'Duplicate pages without canonical' error

Hi,

I am getting an errors in Ahrefs for ‘Duplicate pages without canonical’ - with pages like news-articles/tag/news/page/8 and author pages showing up.

Could someone explain how to fix this?

Hi @JCodrington,

HubSpot has a step-by-step instruction in the knowledgebase here: Set canonical URLs for duplicate content

Best regards!

Thanks for your reply @karstenkoehler - however I have done all that! I mean that just the author, tag and subsequential blog listing pages are showing up in Ahrefs as ‘Duplicate pages without canonical’ - see attached image of examples… Unless I put something into the robots txt file (which I’m not sure is a good idea) then is there anything I can do for this? Or do I simply just ignore it :sweat_smile:
