Welcome to the Q&A Forum

Hi there,

Moz is just notifying you of the implications of this tag, so there is nothing to worry about if you intended for the canonical tag to be there.

But may I ask why you have the tag on every page of the website? that seems a bit odd to me...

Are all of your links directing to the www version? Then this is what would happen. If you've rel=canonical'ed to the www version, and build links to the non www version, you will essentially build all link juice to the non-www and redirect it to the www, in this process you lose some link juice like you do in 301 redirects.

yea i don't see why it would be a bad thing.

The title says it all - if i have duplicate content on my US and UK website, will adding the hreflang tag help google figure out that they are duplicate for a reason and avoid any penalties?

I'm thinking of hosting a giveaway, and promoting this to bloggers. Thinking of how to go about this, I've run into a sort of a road block. I'm thinking the best way would be to attach a flyer detailing the giveaway so that bloggers have easy access to the information. However, I fear that a lot of them will just copy + paste from the flyer straight to a blog post - which will create a lot of duplicate content.

Anybody in the community willing to share their experiences and how they were able to go around the duplicate content issue?

Hi,

I wouldn't block these pages from being crawled by search engines. Category pages are great for making sure more link juice flows to your deeper blog pages and making sure they get indexed. I believe author links give authorrank to the corresponding blog post too. I'm not sure about what you mean by 'read more' links. May I ask why you are concerned that these pages hurt SEO?
