ChatGPT Tops Google Paid-Click Rankings: What 13B Searches Reveal

A study by iPullRank covering 13.1 billion Google search events from 9.1 million opted-in users found that ChatGPT draws a larger share of paid clicks from Google than any other major destination analysed, including YouTube, Reddit, and Facebook. The data spans October 2024 through December 2025 and shows that OpenAI is not relying on organic or direct traffic alone. Paid search is actively moving users from Google to ChatGPT, reshaping how advertisers should think about the Google-versus-AI narrative.

What happened

Metric	Finding
Dataset size	13.1 billion search events, 9.1 million opted-in users
Study period	October 2024 to December 2025 (15 months)
ChatGPT overall rank	6th most-clicked destination from Google
ChatGPT paid-click share	Highest proportion among all top destinations studied
Zero-click rate change	Up ~2.6 percentage points over the study period
Organic click share change	Down ~2.8 percentage points
Paid click share change	No meaningful change
ChatGPT zero-click intercept rate	11.1% (one of the lowest of major destinations)
Paid click rate on branded searches	4.4% vs 3.3% for non-branded
Discovery clicks (destination not named in query)	~86% of all Google clicks

iPullRank’s dataset places ChatGPT just outside the top five Google click destinations, behind YouTube, Google’s own properties, Reddit, Facebook, and Wikipedia. That ranking alone is notable. What’s more striking is the paid-click composition: ChatGPT’s share of clicks that came via paid ads was higher than any other leading destination in the study.

That tells us OpenAI is buying Google traffic, not just earning it. Whether through defensive brand bidding or broader keyword targeting, paid search is part of how ChatGPT grows.

Why is ChatGPT hard for Google to neutralise?

According to iPullRank, only 11.1% of searches that would have led to ChatGPT were intercepted by a zero-click experience on Google. That is one of the lowest interception rates of any major destination studied. The reason is mostly intent: a large share of ChatGPT searches are navigational. A user typing “ChatGPT” into Google wants to open the product, not read a fact box about it. Google can answer a question in place; it cannot replace the destination.

This is the same dynamic that has historically protected brand searches. And the data backs that up: when branded searches resulted in a click, 4.4% of those clicks were paid, versus 3.3% for non-branded queries. Brands, including OpenAI, pay to defend their own name in results.

What the zero-click trend actually means for paid search

The broader zero-click story is often framed as bad news for the whole channel. This data complicates that. Google’s zero-click rate rose roughly 2.6 percentage points over the 15-month window and organic click share dropped about 2.8 points. Paid click share, however, showed no meaningful change across the same period.

In other words, AI Overviews and other zero-click features appear to be eating organic traffic, not ad traffic. For businesses running Google Ads campaigns, this is a meaningful distinction: the threat is to unpaid visibility, not to ad real estate.

That said, one dataset is not a guarantee. Search behaviour is shifting fast, and a 15-month window ending in late 2025 may not capture what happens next.

86% of clicks go to destinations users didn’t name

One underreported finding: only about 14% of Google clicks landed on a site the user had explicitly named in their query. The remaining 86% were discovery clicks, where Google directed users somewhere they had not specifically requested. For advertisers, that is a significant pool of contestable attention where ads, rankings, and search features can introduce users to a brand for the first time.

This challenges the idea that Google is purely a demand-capture tool. The data suggests it still generates demand, and that paid placement within that 86% slice remains valuable. If you are working on organic search strategy alongside paid, the split between navigational and discovery intent should inform how you allocate budget.

Our take

The headline finding, that ChatGPT draws the highest paid-click proportion of any major Google destination, should reframe how brands think about the Google-versus-AI debate. These are not separate ecosystems. Users are moving from Google to ChatGPT via ads, which means OpenAI is actively competing for paid attention inside Google’s own platform.

For most businesses, the immediate takeaway is defensive: if you have a recognisable brand, the 4.4% paid rate on branded queries is a reminder that competitors (or, in OpenAI’s case, a category disruptor) can intercept your traffic with a well-placed ad. Own your brand terms.

The paid-click stability finding is genuinely reassuring, but we would not treat it as a ceiling. Google’s incentives to preserve ad revenue are strong, which partly explains why zero-click growth has targeted organic results rather than ads so far. That alignment of incentives may not hold forever. Watch the trend quarterly, not annually.

Practical takeaway: Treat paid search as complementary to AI discovery, not a fallback for it. The data shows users travelling from Google to ChatGPT via ads. Your brand could be on that same journey, in either direction.
