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.
Notice
The file blocks everything by default
"Disallow: /" applies to "User-agent: *", but 5 Allow rules open specific paths.
Consequence. Any crawler this file does not name is refused every URL. A crawler that is named ignores the wildcard group entirely and follows only its own rules, so the default block does not apply to it.
If that is not intended. To let a new crawler in, give it its own group — adding an Allow to the "User-agent: *" group will not reach it, because a named group replaces the wildcard rather than extending it.
Disallow: /L2Applies to every crawler not named elsewhere
Allow: /$L3Opens this path to crawlers not named elsewhere
Allow: /assetsL4Opens this path to crawlers not named elsewhere
Allow: /help_centerL5Opens this path to crawlers not named elsewhere
Allow: /helpL6Opens this path to crawlers not named elsewhere
Allow: /knowledge_base/L7Opens this path to crawlers not named elsewhere
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.
