.
Structured, well-cited writing also helps machines understand a page. Consequently, clear headings and credible references improve the odds of citation.
Fresh, regularly updated pages also earn more trust. Hence, refreshing strong content often outperforms chasing brand-new topics.
Conversion now matters more than raw clicks. In fact, WordStream data showed many industries improved conversion rates despite falling traffic.
How To Start Generative Engine Optimisation Today
First, they should track visibility and share of voice, not clicks alone. Otherwise, their dashboards will paint a falsely bleak picture.
Next, they should focus deeply on topics they genuinely understand. After all, depth and trust are exactly what AI engines reward.
They should also answer real questions in plain, direct language. Because clear answers are the content AI engines lift most readily.
Finally, they should treat being quoted as the new front page. The websites that adapt early will own the citation era.
