Is your website optimised for AIO / GEO?
Website traffic is declining as AI search and AI-generated summaries begin to replace traditional clicks. Rather than navigating multiple sites, users increasingly receive complete answers directly within the search interface, reducing the need to visit external websites.
Research from multiple independent sources indicates that zero‑click searches have risen significantly, with around 27% of all searches ending without any click to an external site in 2025, and other independent data indicating rates as high as 60‑70% of searches might now end without any click at all.
This is not a temporary fluctuation. It represents a structural shift in how information is discovered, evaluated, and delivered. The rapid adoption of AI assistants and AI search interfaces has given rise to new disciplines aimed at ensuring organisations remain visible when answers are generated, rather than merely linked.
How do you respond to this dramatic shift in discoverability?
Two terms that are becoming increasingly relevant are AIO (AI Optimisation) and GEO (Generative Engine Optimisation). Both respond to this structural change, but at slightly different levels.
This marks a departure from traditional SEO. With SEO, success was measured by visibility in search results, particularly on platforms such as Google, and by earning clicks. In contrast, GEO requires that your content become part of the answer itself, directly integrated into AI-generated responses.
"Traditional search was built on links. GEO is built on language. It’s no longer about Click-Through-Rates. It is about reference rates: How often your brand is cited in model generated answers".

Introducing S1xSIGNALS a simple framework for AIO and GEO
The S1xSIGNALS framework was created by 1xINTERNET to help organisations navigate the shift from traditional web traffic to AI-driven content discovery. In a landscape where answers are delivered directly by AI systems, content must do more than exist, it must be structured, credible, and immediately usable.
S1xSIGNALS evaluates content across six critical dimensions: Citation Readiness, Query Alignment, Content Structure and Formatting, Authority and Trust Signals, Semantic Clarity and Entity Recognition, and Technical Accessibility. Each dimension targets a key factor in ensuring that your content can be recognised, trusted, and cited by AI systems.
