AEO

GEO has found its place in the search landscape, and it’s reasonable to think that the future of generative engine optimization is guaranteed. According to Datos’s State of Search report, Q4-2025 saw some interesting changes. For the first time, AI tools had a consistent 1.31% to 1.34% of visits in the U.S. In previous quarters and reports, traffic to AI tools was growing. This stability in traffic suggests that AI search tools may have found their place in the wider search landscape.

Today, more and more buyers are beginning their journey with an AI-search. They may ask ChatGPT to compare products or use an AI-powered platform like Perplexity. Or, they’re just Googling an offering and reading the AI Overview, all without clicking a link. 

HubSpot realized that our buyers were moving from search engines to answer engines like ChatGPT, Gemini, and Perplexity — but we had no reliable way to measure AI visibility and understand whether our AEO plays were working.

Most marketing teams I talk to are doing genuinely good SEO, and yet when they open ChatGPT or Perplexity and type in the prompts their buyers are actually using, their brand is nowhere to be found. This is the exact problem the FSA Framework was built to solve.

An AEO strategy for SaaS won’t stray too far away from a good SEO strategy, but some tactics benefit AI search more than others, and it helps to know what these are. We all know that AI has shifted how brands earn visibility, and how visibility doesn’t equal clicks. But for SaaS, the way buyers conduct discovery and evaluation has changed disproportionately.

AI-referred traffic has increased by 600% since January 2025, and marketers are racing to understand what that means for brand discovery. For teams seeking clarity on how AI impacts brand and pipeline means investing in new tools like Profound or Athena AI for Answer Engine Optimization (AEO).

AI search is already influencing how buyers discover brands — and the results are measurable. According to the 2026 HubSpot State of Marketing report, 58% of marketers say visitors referred by AI tools convert at higher rates than traditional organic traffic. As platforms like ChatGPT, Perplexity, and Gemini increasingly shape buying decisions, visibility inside AI-generated answers is quickly becoming a competitive advantage.

Artificial intelligence (AI) is rewriting the playbook of so much of our lives — how we interact, how we learn, how we complete daily tasks, and sometimes even what we eat for dinner. So, of course, AI and the future of SEO are no different.
