The NOTABIS score is a directional diagnostic built from measured issue density, not a Google score or ranking prediction.

Canonical tags identify a preferred URL among similar variants. NOTABIS checks presence, duplicates, origin, redirects, noindex conflicts, and duplicate content as separate signals.
Read guide →Structured data · 16 Sep 2026
Structured data gives machines context about visible page content. NOTABIS separates JSON syntax and format presence from vocabulary validity and search-feature eligibility.

Core Web Vitals measure user-facing performance outcomes, while markup heuristics identify patterns worth investigating. NOTABIS labels render-blocking and related signals as review evidence, not measured vitals.
Read guide →Links · 16 Sep 2026
Internal links connect pages on the same site and help users and crawlers discover relationships. NOTABIS measures link status, inbound evidence, and crawl depth from the HTML it can crawl.

A broken link describes an unusable path from a source page, while an HTTP error describes the response returned for a request. NOTABIS records both as separate evidence.
Read guide →Images · 16 Sep 2026
Good image SEO combines useful context, accurate alt text, stable dimensions, responsive delivery, and sensible formats. NOTABIS measures these concerns separately so fixes can be prioritised safely.

Authentication redirects protect private routes but can hide public pages when middleware is too broad. NOTABIS records final URLs and page context so private intent can be separated from accidental redirects.

Different URLs can serve the same or similar content through parameters, old routes, print views, or tracking. Align canonical, redirect, link, and sitemap signals around each variant’s intended purpose.

An XML sitemap lists public URLs or child sitemaps to support discovery. NOTABIS validates access, XML structure, headers, namespaces, and URL reconciliation without treating a sitemap as an indexing guarantee.

Robots.txt controls crawler access, while noindex tells a crawler that it may fetch a page but should not include it in search. They are different controls for different goals.

NOTABIS records rdfa-present when measured HTML contains typeof or property attributes. Presence is not proof that the RDFa vocabulary or values are valid.
Read guide →Structured data · 16 Sep 2026
NOTABIS records microdata-present when measured HTML contains an itemscope element. The check confirms presence only; it does not validate schema vocabulary, properties, or rich-result eligibility.
