NOTABIS SEO / LEARN
Practical guides for the SEO findings NOTABIS measures. Learn what an issue means, how to verify it, when it is intentional, and how to fix it safely.
Performance · 9 Sep 2026
Cache-Control tells clients and intermediaries how a response may be stored. Missing policy is a configuration review, not proof that a page is slow or that one universal cache setting is safe.

A meta description should accurately summarise the page in useful language. Length warnings are review signals because display truncation varies; there is no universal character limit that guarantees a particular snippet.
Read guide →Accessibility · 9 Sep 2026
A main landmark identifies the dominant content region of a document. Add one meaningful main region to content pages, while recognising that the best structure depends on the document and accessibility needs.

An H1 is a page’s primary visible heading. NOTABIS reports a missing H1 when none is measured in the crawled document; the right fix is to provide a useful page heading, not to add an H1 mechanically to private or non-content responses.

Multiple URLs can contain substantially similar or identical material without all being wrong. First decide whether the URLs are intended standalone pages, variants, or accidental duplicates; then choose canonicalisation, consolidation, or genuinely distinct content.

JSON-LD is structured data embedded in a page as JSON. NOTABIS reports invalid JSON when the structured-data payload cannot be parsed as valid JSON.

A canonical/noindex conflict is a page that declares a canonical URL while also sending a noindex directive. That combination should be deliberate and understood.

A canonical link element identifies the preferred URL for a page when similar or alternate URLs exist. NOTABIS reports when no canonical is measured.

A redirect chain occurs when a requested URL follows multiple redirects before reaching its final response. NOTABIS reports the measured chain, not a ranking guarantee.

Duplicate meta descriptions mean multiple URLs share the same description text. This is a review signal, not automatic proof that every URL is wrong.
Read guide →Metadata · 8 Sep 2026
Duplicate title metadata means multiple URLs share the same title text. The correct response depends on whether those URLs are standalone indexable pages or intentional variants.
Read guide →Links · 8 Sep 2026
A broken internal link is a link on one crawled page whose internal target returns an error. It is a link problem, not merely a spelling or styling issue.

A meta description is page-level text that can help describe a URL in search results. NOTABIS reports this when no controlled search snippet description is measured.

A title element is the page title exposed to browsers and search systems. NOTABIS reports this when no title element is measured; it does not judge whether an existing title is persuasive.

An HTTP error response is a server response that tells a browser or crawler a request could not be completed normally.
