Schema Markup Adoption Across the Top 1,000 SaaS Sites (2026 Benchmark)

What I personally did

• Designed the research question and the sampling method.
• Collected and graded the data personally — no outsourced or scraped third-party dataset.
• Wrote every word of the published piece and maintain it after publication.

How the numbers were measured

1. Homepages and primary pillar pages crawled, JSON-LD parsed programmatically, and schema types counted per site.
2. Validation errors recorded separately from absence of markup — a broken block is not the same as no block.

Evidence you can check
