Search in 2027: what the numbers already tell us

Let's start with the boring truth. StatCounter put Google at 89.94% of worldwide search engine market share in September 2026. Bing was at 5.29%. Everything else was a rounding error.

Google itself said in 2025 that it handles more than 5 trillion searches a year, and on its Q2 2026 earnings call it reported search revenue up 17% year on year. So if someone tells you to stop doing SEO because "nobody Googles anymore", you can safely ignore them.

But market share only tells you where people type the question. It does not tell you what happens next. That is where things have changed.

SparkToro has tracked for years how many Google searches in the US end without a click to any website. The share keeps climbing.

Two in three searches now finish on Google's own page. Sometimes that is because the person got a phone number, a map or a quick fact. Increasingly it is because an AI summary answered the question.

Publishers have felt it most. Chartbeat data reported in March 2026 showed Google Search referrals to publishers down 34% during 2025, and down 60% for small publishers.

This is the other half of the picture. AI assistants are no longer a side habit for early adopters.

OpenAI counts differently: it reported more than 900 million weekly active users for ChatGPT in February 2026. A weekly number that size is not comparable to the monthly numbers above, which is why it is not in the chart, but it tells the same story.

And it is not only tech people. Pew Research found in early 2026 that nearly half of US adults use AI chatbots, up from about a third in 2024, and 42% use them to look up information.

Here is where you need to hold two facts at once.

Fact one: AI referrals are still small. SE Ranking measured ChatGPT referrals at 0.32% of total website traffic in May 2026, across more than 100,000 sites. That was a record, and it is still a third of one percent.

Fact two: the growth rate is steep. Similarweb counted an average of 770.7 million visits a month from AI platforms to websites between June 2025 and May 2026, up 117% year on year. Adobe found that AI-sourced visits to US retail sites in May 2026 converted 54% better than other traffic.

Small, growing, and unusually qualified. That is a channel worth preparing for, not one worth betting the business on yet.

Gartner predicted in February 2024 that traditional search engine volume would drop 25% by 2026. We are in late 2026 now, and nothing we can measure publicly shows a drop of that size. Google's share and revenue certainly do not.

But the spirit of the forecast has held up better than the number. People are not searching less. They are clicking less, and they are asking some questions somewhere else.

The newer forecasts are about value rather than volume. Semrush projected in 2025 that AI search visitors would overtake traditional search visitors in early 2028 for marketing topics. McKinsey estimated that $750 billion in US revenue will flow through AI-powered search by 2028. Treat both as informed guesses. The direction is consistent; the dates are not guaranteed.

If you run a business rather than a newsroom, here is the honest summary.

Keep doing SEO. Google is where nine in ten searches still start, and a large share of what AI assistants cite comes from pages that are crawlable, clear and well structured.

Stop measuring success by clicks alone. If two thirds of searches end on the results page, being the named source in the answer matters even when nobody visits. Track branded search, direct traffic and how often your business is mentioned in AI answers.

Write for the question, not the keyword. Short, direct answers near the top of the page, followed by the evidence. That format serves a person skimming, a featured snippet and an AI summary at once.

And keep your facts consistent everywhere. Name, address, services, prices, opening hours. Assistants stitch answers together from many sources, and a business that contradicts itself gets left out.
