The 51 Percent AI-Buyer Stat Has No Named Study. The 32 Percent CTR Drop Does.
Neil Patel's SaaS SEO guide states both. Only one of them is safe to put in a deck, and it is not the headline number.

Neil Patel's SaaS SEO guide, published August 7, puts a number on something GEO practitioners have long argued from anecdote: 51 percent of B2B software buyers now start their research with an AI chatbot more often than Google.
The guide does not name a study behind that figure. It appears in the piece's own key takeaways, stated as fact without citation. Treat it as Patel's own reporting. If it goes into a sales deck, flag that there is no named study behind it.
The mechanism behind the number
What the guide does source is why buyers are moving. GrowthSRC data, cited directly, shows Google's average click-through rate for the No. 1 ranking position dropped 32 percent year-over-year, from 28 percent in 2024 to 19 percent in 2025, after the AI Overviews rollout.
That is the more useful figure for a SaaS marketing team. Even the best-ranked result on the page is earning fewer clicks, because the AI Overview above it has often already answered the question. Read together, the two stats describe one shift from two sides: buyers open a chatbot first, and the ones who do still search are clicking less once they land. A team watching only its position-one rankings will see the dashboard hold steady while the traffic underneath drains out.
What still works, per the guide
Patel's advice does not throw out the fundamentals: keyword research, on-page SEO, and link building are all still in the playbook. What changes is the bar. Content now has to rank in the SERP and earn a citation inside the AI answer, and the guide treats those as different jobs. The content that gets pulled into AI answers carries a first-hand point of view: original testing, original data, an argument the page actually makes.
The guide's other headline number, a 702 percent ROI on SaaS SEO spend, has the same sourcing gap as the 51 percent figure. It is introduced as "recent data" with no named source behind it. We are leaving it out of the datapoints below for that reason.
