In 2024, Gartner predicted traditional search volume would drop 25% by 2026 as AI alternatives emerge. We're three months into 2026 — here's what the actual data shows about whether the prediction is on track, ahead, or behind, and what SaaS founders should do about the answer.

Gartner's February 2024 forecast — that traditional search engine volume would drop 25% by 2026 — is directionally correct but the specifics are more nuanced than the headline suggests. As of Q1 2026, Google's raw search volume has NOT dropped 25% — it is slightly up year-over-year. But the volume of searches that result in a click to a third-party website has compressed substantially because of AI Overviews, and standalone AI search engines are absorbing informational queries that used to land in Google. The net effect on SaaS traffic is closer to Gartner's prediction than Google's own query counts would suggest.
In February 2024, Gartner published: "Gartner Predicts Search Engine Volume Will Drop 25% by 2026, With AI Chatbots And Other Virtual Agents." The research note argued that the combination of generative AI chatbots, AI-integrated search surfaces, and specialized AI agents would reduce the volume of traditional search engine use by roughly a quarter by end of 2026.
The prediction was widely read — and widely misread. It was not a prediction that Google would disappear. It was a prediction about traditional search behavior shifting to alternative AI surfaces. The distinction matters.
"Search volume" can mean at least three different things. Evaluating Gartner's prediction depends on which you measure:
By this metric, Gartner's prediction is clearly not on track. Google has not disclosed an absolute decline and third-party estimates continue to put daily queries above 8.5 billion — consistent with or slightly ahead of 2024 levels. The raw count simply hasn't dropped 25%.
By this metric, the prediction is on track or ahead. Multiple Q4 2025 and Q1 2026 studies — from Ahrefs, Semrush, and independent SEO researchers — show that on queries where AI Overviews appear, click-through to publisher sites is down 30–50% compared to pre-AI-Overview baselines. Users are getting their answer from Google without leaving Google. Functionally, that query has moved away from "traditional search behavior" even though Google counted it as a query.
By this metric, search-intent behavior is growing, not shrinking. More people are asking more questions to more engines than ever. But the distribution is spreading: an estimated 10–15% of informational queries now go to ChatGPT, Perplexity, Gemini app, DeepSeek, and Claude instead of any form of Google. That is the share that has moved in the direction Gartner predicted.
Pulling together vendor disclosures, Similarweb traffic panels, and public SEO industry studies, here is the Q1 2026 picture:
Gartner was right about the direction. They were slightly early on the magnitude if you measure by raw Google queries, and slightly late if you measure by publisher traffic compression. On the net effect for SaaS marketing sites trying to win organic search traffic, they were right on the money.
The practical implication for SaaS founders is identical whether the prediction was exactly right or only directionally right: the organic-search-to-SaaS-marketing-site flow that worked from 2010–2023 is materially smaller in 2026. The total addressable audience is bigger than ever — it has just fragmented across Google, ChatGPT, Perplexity, Gemini, DeepSeek, and Claude.
If you haven't already adjusted:
If you want the diagnostic part done for you, EurekaNav runs a one-shot audit across all six engines and returns a prioritized fix list with the underlying evidence (actual AI answers) attached. That is the minimum viable first step for any SaaS that cares about being found in 2026.
Gartner's original 2024 research note is the anchor for this post. Q1 2026 Google / Bing / AI Overview deployment figures are drawn from publicly available Ahrefs, Semrush, and SparkToro studies; vendor disclosures (OpenAI, Perplexity, Anthropic blog posts); and Similarweb traffic-panel data. Publisher-traffic compression figures are from Ahrefs and Semrush post-AI-Overview studies published Q4 2025 and Q1 2026. All figures are best-effort aggregations and should be read as directional rather than exact.
