Find and fix X-Robots tag noindex
Indexing rules in the HTTP header are easily overlooked.
Indexing rules in the HTTP header are easily overlooked crawling and indexing errors are especially serious if important pages are not found, understood or indexed as a result.
Finding Indexation Bans in the HTTP Header
A PDF does not have an HTML head. If it is to be excluded from indexing, an X-Robots tag in the HTTP header can be responsible for this. However, the same header can also unintentionally hit public HTML pages due to a too broad server rule.
Example: Recognizing the Result
Illustrative example: The HTML source text does not contain noindex, but the server sends X-Robots tag: noindex. A sole examination of the meta tags overlooks the exclusion.
HTTP/2 200
Content-Type: text/html
X-Robots-Tag: noindex
Limit cause and implement correction
Targeted limitation of the cause
Check the headers of the specific target response and each forwarding. Look for X-Robots tag and crawler-related variants. If HTML meta tags are inconspicuous, compare rules in the web server, CDN, and download handler. An index value in HTML does not reliably cancel out a noindex that is effective elsewhere.
Change and follow-up audit
Limit or remove the triggering rule only for content that should actually be indexable. For private downloads, the exclusion may be intended; confidential files also require access protection. A robots.txt lock may prevent the crawler from even being able to read the changed header.
Check the final response again with a normal retrieval and then check important URLs in the Search Console. The technical correction can be checked immediately; a change in the search index takes place only after reprocessing.
What makes you recognize a suitable correction
Check the GET response header of the affected URL and limit the rule in application, server or CDN to the intended path.
Classification and boundaries
When is this indication not a clear error?
For confidential content, an indexation ban is not sufficient as access protection. For deliberately excluded downloads, the header can be correct.
Further documentation
X-Robots tag noindex after CMS and cause
Many audit messages can be resolved faster if they are grouped by system, page type and technical cause. CMS indentations are only linked where X-Robots tag noindex has a clear cause or fixed route in the respective system.
For this error, there is currently no own CMS deepening, because the correction is usually not sufficiently system-specific. Take advantage of the general causes and checks on this page.
