Document metadata

SEO-DESCRIPTION-001Official platform recommendation · RecommendedMeta description is presentDocumentWarning when failedWeight 1Technical Search

What this checks: Whether the returned HTML declares a meta description.
Why it matters: Google sometimes uses the meta description for the search snippet when it describes the page more accurately than on-page text, and recommends page-level descriptions, prioritizing important pages.
How to fix: Add a <meta name="description" content="..."> that accurately summarizes this specific page.

Expected: The page declares <meta name="description"> with a page-specific summary.
Applies to: Every retrieved page.
Authority: Official platform recommendation · RecommendedGoogle Search recommendation for snippets; not required for indexing.
Technical Score: Weight 1 of 3Google uses the meta description only sometimes for snippets. Missing and empty descriptions are mutually exclusive checks with the same weight.
How MaxiMarket detects it: Reports when no meta element named description is found in the returned HTML.
Sources: Control your snippets in search results — Google Search Central, verified 2026-09-26

SEO-DESCRIPTION-002Official platform recommendation · RecommendedMeta description is not emptyDocumentWarning when failedWeight 1Technical Search

What this checks: Whether the first meta description has content.
Why it matters: An empty description cannot serve as a snippet source, so it provides none of the benefit Google describes for meta descriptions.
How to fix: Fill the content attribute with an accurate summary of the page, or remove the empty tag.

Expected: The meta description content attribute contains a page-specific summary.
Applies to: Pages with a meta description.
Authority: Official platform recommendation · RecommendedGoogle Search recommendation for snippets; not required for indexing.
Technical Score: Weight 1 of 3Same weight as a missing description; only one of SEO-DESCRIPTION-001 and -002 can apply.
How MaxiMarket detects it: Reports when the first meta description is present but its content is empty after whitespace normalization.

Canonicalization

SEO-CANONICAL-001Official platform recommendation · RecommendedCanonical URL is declaredDocumentWarning when failedWeight 1Technical SearchAI Discovery

What this checks: Whether the returned HTML declares a rel="canonical" link.
Why it matters: Google treats rel="canonical" as a strong canonicalization signal. Declaring one is optional: without it, Google selects a canonical URL itself.
How to fix: Add <link rel="canonical" href="..."> with the absolute preferred URL of this page.

Expected: The page declares a <link rel="canonical"> pointing to its preferred URL.
Applies to: Every retrieved page.
Authority: Official platform recommendation · RecommendedGoogle encourages canonical declarations but states that none of the methods are required.
Technical Score: Weight 1 of 3Google treats an explicit canonical as optional; declaring one is a helpful signal.
How MaxiMarket detects it: Reports when the returned HTML has no link element whose rel includes canonical, or the first such link has an empty href. The target is neither validated nor fetched.

RFC 6596: The Canonical Link Relation — IETF, verified 2026-09-26

SEO-CANONICAL-004Official platform recommendation · RecommendedCanonical URL is absoluteDocumentInfo when failedNot scoredTechnical SearchAI Discovery

What this checks: Whether the declared canonical href is an absolute URL.
Why it matters: Google recommends absolute rather than relative paths for rel="canonical". RFC 6596 allows relative references, so a relative canonical is not invalid.
How to fix: Use the full URL, such as https://www.example.com/page, in the canonical link.

Expected: The canonical link uses an absolute URL, including the scheme.
Applies to: Pages that declare a non-empty canonical URL.
Authority: Official platform recommendation · RecommendedGoogle canonicalization recommendation; relative canonicals are valid under RFC 6596.
Technical Score: Not scoredRelative canonicals are valid under RFC 6596 and resolve correctly; Google's preference for absolute URLs is advisory only.
How MaxiMarket detects it: Reports when the first canonical href does not start with a URL scheme (for example /page, page or //host/page).

SEO-CANONICAL-005Official platform recommendation · RecommendedCanonical URL has no fragmentDocumentWarning when failedWeight 1Technical SearchAI Discovery

What this checks: Whether the declared canonical URL includes a fragment.
Why it matters: Google advises against specifying URL fragments as canonical URLs.
How to fix: Remove the #fragment from the canonical URL.

