AI Search Isn’t Replacing Google, It’s Layering On Top

AI search isn’t pushing Google aside—it’s stacking right on top. Most users still turn to Google for quick answers or to reach websites fast, but when a search calls for more depth, tools like ChatGPT and Perplexity step in. People often start on Google, then shift to AI for extra context or details—Similarweb tracks that trend in its recent report More technology reviews.

Why AI Search Is Layering Over Google

According to Similarweb’s June analytics, Google keeps its place as the internet’s main gateway. There’s been no drop in Google’s overall traffic share in the past twelve months. Engagement with AI-powered platforms like ChatGPT and Perplexity has grown. These tools aren’t taking over core transactional or navigational searches. In many cases, users don’t visit Perplexity or ChatGPT directly—they land there from links found in Google searches.

User Case Studies: When AI Search Adds Value

Reviewers point out that AI-driven search really shines when it comes to summarizing long research or blending complex data sets for comparisons. Those tasks tend to stump Google’s one-sentence answer box. Professionals compiling market sentiment reports, or building technical FAQ content, often consult Google first—but then rely on generative AI to handle the detail work.

Impact on Publisher Traffic and Referral Trends

Data from Similarweb shows that publisher traffic from Google started dropping steadily in late 2025. This downturn hit reference sites, how-to pages, and product review categories hardest, with year-on-year numbers falling more sharply there. This isn’t because AI is replacing Google in the referral chain. It’s because Google now answers more questions right on its main page—like in those expanding answer boxes. And the rollout of new search features has only accelerated this trend, as recent reporting highlights.
