Dynamic 301's causing duplicate content
-
Hi, wonder if anyone can help?
We have just changed our site which was hosted on IIS and the page url's were like this ( example.co.uk/Default.aspx?pagename=About-Us ). The new page url is example.co.uk/About-Us/ and is using Apache.
The 301's our developer told us to use was in this format:
RewriteCond %{REQUEST_URI} ^/Default.aspx$
RewriteCond %{QUERY_STRING} ^pagename=About-Us$
RewriteRule ^(.*)$ http://www.domain.co.uk/About-Us/ [R=301,L]This seemed to work from a 301 point of view; however it also seemed to allow both of the below URL's to give the same page!
example.co.uk/About-Us/?pagename=About-Us
Webmaster Tools has now picked up on this and is seeing it a duplicate content.
Can anyone help why it would be doing this please. I'm not totally clued up and our host/ developer cant understand it too.
Many Thanks

Right I have done some research... As this was bugging me...
Remove:
RewriteCond %{REQUEST_URI} ^/Default\.aspx$ RewriteCond %{QUERY_STRING} ^pagename=About-Us$ RewriteRule ^(.*)$ http://www.domain.co.uk/About-Us/ [R=301,L]
And replace it with:
``` <code>RewriteCond %{QUERY_STRING} ^pagename=About-Us$ [NC] RewriteRule ^Default\.aspx$ http://www.domain.co.uk/About-Us/? [R=301,L,NC]</code> ``` Test it and let me know...

Are you looking to redirect a single url or many similar URL's ?
-
Ok, maybe someone else will be able to pop in with some more info. Here's a post with a similar issue from Webmaster World:
-
IN that case it didn't work. I was able to visit both urls.
-
If the above rules Rewrite rules work correctly (always check) then it will redirect both Google and humans.
Passing googles page rank from your old page to the new (well most of it anyway).
-
Would this stop example.co.uk/About-Us/?pagename=About-Us working or just stop Google from listing as a dupe?
-
Hi Neil, try this:
RewriteCond %{REQUEST_URI} ^/Default.aspx$
RewriteCond %{REQUEST_URI} ^About-Us/$ RewriteCond %{QUERY_STRING} ^pagename=About-Us$
RewriteRule ^(.*)$ http://www.domain.co.uk/About-Us/ [R=301,L]Hope this helps!

Duplicate content. Competing for rank.
Scenario: An automotive dealer lists cars for sale on their website. The descriptions are very good and in depth at 1,200 words per car. However chunks of the copy are copied from car review websites and weaved into their original copy. Q1: This is flagged in copyscape - how much of an issue is this for Google? Q2: The same stock with the same copy is fed into a popular car listing website - the dealer's website and the classifieds website often rank in the top two positions (sometimes the dealer on top other times the classifieds site). Is this a good or a bad thing? Are you risking being seen as duplicating/scraping content? Thank you.

Bigcommerce & Blog Tags causing Duplicate Content?
Curious why moz would pick up our blog tags as causing duplicate content, when each blog has a rel canonical tag pointing to either the blog post itself and on the tag pages points to the blog as a whole. Kinda want to get rid of the tags in general now, but also feel they can add some extra value to UX later on when we have many more blog posts. Curious if anyone knows a way around this or even a best solution practice when faced with such odd issues? I can see why the duplicate content would happen, but when grouping content into categories?

Duplicate content issue with pages that have navigation
We have a large consumer website with several sections that have navigation of several pages. How would I prevent the pages from getting duplicate content errors and how best would I handle SEO for these? For example we have about 500 events with 20 events showing on each page. What is the best way to prevent all the subsequent navigation pages from getting a duplicate content and duplicate title error?

Duplicate Content... Really?
Hi all, My site is www.actronics.eu Moz reports virtually every product page as duplicate content, flagged as HIGH PRIORITY!. I know why. Moz classes a page as duplicate if >95% content/code similar. There's very little I can do about this as although our products are different, the content is very similar, albeit a few part numbers and vehicle make/model. Here's an example:
Intermediate & Advanced SEO | | seowoody
http://www.actronics.eu/en/shop/audi-a4-8d-b5-1994-2000-abs-ecu-en/bosch-5-3
http://www.actronics.eu/en/shop/bmw-3-series-e36-1990-1998-abs-ecu-en/ate-34-51 Now, multiply this by ~2,000 products X 7 different languages and you'll see we have a big dupe content issue (according to Moz's Crawl Diagnostics report). I say "according to Moz..." as I do not know if this is actually an issue for Google? 90% of our products pages rank, albeit some much better than others? So what is the solution? We're not trying to deceive Google in any way so it would seem unfair to be hit with a dupe content penalty, this is a legit dilemma where our product differ by as little as a part number. One ugly solution would be to remove header / sidebar / footer on our product pages as I've demonstrated here - http://woodberry.me.uk/test-page2-minimal-v2.html since this removes A LOT of page bloat (code) and would bring the page difference down to 80% duplicate.