Expected: The canonical URL has no #fragment.
Applies to: Pages that declare a non-empty canonical URL.
Authority: Official platform recommendation · RecommendedGoogle canonicalization recommendation.
Technical Score: Weight 1 of 3Google advises against fragment canonicals; the fragment is normally dropped, so the effect is limited.
How MaxiMarket detects it: Reports when the first canonical href contains a # character.

SEO-CANONICAL-008Official platform recommendation · RecommendedCanonical signals agree across methodsDocumentWarning when failedWeight 2Technical SearchAI Discovery

What this checks: Whether the canonical in the HTTP Link header and in the HTML link element point to the same URL.
Why it matters: Google asks not to specify different canonical URLs through different techniques.
How to fix: Declare the same canonical URL in the Link header and the link element, or use only one method.

Expected: The same canonical URL in every method.
Applies to: Pages that declare a canonical both in an HTTP Link header and in a link element.
Authority: Official platform recommendation · RecommendedGoogle canonicalization recommendation.
Technical Score: Weight 2 of 3Conflicting canonicals across methods may make search engines ignore both.
How MaxiMarket detects it: Resolves the first canonical Link header entry and the first canonical link element against the final URL, ignoring fragments, and reports when they differ. Sitemap inclusion is not compared.

HTTP and retrieval

HTTP-HTTPS-001Official platform recommendation · RecommendedPage is served over HTTPSDocumentWarning when failedWeight 2Technical Search

What this checks: The scheme of the final URL.
Why it matters: Google lists secure (HTTPS) serving among page-experience considerations.
How to fix: Serve the page over HTTPS and redirect the HTTP version to it.

Expected: https.
Applies to: Every retrieved page.
Authority: Official platform recommendation · RecommendedGoogle Search page-experience consideration; not a requirement for indexing.
Technical Score: Weight 2 of 3Secure serving is a stated page-experience consideration and affects every visitor, but it does not block indexing.
How MaxiMarket detects it: Reports when the final URL of an available page uses http rather than https.

HTTP-REDIRECT-003Official platform recommendation · RecommendedProtocol and host normalization redirects are permanentIndexingWarning when failedWeight 1Technical SearchAI Discovery

What this checks: The status of each redirect on the way to the final URL that changes only the scheme and/or a leading "www." host label.
Why it matters: Google recommends permanent server-side redirects for permanent moves, and treats permanent redirects as a strong canonical signal. Moving to HTTPS or to the preferred host variant is permanent.
How to fix: Answer requests for the other scheme or host variant with a 301 or 308 redirect to the preferred URL.

Expected: Such redirects use 301 or 308.
Applies to: Audited URLs whose redirect chain includes a hop that changes only the scheme and/or a leading "www." host label, keeping path and query; other pages are not applicable.
Authority: Official platform recommendation · RecommendedGoogle redirect recommendation.
Technical Score: Weight 1 of 3A temporary normalization redirect weakens a canonical signal; the page is still reached.
How MaxiMarket detects it: Inspects the redirect hops the fetch followed (up to 5). A hop is a normalization redirect when path and query stay the same and only the scheme changes and/or the host gains or loses a leading "www." label. Reports when such a hop answers 302, 303 or 307. In browser audits the hops come from the navigation's redirect chain.

HTTP-REDIRECT-004Official platform recommendation · RecommendedPage does not redirect with meta refreshIndexingWarning when failedWeight 1Technical SearchAI Discovery

What this checks: Whether the page declares <meta http-equiv="refresh"> with a URL of another page.
Why it matters: Google recommends server-side redirects; a meta refresh redirect is only seen when the page is retrieved and parsed, and other consumers may not follow it.
How to fix: Replace the meta refresh with a server-side 301 or 308 redirect.

Expected: Redirects are server-side (HTTP 301 or 308 for permanent moves).
Applies to: Every retrieved (available) page.
Authority: Official platform recommendation · RecommendedGoogle redirect recommendation.
Technical Score: Weight 1 of 3A meta refresh still redirects; it is a weaker, slower signal than a server-side redirect.
How MaxiMarket detects it: Reports when a meta http-equiv="refresh" element has a url= value that resolves to a different URL than the page (ignoring fragments). A refresh without a URL (a reload) passes. JavaScript redirects are not detected: they cannot be observed without executing scripts.

