Direct answer
What share of B2B SaaS homepages use WebSite schema?
In Growthract's 2026 AI Search Readiness Benchmark, only 39 of 97 inspectable B2B SaaS homepages (40.2%) had WebSite schema present, even though 72.2% had Organization schema — making WebSite the most commonly skipped of the core identity schema types in this sample.
01
WebSite schema trails Organization schema by roughly 32 percentage points in this sample, despite both being simple, low-effort additions.
02
WebSite schema is what lets a stable Organization @id and a site-level identity connect explicitly — skipping it leaves that link implicit.
03
This is a homepage-only, presence-only check; it doesn't evaluate whether the WebSite schema present was implemented correctly.
Of the four core identity and content schema types we checked, WebSite schema had the biggest adoption gap relative to its closest sibling type.
40.2%
of inspectable B2B SaaS homepages carried WebSite schema
Compare that to Organization schema, present on 72.2% of the same homepages — a 32-point gap between two schema types that are roughly equally simple to implement.
Why WebSite schema specifically lags
Most schema-implementation guides — including our own — lead with Organization schema, since it describes the company itself. WebSite schema, which formally connects a domain to that organization as its publisher, often reads as an optional follow-up step rather than a required companion.
In practice, the two are meant to work together: a stable Organization @id that WebSite schema references as its publisher, rather than two disconnected objects.
The copy-paste pattern for both, including how the @id reference works, is in Schema Markup for AEO: A Copy-Paste Implementation Guide.
What WebSite schema actually adds
Google uses WebSite structured data as one input for site-name preferences in search results, and it formally establishes the domain-to-publisher relationship that individual Article or Product schema on other pages can reference back to.

FAQs
Is WebSite schema less important than Organization schema?
They serve different, complementary purposes — Organization describes the company, WebSite describes the site and its publisher relationship. Neither is optional if you want a complete identity layer.
Does adding WebSite schema improve rankings?
There's no evidence it directly affects ranking. It clarifies machine-readable identity, which is a different, narrower claim than a ranking guarantee.
