Duplicate content and 404 errors
-
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of.
For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index?
also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do

Ali,
If you are on WordPress you can try some of these. First, set up the free Yoast SEO plugin if you have not already.
I have been working on this exact issue. The way Tags are set up (on the client site) we are getting duplicate pages. I am trying a couple of things:
-
In Yoast XML Sitemaps > Taxonomies you can set "Tags" to "Not in Sitemap". Removing them from the XML Sitemap will at least lessen the frequency that Google accesses Taged pages.
-
In Yoast Titles & Meta > Taxonomies you can select Index or Noindex for your Tags.
Following the Tag idea, you might get a 404 if a Tag is changed or deleted. It's hard to diagnose 404s without seeing them. Consider a custom 404 error page, if you have not already. That will at least improve the user experience. With htaccess you set different redirects and custome 404 pages depending on the site section.
Tags in WP don't seem to add much benefit, and probably cause more problems (like dupe content). Even if you are diligent with Tag consisitency, most blogs end up with nearly duplicate Tags.
There are many Moz posts on the topic of duplicate content in WP specific to Tags that might further illuminate your question.
Did you change anything universally, like switch to https? Missed redirects can cause a 404.
The WP Broken Links in Tools will direct you straight to the 404 pages.
Here are some more tips for dealing with 404 in WP:

Hope this helps!

Hi Ali,

Hi Ali,
Please check the title of your pages, if they are same then those links would be counted as duplicates. Also, check how many duplicates are being reported in google webmaster, these are also good indicators for duplicate pages.
This link should help as well
http://a-moz.groupbuyseo.org/learn/seo/duplicate-content
& this is a link to a 301 redirect generator
http://www.htaccessredirect.com
Remember to also use a
Rel=Canonical put this tag in the correct page you want to show people.Then do a 301 redirect on the pages that are duplicates and point them on ONLY right one
As for 404, they will need to be reviewed and handled with 301 to map them to actual URL.
I hope this helps, please feel free to respond if you have further questions.
Regards,
Vijay

Duplicate Content Issues with Pagination
Hi Moz Community, We're an eCommerce site so we have a lot of pagination issues but we were able to fix them using the rel=next and rel=prev tags. However, our pages have an option to view 60 items or 180 items at a time. This is now causing duplicate content problems when for example page 2 of the 180 item view is the same as page 4 of the 60 item view. (URL examples below) Wondering if we should just add a canonical tag going to the the main view all page to every page in the paginated series to get ride of this issue. https://www.example.com/gifts/for-the-couple?view=all&n=180&p=2 https://www.example.com/gifts/for-the-couple?view=all&n=60&p=4 Thoughts, ideas or suggestions are welcome. Thanks

Handling of Duplicate Content
I just recently signed and joined the a-moz.groupbuyseo.org system. During the initial report for our web site it shows we have lots of duplicate content. The web site is real estate based and we are loading IDX listings from other brokerages into our site. If though these listings look alike, they are not. Each has their own photos, description and addresses. So why are they appear as duplicates – I would assume that they are all too closely related. Lots for Sale primarily – and it looks like lazy agents have 4 or 5 lots and input the description the same. Unfortunately for us, part of the IDX agreement is that you cannot pick and choose which listings to load and you cannot change the content. You are either all in or you cannot use the system. How should one manage duplicate content like this? Or should we ignore it? Out of 1500+ listings on our web site it shows 40 of them are duplicates.

How to prevent duplicate content at a calendar page
Hi, I've a calender page which changes every day. The main url is
Technical SEO | | GeorgFranz
/calendar For every day, there is another url: /calendar/2012/09/12
/calendar/2012/09/13
/calendar/2012/09/14 So, if the 13th september arrives, the content of the page
/calendar/2012/09/13
will be shown at
/calendar So, it's duplicate content. What to do in this situation? a) Redirect from /calendar to /calendar/2012/09/13 with 301? (but the redirect changes the day after to /calendar/2012/09/14) b) Redirect from /calendar to /calendar/2012/09/13 with 302 (but I will loose the link juice of /calendar?) c) Add a canonical tag at /calendar (which leads to /calendar/2012/09/13) - but I will loose the power of /calendar (?) - and it will change every day... Any ideas or other suggestions? Best wishes, Georg.0 -

How much to change to avoid duplicate content?
Working on a site for a dentist. They have a long list of services that they want us to flesh out with text. They provided a bullet list of services, we're trying to get 1 to 2 paragraphs of text for each. Obviously, we're not going to write this off the top of our heads. We're pulling text from other sources and trying to rework. The question is, how much rephrasing do we have to do to avoid a duplicate content penalty? Do we make sure there are changes per paragraph, sentence, or phrase? Thanks! Eric