Links and discoverability

LINK-IMAGE-ALT-001Official platform recommendation · RecommendedImage links have alt textDocumentWarning when failedWeight 1Technical SearchAI DiscoveryMachine Readability

What this checks: Links whose only content is one or more images.
Why it matters: Google uses the alt text of a linked image as the link's anchor text, and WCAG requires that link purpose can be determined.
How to fix: Give the image inside the link an alt attribute that describes the link destination.

Expected: At least one image in such a link has non-empty alt text.
Applies to: Pages with at least one link whose only content is one or more images.
Authority: Official platform recommendation · RecommendedGoogle link recommendation (WCAG 2.4.4).
Technical Score: Weight 1 of 3Image links without alt text lose their anchor text. Excluded from the score when MEDIA-IMG-ALT-001 fails, because the same missing alt attribute would otherwise be penalized twice.
How MaxiMarket detects it: Reports when an a element with href contains no text and only img elements (optionally inside picture or plain wrappers), none of which has non-empty alt. Links with other content, such as SVG, are not applicable.

Images and media

MEDIA-IMG-SRC-001Official platform recommendation · RecommendedResponsive images keep a src fallbackDocumentWarning when failedWeight 1Technical Search

What this checks: img elements that declare srcset or a lazy-loading data attribute but no src.
Why it matters: Google finds images through img src and asks for a src fallback with srcset; images that only load through scripts may not be seen.
How to fix: Give every img a src attribute, even when srcset or a lazy-loading library is used.

Expected: Every such img has a src.
Applies to: Pages with at least one img element.
Authority: Official platform recommendation · RecommendedGoogle image recommendation.
Technical Score: Weight 1 of 3Images without a src fallback may not be discovered; the rest of the page is unaffected.
How MaxiMarket detects it: Reports when an img element has srcset, data-src or data-srcset but no non-empty src attribute. A placeholder src counts as present.

Indexing and snippet directives

INDEX-NOINDEX-CANONICAL-001Official platform recommendation · Recommendednoindex is not combined with a canonical URL pointing elsewhereIndexingWarning when failedNot scoredTechnical SearchAI Discovery

What this checks: Whether a page declares noindex for all crawlers and a canonical URL for a different page.
Why it matters: Google does not recommend using noindex to prevent selection of a canonical page within a single site; the two signals conflict.
How to fix: If this page duplicates another, keep the canonical URL and remove noindex. If the page should stay out of search, keep noindex and make the canonical point to the page itself or remove it.

Expected: The page uses one signal: a canonical URL pointing to the preferred page, or noindex.
Applies to: Pages that declare noindex for all crawlers and a non-empty canonical URL; indexable pages and crawler-specific noindex are not applicable.
Authority: Official platform recommendation · RecommendedGoogle canonicalization recommendation.
Technical Score: Not scoredDepends on noindex, an intent-dependent state that is itself not scored.
How MaxiMarket detects it: Reports when INDEX-NOINDEX-001 applies (noindex or none for all crawlers) and the declared canonical, resolved against the final URL and ignoring any fragment, is a different URL. Unparseable canonical values are not applicable.

What this checks: Organization structured data (or a subtype, such as OnlineStore) on the home page.
Why it matters: Google recommends Organization structured data on the home page (or an about page) to understand the organization behind the site.
How to fix: Add an Organization (or the most specific subtype) with name, url and logo to the home page.

Expected: At least one top-level Organization entity.
Applies to: Home pages (final URL path "/"); other pages are not applicable.
Authority: Official platform recommendation · RecommendedGoogle Organization structured data recommendation.
Technical Score: Weight 1 of 3Recommended on the home page to identify the organization.

How to fix: Add name, url and logo to the Organization.

Expected: All three present.
Applies to: Pages with at least one top-level Organization entity (Organization or a subtype).
Authority: Official platform recommendation · RecommendedGoogle Organization structured data recommendation.
Technical Score: Weight 1 of 3Recommended core identity properties; none is required.

What this checks: The format of datePublished and dateModified values.
Why it matters: Google asks for ISO 8601 dates and correct time zones; a time without a zone is ambiguous.
How to fix: Use values such as 2026-09-26 or 2026-09-26T08:00:00+02:00.

Expected: An ISO 8601 date, or a date and time with a time zone.

How MaxiMarket detects it: Compares ISO 8601 values with the audit time and with each other. A date without a time spans that whole day in every time zone, and a time without a zone spans all offsets, so only dates that are in the future (by more than one hour) or out of order under every interpretation are reported.
