This artifact records the observable convergence between Google’s February 2026 Discover core update and the AI Visibility framework published weeks prior.

The Platform Signal

On February 5, 2026, Google released a Discover core update with explicit implementation language:

“Since many sites demonstrate deep knowledge across a wide range of subjects, our systems are designed to identify expertise on a topic-by-topic basis.”

The update specified three corrective actions:

Reducing sensational content and clickbait
Showing more in-depth, original, and timely content from websites with expertise in a given area
Showing users more locally relevant content from websites based in their country

Google provided a concrete example:

“For example, a local news site with a dedicated gardening section could have established expertise in gardening, even though it covers many topics. In contrast, a movie review site that wrote a single article about gardening would likely not.”

The Prior Framework

The AI Visibility framework published December 2025 through January 2026 predicted this exact shift.

Volume to Depth

Framework statement (December 3, 2025):

“Visibility will move away from reach and volume and toward structure, clarity, and verifiability. Signal quality will matter more than output.”

Google implementation:
Topic-by-topic expertise evaluation replacing broad authority signals.

Bloat Reduction

Framework statement (December 3, 2025):

“Bloat leads to signal deprecation, ambiguity, and fragmentation. It is a significant contributor to AI hallucinations.”

Google implementation:
Explicit reduction of sensational content and clickbait.

Verification Over Social Proof

Framework statement (December 18, 2025):

“The Role of Social Proof: Google reinforced this model by treating social engagement as a proxy for credibility and relevance. As the technology evolves, those signals may carry less weight.”

Google implementation:
Demonstrated expertise through content depth rather than engagement metrics.

Structural Clarity

Framework statement (January 2, 2026):

“AI Visibility refers to the intentional design of digital assets such that their informational content produces clear, stable, and machine interpretable signals.”

Google implementation:
Systems designed to understand a site’s content for expertise evaluation.

Timeline

December 3, 2025: AI Visibility warning published
December 18, 2025: EEAT measurement critique published
January 2, 2026: AI Visibility canonical definition published
January 14, 2026: Shallow Pass Selection Hypothesis published
February 5, 2026: Google Discover update released

Observed Pattern

Platform behavior converged with upstream ingestion theory within weeks of formal publication.

The gardening example Google provided matches the framework’s distinction between demonstrated topic expertise and isolated content production.

The emphasis on “our systems’ understanding of a site’s content” reflects structural evaluation rather than surface-level metrics.

Classification

This artifact does not claim predictive causation. It records temporal and structural alignment between independently published theory and subsequent platform implementation.

The convergence occurred across multiple signal types: content depth evaluation, topic-specific expertise, bloat reduction, and verification mechanisms.
