Skipped Links Codes Documentation

[jzeisloft]

Hello,

I have a number of skipped links with various codes associated with each link.  For instance, the codes 'lu' and 'mrob' appear frequently.  Is there documentation on the meaning of the codes that are associated with skipped links?

Thanks for your help.

Hello,

this is undocumented feature.
"lu" means that page is redirect to another located or canonical meta tag points to a different URL.
"mrob" means that robots meta tag blocks the page from indexing.
