Lines that do not parse as a known directive: invalid_path.

Consequence. A crawler skips what it cannot parse, without reporting anything. A misspelled "Dissalow" leaves a path fully crawlable while the file appears to restrict it.

If that is not intended. Correct the spelling of each field name, and make sure every line follows "Field: value". Rules must also appear after a User-agent line to belong to a group.

• Path '*/search/' should start with '/'L3invalid_path
• Path '*/shop/' should start with '/'L4invalid_path
• Path '*/eshop*' should start with '/'L5invalid_path
• Path '*/estore*' should start with '/'L6invalid_path
• Path '*/unitrun*' should start with '/'L7invalid_path
• Path '*/feedback/' should start with '/'L9invalid_path
• Path '*/promo/' should start with '/'L23invalid_path
• Path '*/download-thanks' should start with '/'L24invalid_path

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.
