WMT Showing Duplicate Meta Description Issues Altough Posts Were Redirected
-
Dear Moz Community,
Some time ago we've change the structure of our website and we've redirected the old URL's to the new ones. About 2,000 posts were redirected at that time.
While checking Webmaster Tools a few days ago I've discovered that about 500 duplicate meta-description issues appear in the "HTML Improvements" area. To my surprise, altough the old posts were redirected to the new path, WMT sees the description of the old posts similar with the one of the new post. Moreover, after changing the structure all meta-descriptions were modified and they weren't the same used before the restructure.
For example I've redirected /blog/taxi-transfer-from-merton-sw19-to-london-city-airport/ to /destinations/greater-london/merton-sw19/taxi-transfer-to-london-city-airport-from-merton/
Now they are shown as having duplicate content. I've checked the redirects and they are working.
I get the same error from the redirected pages for about 150 titles.
Did anyone else get this errors or can you please offer me some suggestions about how I can fix this?
Thank you in advance!
Tiberiu

Yes - assuming this is the final/good page, you have it canonical link to itself.

Dear CleverPHD,
Thank you for your answer. Your advice sounds pretty good but let me see if I got your suggestion clearly. So, from what I understand, you are saying that for the page www.example.com**/blog/taxi-transfer-from-merton-sw19-to-london-city-airport/ **I should add the following as the rel canonical?
Thank you once again!
Best regards,
Tiberiu

I have seen this exact issue before in GWT on a site I work with. It is annoying, but does look to happen on larger sites. Here is what we did to fix our issue. This assumes you already have the proper 301 redirects in place.
-
Add the canonical link to self on all the new pages
-
Wait for Google bot to spider them
-
Wait for GWT to update the status in the report
It is not a quick fix as it takes a while for steps 2 & 3 to cycle though as not all pages are spidered at the same rate. it may take you several months to see it all work itself out.
On this same site, I now also see if I have a new post that I then change the URL and add a 301 that GWT goes through this same process. Again, it is really annoying as I have the 301 in place, I have sent a clear directive to Google that the new page is replacing the old and they show the duplicate error for the old and new URLs in GWT.
I cannot see any logic in why this happens and why the report shows the way that it does. My best guess is that GWT is doing some batch processing and the sequence is off on what is looked at when and so this is a side effect of that process. It is like the spider first sees the new and old URLs from the 301 and logs both URLs. What should happen next is the next batch process should account for the 301 redirects and take out the old URLs, instead the process to check duplicate titles and descriptions runs and generates the duplicate report before the 301 cleanup process can get to it. Disclaimer, I am not a developer etc, but just trying to guess at the logic of "why".
If anyone else has any insight on why this happens, I would love to hear it. I have been able to "fix" the issue using the steps above, but it was in reality not broken to start with. It works out as one of the Moz rx is to use self canonicalizing links to help with scrapers, parameters etc. I just wish GWT was more useful in this sense as I have to sort out all the "errors" to get to the real issues. I end up having to use the Moz crawl or Screaming Frog etc to get at this information.

Tiberiu,
So google WMT is giving these errors? I've had this in the past with a site of a client. Issues were long solved and still Google WMT gives these errors. What does moz.com campaign say? Do the same errors occur here? It could well be a glitch of bug in Google WMT.

Jarno

Same product in different categories and duplicate content issues
Hi,I have some questions related to duplicate content on e-commerce websites. 1)If a single product goes to multiple categories (eg. A black elegant dress could be listed in two categories like "black dresses" and "elegant dresses") is it considered duplicate content even if the product url is unique? e.g www.website.com/black-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/elegant-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/black-elegant-dress unique url > this is the way my products urls look like Does google perceive this as duplicated content? The path to the content is only one, so it shouldn't be seen as duplicated content, though the product is repeated in different categories.This is the most important concern I actually have. It is a small thing but if I set this wrong all website would be affected and thus penalised, so I need to know how I can handle it. 2- I am using wordpress + woocommerce. The website is built with categories and subcategories. When I create a product in the product page backend is it advisable to select just the lowest subcategory or is it better to select both main category and subcategory in which the product belongs? I usually select the subcategory alone. Looking forward to your reply and suggestions. thanks

Tools to test meta descriptions?
Hey does anyone know of any tools which can test your meta descriptions against competitors meta descriptions for specific keyword terms. I know one tool called SERP Turkey which uses mechanical turk, i was wondering if there is any others on the market? Even a tool which can automatically score your meta description against others on the SERP results page. E..g optimised, keyword, call to action, etc. Cheers, Chris

301 Redirect To Another 301 Redirect
Hi, We have a client with an old domain that they want to redirect to their primary domain. They also have a few older domains pointing to the old domain. Do you recommend leaving them as redirects that point to the old domain? This will create a redirect to a redirect situation. Or, is it better to go ahead and redirect those older domains to the primary one's, removing one layer of redirect? Thank you! Jessie

Duplicate on page content - Product descriptions - Should I Meta NOINDEX?
Hi, Our e-commerce store has a lot of product descriptions duplicated - Some of them are default manufacturer descriptions, some are descriptions because the colour of the product varies - so essentially the same product, just different colour. It is going to take a lot of man hours to get the unique content in place - would a Meta No INDEX on the dupe pages be ok for the moment and then I can lift that once we have unique content in place? I can't 301 or canonicalize these pages, as they are actually individual products in their own right, just dupe descriptions. Thanks, Ben

Redirecting a redirect - thoughts?
Hi! A client has just had 14k 404s pop up in his WMT. I think this is because a page that they redirected to had moved. My question is, can I clean these up by redirecting the page the original redirect was one? If so, will it have any negative impact?

Redirect help
I work for a company that has a domain that is something like www.neat-stuff.com but most people just use www.neatstuff.com without the dash. The redirect for the homepage works fine. We recently launched a new site and if you use www.neat-stuff.com/category it redirects from the old site to the new site just fine. However if you use www.neatstuff.com/category it does not properly redirect to www.neat-stuff.com/category. How do I fix that?

Setting up of 301 redirects
Good morning all, As part of the analysis of our website, we have realised that we are diluting our keyword strength in a particular area by having multiple zones all targeting the same keyword. We have decided to combine these zones into one, and set up 301 redirects so that the remaining zone gets the benefit of the other zones' link juice. When setting up a 301 redirect from zone "X" to zone "Y" say, do I need to keep all of the content in zone X, or should I remove all content before the redirect is set up? Does zone Y still get the benefit of zone X's link juice if the content is removed? Many thanks Guy
