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.
Images · 9 Sep 2026
Give informative images useful alternative text and mark decorative images with an empty alt attribute. Missing alt text is primarily an accessibility problem; the correct wording depends on the image’s purpose.

Multiple H1 elements are not automatically an SEO failure, but they can indicate unclear document structure or an accidental template duplicate. Review the visible hierarchy and page purpose before changing them.

Title length is a review signal, not a magic ranking threshold. Write a concise title that identifies the page, puts important context early, and remains accurate when truncated.

NOTABIS flags img elements missing a width or height attribute. Add accurate intrinsic dimensions; CSS aspect-ratio can reserve space but does not satisfy this markup check.
Read guide →Links · 9 Sep 2026
No crawled internal HTML page links to this URL. Check whether a sitemap or another source discovered it, then decide whether useful contextual links are missing.

Security headers deserve a security review, but their absence in an SEO crawl is not a complete vulnerability assessment. Configure them with the application’s actual resource, embedding, and privacy requirements.

Social metadata helps sharing systems understand a page preview. Missing fields are an interoperability review and do not prove that every social platform will display a broken card.
Read guide →Performance · 9 Sep 2026
A render-blocking finding identifies markup patterns that may delay first rendering. It is a candidate list, not measured proof of user-visible impact; validate changes with performance evidence.

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.
Read guide →Metadata · 9 Sep 2026
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> element marks the dominant content region. NOTABIS checks for that element; an ARIA main role alone does not pass this rule.
Read guide →Content · 9 Sep 2026
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.
Read guide →Structured data · 8 Sep 2026
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.
Read guide →Crawlability · 8 Sep 2026
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.
