Thanks for your help.
I went through my URLs and SEO settings under Settings to review your above list. Below is what I have:
* Document URLs - 'Remember original URLs when moving documents' - true
* Search engine optimization (SEO) - 'Allow permanent (301) redirection' - true
'Redirect document aliases to main URL' - true
All other boxes are empty (no check mark)
What do you mean by this - Another thing you might try is saving document on the Form tab, then saving on the Properties>URLs tab. Depending on that doc types, settings, the URL might be strictly based on a document type field.
I do not use workflow.
I will wait until Monday to run my SEO scan again.
