The file contains no "Sitemap:" line.

Consequence. Crawlers have to discover every URL by following links. Pages that are deep, newly published, or poorly linked internally take longer to be found, and some may never be. A sitemap is the most direct way to hand a crawler the full list.

If that is not intended. Publish an XML sitemap and declare it with an absolute URL, e.g. "Sitemap: https://example.com/sitemap.xml". The line is global — it belongs outside any User-agent group and applies to every crawler.

Crawl-delay was never part of the standard. Google has never supported it; Bing and Yandex do.

Consequence. Any rate limit intended for Googlebot is not being applied. If the goal was to reduce load from Google specifically, it is not working.

If that is not intended. Set the crawl rate for Google in Search Console instead. Keep the directive if the limit is meant for Bing or Yandex, which do honour it.

• Crawl-delay: 1L24

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.
