Detailed Analysis

Warning

1 rule names a location nobody would have guessed

Rules name a sensitive location made specific by a qualifier or by where it sits, or a spreadsheet by its full path.

Consequence. A bare "/backup" is in every scanner wordlist; "/backup-2023/" is in none. Listing it advertises the location to the readers least likely to honour the rule.

If that is not intended. Put these locations behind authentication or remove them; once they are protected, the line can stay or go. Responses behind authentication are not indexed, so they need no "noindex". Content that is public by design and only has to stay out of search wants a "noindex" without the Disallow: a crawler only sees a noindex on a page it may fetch.

  • Disallow: /feed/privateL16"private" below the first level
Notice

1 rule can never take effect

A broader rule of the same type already covers these paths.

Consequence. These lines change nothing. They are harmless, but they add length to a file that has a size limit, and they make the real policy harder to read.

If that is not intended. Remove the redundant rules, or narrow the broader rule if it is catching more than intended.

  • allow: /subscribeL27Already covered by "allow: /" on line 26
Info

1 rule suggests sensitive files may exist

Wildcard patterns name no location, but suggest such files may exist under public paths.

Consequence. A pattern such as "/*.sql$" discloses nothing a reader can request directly. It does say what kind of file the site expects to have lying around.

If that is not intended. Verify that files matching these patterns are not served.

Not checked

Page directives were not checked

The page answered HTTP , so its meta robots tags and X-Robots-Tag headers were not read.

Consequence. Nothing is known about whether this page asks to be kept out of search results. Its absence of directives here proves nothing either way.

If that is not intended. Analyse the page again once it answers normally to our bot.

Pass

2 sitemaps declared

Every declared sitemap is an absolute URL and is crawlable.

  • https://substack.com/sitemap.xmlL30
  • https://substack.com/news_sitemap.xmlL31
Pass

No syntax problems

Every line parses as a directive crawlers understand.
