LowPage has no canonical tag
A self-referencing canonical tag helps search engines choose the right URL when the same page is reachable through several addresses (parameters, trailing slash, http/https).
Fix: Add <link rel="canonical" href="..."> pointing at the preferred URL of the page.
HighPage declares conflicting canonical URLs
More than one canonical tag with different targets was found. Search engines ignore conflicting canonical signals.
Fix: Keep a single canonical tag. Check whether a plugin or theme is adding a second one.
MediumCanonical URL is invalid
The canonical tag does not contain a usable absolute or relative URL.
Fix: Use a full, valid URL in the canonical tag.
HighCanonical points to a URL that is not indexable
The canonical target redirects, returns an error or is set to noindex, so the page is asking search engines to index something that cannot be indexed.
Fix: Point the canonical at a live, indexable URL (usually the page itself).
MediumCanonical points to a page with a different canonical
Canonical chains weaken the signal: the target page names yet another URL as canonical.
Fix: Point every page directly at the final canonical URL.
MediumCanonical points to an http:// URL on an https page
An https page that names an http URL as canonical sends search engines to the insecure version.
Fix: Use the https URL in the canonical tag.
LowCanonical points to another domain
Informational: the page asks search engines to index a different domain instead. That is correct for syndicated content, but a mistake if it is unintended.
Fix: Confirm that the other domain really should be the indexed version.
LowPage is set to noindex
A noindex directive (meta robots or X-Robots-Tag header) keeps the page out of search results. It is intentional for private pages, but a costly mistake on pages you want found.
Fix: Remove the noindex directive if the page should appear in search results.
LowPage tells crawlers not to follow its links
Informational: a nofollow robots directive stops link signals passing from this page.
Fix: Remove it unless you deliberately do not want to vouch for the links on this page.
Criticalrobots.txt blocks our crawler from the whole site
A Disallow: / rule applies to our crawler, so no page could be audited. If the rule also applies to Googlebot the site cannot be crawled for search.
Fix: Remove the blanket Disallow rule or add an Allow rule for the crawler. Remember to remove staging-time blocks after launch.
Highrobots.txt returns a server error
When robots.txt answers with a 5xx error, crawlers assume everything is disallowed.
Fix: Make /robots.txt return 200 (or 404 if you have no rules).
Mediumrobots.txt returns a web page
The /robots.txt URL serves an HTML page (often a soft 404 or single-page-app fallback) instead of rules.
Fix: Serve a plain-text robots.txt or return a real 404.
LowNo robots.txt file
A robots.txt is optional, but it is the standard place to point crawlers to your sitemap.
Fix: Add /robots.txt with a Sitemap: line.
Lowrobots.txt contains lines crawlers cannot parse
Malformed lines are ignored, so the rules may not do what you expect.
Fix: Fix the listed lines.
Lowrobots.txt does not mention the sitemap
A Sitemap: line in robots.txt helps every search engine find your sitemap.
Fix: Add a line such as: Sitemap: https://example.com/sitemap.xml
MediumNo XML sitemap found
We found no sitemap at the locations listed in robots.txt or at /sitemap.xml. Sitemaps help search engines discover and re-crawl pages.
Fix: Publish an XML sitemap and reference it in robots.txt and Search Console.
HighSitemap could not be parsed
The sitemap file is not valid sitemap XML, so search engines cannot use it.
Fix: Regenerate the sitemap and validate it against the sitemaps.org format.
MediumSitemap lists a URL that does not return 200
Sitemaps should contain only live, canonical, indexable URLs. Redirecting or erroring URLs waste crawl budget and reduce trust in the sitemap.
Fix: Remove the URL from the sitemap or fix the page.
MediumSitemap lists a noindex URL
The sitemap asks search engines to index a page that tells them not to.
Fix: Remove the URL from the sitemap, or remove the noindex.
MediumSitemap lists a URL whose canonical is a different page
Sitemaps should list the canonical version of each page.
Fix: List the canonical URL instead.
LowSitemap lists URLs from other hosts
URLs on other hosts in your sitemap are ignored by search engines (and by our crawler).
Fix: List only URLs of this site.
LowSitemap contains malformed URLs
Some <loc> entries are not absolute http(s) URLs.
Fix: Fix the entries.
MediumPaginated page canonicalises to the first page
Pointing page 2, 3... at page 1 can stop the items on later pages from being discovered.
Fix: Give each paginated page a self-referencing canonical.
