TL;DR: Between 2023 and 2025, HubSpot lost 75% of its organic web traffic. The SEO world panicked, calling it the death of content marketing. But they missed the punchline: while traffic cratered, HubSpot’s revenue grew by 22%. Why? Because they stopped playing the Google Click game and started dominating the AI Citation game. They lost millions of useless top-of-funnel clicks, but gained a 35% "share of voice" in LLMs, where visitors convert at 23x the rate of traditional search.

The SEO industry has been crying over a chart that shows HubSpot’s monthly organic traffic plummeting from 24.4 million visits down to just 6.1 million between 2023 and 2025.
Pundits called it a collapse. A cautionary tale. But if you look at the actual business metrics, it wasn't a collapse at all. It was a highly successful, accidental transition into the new era of AI Search.
HubSpot's CEO recently said it out loud on an earnings call: "Organic search traffic is declining globally... our new goal is to be cited in LLMs more than any other competitor." The company that literally invented the inbound marketing/SEO empire just told the world: Citations are the new rankings. Here is the data that will permanently change how you view your website's traffic.
1. The Death of the Vanity Metric
Why did HubSpot lose 18 million monthly visitors? Because 91.3% of queries triggering AI Overviews are informational.
HubSpot built its massive traffic empire on top-of-funnel informational content:
- "How to write a cover letter"
- "Famous quotes about success"
- "What is a sales funnel"
This is perfect AI fodder. ChatGPT and Google's AI Overviews simply absorbed this information, answered the user directly, and stopped sending traffic to the website. Today, 60% of Google searches end without a single click, and AI Overviews appear on 27% of all queries.
But here is the brutal truth: Most of those 24 million visitors were never going to buy CRM software. Someone searching "how to write a resignation letter" is not your target B2B buyer. AI didn't destroy HubSpot's pipeline; it destroyed a vanity metric masquerading as a pipeline.
2. The New Conversion Math (Citations > Clicks)
What replaced that massive wave of useless traffic? The high-intent buyer.
Today, a Director of Sales opens ChatGPT or Perplexity and asks: "What is the best CRM for a 50-person B2B sales team, HubSpot or Salesforce?"
HubSpot holds a 35.3% share of voice in AI-generated answers for their category. They are in the answer, almost every single time. And the conversion math on these AI-referred visitors is staggering:
- AI search visitors convert 23x better than traditional organic traffic.
- AI-referred traffic carries a 4.4x higher economic value.
When a buyer clicks through from an LLM, they arrive already sold. They have already compared features, and they already trust the brand the AI recommended. This is exactly why HubSpot's traffic dropped 75%, but their revenue went up 22% in Q4 2024.
3. The Content That Kills You vs. The Content That Saves You
If you are still building top-of-funnel informational content in 2026, you are building on a sinking foundation. You must stop publishing content AI can replace, and start publishing content AI has to cite.
Content AI Replaces (Do Not Write This):
- General definitions ("What is a sales funnel?")
- Broad best practices ("10 tips for email marketing")
- Generic how-to guides.
Content AI MUST Cite (Double Down on This):
- Original Research: "We analyzed 50,000 email campaigns sent through our platform; here is the proprietary open-rate data." AI cannot hallucinate proprietary data; it must attribute it to you.
- Proprietary Benchmarks: Data that only your specific platform generates.
- Opinionated Frameworks: Unique strategic methodologies that carry your brand name.
HubSpot audited over 13,000 URLs and aggressively pruned or rewrote 60% of them. They shifted from broad definitions to product-adjacent depth.
Conclusion: The Mercury Perspective
At Mercury Technology Solutions, we have been running this exact same transition. We stopped chasing traditional blog rankings and shifted entirely to engineering our AI citation coverage. Today, roughly 20% of our inbound revenue comes from AI-referred leads. They close faster, and they show up to the sales call already knowing exactly what we do.
Traffic is a lagging indicator of a 2023 strategy. AI share of voice is the leading indicator for 2026 and beyond.
