Technical SEO checks built into every scan.

Checks every page for the SEO basics that search engines care about — missing titles, broken schema, thin descriptions.

What it checks

Meta title and description presence, length, and uniqueness
Heading hierarchy validation (H1 presence, nesting order)
Image alt text coverage
Canonical tag presence and self-referencing checks
Open Graph and Twitter Card validation
Product schema field completeness (name, description, image, price, brand, SKU)
Basic hreflang validation (missing tags, missing x-default)
Structured data presence detection
robots.txt accessibility check

What you don't know

Missing titles. Broken schema. Thin descriptions. On every page you forgot to check.

SEO issues don't announce themselves. A missing meta description. A product page without schema markup. An H1 tag that's actually an H3. Search engines see all of it — and rank you accordingly.

Cassian runs 23 deterministic HTML checks on every page, every scan. No AI cost, no variability. The same checks, consistently applied, across your entire store.

How Cassian™ detects this

Every scan runs 23 deterministic checks via HTML parsing. These are free, instant (~2ms/page), and don’t use AI — they’re structural validation. Checks include: meta title/description presence and length, heading hierarchy (H1 presence, nesting), alt text coverage, canonical tag correctness, Open Graph and Twitter Card validation, favicon, mixed content, robots meta tag, structured data presence, Product schema field completeness (name, description, image, price, brand, SKU/GTIN), product page content and image validation, and basic hreflang validation for multilingual stores.
