In 2025, discoverability is no longer ‘SEO vs product’. It’s exposure posture - what the open web can see, what AI can cite, and what users can access without friction.
DSHI is a measured cohort; it does not represent all portals globally. See Methodology for coverage and evidence rules.
The most important finding in DSHI is not who is ‘#1’. It is the distribution shape.
A mid-heavy distribution implies that marginal gains are difficult: most portals are competing on similar exposure foundations, so small posture changes (crawlability, canonical hygiene, gating) can shift outcomes disproportionately.
GPPI uses banding to keep interpretation board-safe: Strong (≥60) indicates robust exposure infrastructure; Watch (<40) indicates structural constraints.
In the 2025 DSHI cohort (n=58 portals), the median Discoverability score is 44.8/100 (IQR 37.3–52.2). 12.1% of measured portals fall in the Strong band (≥60).

A portal can be ‘Strong’ in discoverability without being the biggest brand. Conversely, a large brand can be constrained by posture (gating) even if it has authority.
2025 makes a new tradeoff explicit: portals are deciding what to expose to the open web.
Open indexability can support reach and AI citations, but it can also increase scraping, spam, and competitive intelligence risks. Gating can improve conversion control, but it reduces surface area for discovery.
GPPI’s indexability posture classification is designed to make this tradeoff visible without implying intent or wrongdoing.
Across the same DSHI cohort (n=58), only 19.0% present an Open indexability posture, while 46.6% are Mixed and 12.1% are Gated/Restricted. 22.4% could not be classified with sufficient evidence.

In 2025, discovery happens in at least three places:
• Traditional search engines (SEO/SEM)
• In-product discovery (search, ranking, recommendations)
• AI-mediated discovery (assistants and answer engines that cite or summarise sources)
This means discoverability isn’t only about traffic - it’s about representation. If an AI assistant summarises inventory incorrectly or routes users away, the portal needs governance visibility and evidence trails (link: AI Adoption Signals).
Discoverability and trust are now coupled: exposure concentrates scrutiny.
