Why are my 301 redirects and duplicate pages (with canonicals) still showing up as duplicates in Webmaster Tools?
-
My guess is that in time Google will realize that my duplicate content is not actually duplicate content, but in the meantime I'd like to get your guys feedback.
The reporting in Webmaster Tools looks something like this.
Duplicates
- /url1.html
- /url2.html
- /url3.html
- /category/product/url.html
- /category2/product/url.html
url3.html is the true canonical page in the list above._ url1.html,_ and url2.html are old URLs that 301 to url3.html. So, it seems my bases are covered there.
_/category/product/url.html _and _/category2/product/url.html _ do not redirect. They are the same page as url3.html. Each of the category URLs has a canonical URL of url3.html in the header. So, it seems my bases are covered there as well.
Can I expect Google to pick up on this? Why wouldn't it understand this already?

Hi Tyler,
Is this still going on? My first reaction would be to say that Google will probably figure it out over time and the notifications will disappear/not reoccur. Have you seen new notifications of duplicate content since you made these changes?
Are these pages still appearing in the index? If not I wouldn't be super concerned - WMT updates lag behind what's going on in the index by quite a bit. If they are, take a look at the cache date - it may be that Google needs to crawl these pages again to find the canonical tag.
Since Google doesn't always "get" canonical tags, you may not see this error go away in WMT - as long as those pages are no longer ranking for anything, though, you should be OK. The redirects should stop registering as duplicate content sooner rather than later, though.
-
Preferred version is already set to WWW. Also, all canonicals point to the same URL and I do not have more than one per page.
-
Do you have more than 1 canonical tag on any of these pages? If you do, Google will ignore any tag.
Have you set the preferred version of your site? Is it possible that Google sees both the www and non www versions of your site?

How many people on the moz community here have implemented this strategy in practical and can share some insights and pros and cons of doing 301 redirects? Many Thanks.

Delete old blog posts after 301 redirects to new pages?
Hi Moz Community, I've recently created several new pages on my site using much of the same copy from blog posts on the same topics (we did this for design flexibility and a few other reasons). The blogs and pages aren't exactly identical, as the new pages have much more content, but I don't think there's a point to having both and I don't want to have duplicate content, so we've used 301 redirects from the old blog posts to the new pages of the same topic. My question is: can I go ahead and delete the old blog posts? (Or would there be any reasons I shouldn't delete them?) I'm guessing with the 301 redirects, all will be well in the world and I can just delete the old posts, but I wanted to triple check to make sure. Thanks so much for your feedback, I really appreciate it!

301 redirect syntax for htaccess
I'm working on some htaccess redirects for a few stray pages and have come across a few different varieties of 301s that are confusing me a bit....Most sources suggest: Redirect 301 /pageA.html http://www.site.com/pageB.html or using some combination of: RewriteRule + RewriteCond + RegEx I've also found examples of: RedirectPermanent /pageA.html http://www.site.com/pageB.html I'm confused because our current htaccess file has quite a few (working) redirects that look like this: Redirect permanent /pageA.html http://www.site.com/pageB.html This syntax seems to work, but I'm yet to find another Redirect permanent in the wild, only examples of Redirect 301 or RedirectPermanent Is there any difference between these? Would I benefit at all from replacing Redirect permanent with Redirect 301?

URL structure change for pages without traffic: 301 redirect or not ?
Hi, I am just starting with MOZ PRO and trying to handle the high priority issues, starting with pages with 4XX Client Error. I am wondering what we should do with pages with no traffic and no external links. For instance: So time ago we change the URL structure of our blog to a flatter one, and so eg we moved a page: from: domain-name/dla-rodzicow/poradniki/poradniki-po-markach/vilac/vilac-zabawki-z-dusza to: domain-name/dla-rodzicow/poradniki/marka-vilac/vilac-zabawki-z-dusza/ Still not very flat but this is not the point. MOZ PRO shows we are having internal links to the old url. According to MOZ PRO, we don't have external links. According to Analytics we have no traffic on the old page. So now we changed the internal link, and I am wondering whether we should 301 redirect the old page to the new one, or whether a sitemap update is enough for this kind of pages ? Thanks in advance for your help.

How to get google to forget my old but still working page and list my new fully optimized page for a keyword?
Hi There! (i am beginner in seo) I have dynamic and static pages on our site. I created a static page for a specific keyword. Fully optimized it, (h1, alt, metas, etc.....maybe too optimized). My problem is that this page is alive for weeks, checked it in GWT and it is in robots.txt, google sees it, and indexed it. BUT whenewer i do a search for that keyword, we still appear with the dynamically created link in the google listings. How could i "redirect" google, if sy make a search for that keyword than shows our optimized page? Is there a tool for that? I cant delete the dynamic page... Any ideas? Thx Andrew

301 redirects
Hi Guys, Question,
Technical SEO | | VividLime
Lets say I have a page oldfile.php at position #2 then set-up a redirection in the following way 100 incoming external links--> oldfile.php [301 to] newfile.php Google comes along and updates its index to newfile.php and ranking of newfile.php remains at position #2. Everything is good. Lets say in 5months, I come along and delete oldfile.php so we have
100 incoming external links--> deleted(oldfile.php) or 100 incoming external links-->404 error. |||| newfile.php Do I then loose the rankings on newfile.php. My thinking is that now that all the external links now point to a page not found, newfile.php should loose rankings Am I correct in my assumption?0 -
301 Redirects
Hello, I have a problem with my website. I have a page on my website http://www.ensorbuilding.com/page.php/aboutus but if i type in www.ensorbuilding.com/page.php/aboutus/f8e45e9d9df6140bb5a7ff1173e8d828 or www.ensorbuilding.com/page.php/aboutus/0f0eea5e9ab0a3e8d91fad8fc0d3ce9c it still displays the about us page. Google is seeing this as duplicate content so what I would want to do is 301 redirect anything after www.ensorbuilding.com/page.php/aboutus . How could I implement a 301 redirect in this way?