(This is the tool I'm using for checking http://www.webconfs.com/similar-page-checker.php) Other "prettier" solutions would greatly appreciated. I look forward to hearing your thoughts. Thanks,

Duplicate Titles caused by multiple variations of same URL
Hi. Can you please advise how I can overcome this issue. Moz.com crawle is indicating I have 100's of Duplicate Title tag errors. However this is caused because many URL's have been indexed multiple times in Google. For example. www.abc.com

www.abc.com/?b=123 www.abc.com/ www.abc.com/?b=654 www.abc.com/?b=875 www.abc.com/index.html What can I do to stop this issue being reported as duplictae Titles, as well as content? I was thinking maybe I can use Robots.txt to block various query string parameters. I'm Open to ideas and examples.0 -
Duplicate Content Question
Currently, we manage a site that generates content from a database based on user search criteria such as location or type of business. ..Although we currently rank well -- we created the website based on providing value to the visitor with options for viewing the content - we are concerned about duplicate content issues and if they would apply. For example, the listing that is pulled up for the user upon one search could have the same content as another search but in a different order. Similar to hotels who offer room booking by room type or by rate. Would this dynamically generated content count as duplicate content? The site has done well, but don't want to risk a any future Google penalties caused by duplicate content. Thanks for your help!

Can you be penalized by a development server with duplicate content?
I developed a site for another company late last year and after a few months of seo done by them they were getting good rankings for hundreds of keywords. When penguin hit they seemed to benefit and had many top 3 rankings. Then their rankings dropped one day early May. Site is still indexed and they still rank for their domain. After some digging they found the development server had a copy of the site (not 100% duplicate). We neglected to hide the site from the crawlers, although there were no links built and we hadn't done any optimization like meta descriptions etc. The company was justifiably upset. We contacted Google and let them know the site should not have been indexed, and asked they reconsider any penalties that may have been placed on the original site. We have not heard back from them as yet. I am wondering if this really was the cause of the penalty though. Here are a few more facts: Rankings built during late March / April on an aged domain with a site that went live in December. Between April 14-16 they lost about 250 links, mostly from one domain. They acquired those links about a month before. They went from 0 to 1130 links between Dec and April, then back to around 870 currently According to ahrefs.com they went from 5 ranked keywords in March to 200 in April to 800 in May, now down to 500 and dropping (I believe their data lags by at least a couple of weeks). So the bottom line is this site appeared to have suddenly ranked well for about a month then got hit with a penalty and are not in top 10 pages for most keywords anymore. I would love to hear any opinions on whether a duplicate site that had no links could be the cause of this penalty? I have read there is no such thing as a duplicate content penalty per se. I am of the (amateur) opinion that it may have had more to do with the quick sudden rise in the rankings triggering something. Thanks in advance.

Best solution to get mass URl's out the SE's index
Hi, I've got an issue where our web developers have made a mistake on our website by messing up some URL's . Because our site works dynamically IE the URL's generated on a page are relevant to the current URL it ment the problem URL linked out to more problem URL's - effectively replicating an entire website directory under problem URL's - this has caused tens of thousands of URL's in SE's indexes which shouldn't be there. So say for example the problem URL's are like www.mysite.com/incorrect-directory/folder1/page1/ It seems I can correct this by doing the following: 1/. Use Robots.txt to disallow access to /incorrect-directory/* 2/. 301 the urls like this:
Intermediate & Advanced SEO | | James77
www.mysite.com/incorrect-directory/folder1/page1/
301 to:
www.mysite.com/correct-directory/folder1/page1/ 3/. 301 URL's to the root correct directory like this:
www.mysite.com/incorrect-directory/folder1/page1/
www.mysite.com/incorrect-directory/folder1/page2/
www.mysite.com/incorrect-directory/folder2/ 301 to:
www.mysite.com/correct-directory/ Which method do you think is the best solution? - I doubt there is any link juice benifit from 301'ing URL's as there shouldn't be any external links pointing to the wrong URL's.0
