I've got duplicate pages. For example, blog/page/2 is the same as author/admin/page/2\. Is this something I should just ignore, or should I create the author/admin/page2 and then 301 redirect?

I'm going through the crawl report and it says I've got duplicate pages. For example, blog/page/2 is the same as   author/admin/page/2/  Now, the author/admin/page/2 I can't even find in WordPress, but it is the same thing as blog/page/2 nonetheless. Is this something I should just ignore, or should I create the author/admin/page2 and then 301 redirect it to blog/page/2?

Hello! I too think of some places ... I usually ignore these messages, provided they do not find the page
I think the tool is not 100% accurate !!

Hey Michael,

Better safe than sorry. If you are picking up duplicate pages, you could get slapped with some duplicate content issues. This won't get you blacklisted by any means...but it can help push your results away from the spotlight.

In a situation like this, I would advise blocking these types of pages from bots - but do not redirect them (that could cause some serious issues for navigation)! Also, using your rel="canonical" can be helpful pointing out the original source of content.

Example robots.txt

User-agent: *
Disallow: /author

Note this will block anything after author...so author/admin/, author/admin/page, etc.

I'd take a slightly different approach to solving your issue though blocking the pages will work.  My only concern with doing that is that if you do any weight to that page will evaporate from your site as opposed to being passed back internally.  You won't be finding the pages in Wordpress as they're auto-generated and I'm guessing there's only one author which is why the author archive would be the same as the general archive.

Assuming you're using Yoast you can remedy the issue by simply going to the Titles & Metas area, selecting the "Archives" tab and check the box next to "Add noindex, follow to the author archives".  This will allow the PageRank to pass but the page won't be indexed as duplicate content.  There are other types of pages int eh same area you can do the same thing for.

As an aside, you should change your username.  From the example you've given I'm assuming you've left the user as "admin".  Since that's the default for Wordpress it makes it easier for attacks to brute-force their way in as they already have the username.  This can be done via phpMyAdmin to just change it but if you're not comfortable in there you can simply create a different user with Admin privileges and delete the old "admin" making sure to attribute all posts and pages to the new user.

I shouldn't have to say this but just in case something goes wrong BE SURE TO BACK UP YOUR DATABASE !
