Duplicate content http:// something .com and http:// something .com/
-
Hi,
I've just got a crawl report for a new wordpress blog with suffusion theme and yoast wordpress seo module and there is duplicate content for:
http:// something .com
and
http:// something .com/
I just can't figure out how to handle this. Can I add a redirect for .com/ to .com in htaccess?
Any help is appreciated!
By the way, the tag value for rel canonical is **http:// something .com/ **for both.

All so rember the canonicalization SEO advice: url canonicalization by MATT CUTTS on JANUARY 4, 2006 in GOOGLE/SEO (I got my power back!) Before I start collecting feedback on the Bigdaddy data center, I want to talk a little bit about canonicalization, www vs. non-www, redirects, duplicate urls, 302 “hijacking,” etc. so that we’re all on the same page. Q: What is a canonical url? Do you have to use such a weird word, anyway? A: Sorry that it’s a strange word; that’s what we call it around Google. Canonicalization is the process of picking the best url when there are several choices, and it usually refers to home pages. For example, most people would consider these the same urls: www.example.com example.com/ www.example.com/index.html example.com/home.asp But technically all of these urls are different. A web server could return completely different content for all the urls above. When Google “canonicalizes” a url, we try to pick the url that seems like the best representative from that set. Q: So how do I make sure that Google picks the url that I want? A: One thing that helps is to pick the url that you want and use that url consistently across your entire site. For example, don’t make half of your links go to http://example.com/ and the other half go to http://www.example.com/ . Instead, pick the url you prefer and always use that format for your internal links. Q: Is there anything else I can do? A: Yes. Suppose you want your default url to be http://www.example.com/ . You can make your webserver so that if someone requests http://example.com/, it does a 301 (permanent) redirect to http://www.example.com/ . That helps Google know which url you prefer to be canonical. Adding a 301 redirect can be an especially good idea if your site changes often (e.g. dynamic content, a blog, etc.). Q: If I want to get rid of domain.com but keep www.domain.com, should I use the url removal tool to remove domain.com? A: No, definitely don’t do this. If you remove one of the www vs. non-www hostnames, it can end up removing your whole domain for six months. Definitely don’t do this. If you did use the url removal tool to remove your entire domain when you actually only wanted to remove the www or non-www version of your domain, do a reinclusion request and mention that you removed your entire domain by accident using the url removal tool and that you’d like it reincluded. Q: I noticed that you don’t do a 301 redirect on your site from the non-www to the www version, Matt. Why not? Are you stupid in the head? A: Actually, it’s on purpose. I noticed that several months ago but decided not to change it on my end or ask anyone at Google to fix it. I may add a 301 eventually, but for now it’s a helpful test case. Q: So when you say www vs. non-www, you’re talking about a type of canonicalization. Are there other ways that urls get canonicalized? A: Yes, there can be a lot, but most people never notice (or need to notice) them. Search engines can do things like keeping or removing trailing slashes, trying to convert urls with upper case to lower case, or removing session IDs from bulletin board or other software (many bulletin board software packages will work fine if you omit the session ID). Q: Let’s talk about the inurl: operator. Why does everyone think that if inurl:mydomain.com shows results that aren’t from mydomain.com, it must be hijacked? A: Many months ago, if you saw someresult.com/search2.php?url=mydomain.com, that would sometimes have content from mydomain. That could happen when the someresult.com url was a 302 redirect to mydomain.com and we decided to show a result from someresult.com. Since then, we’ve changed our heuristics to make showing the source url for 302 redirects much more rare. We are moving to a framework for handling redirects in which we will almost always show the destination url. Yahoo handles 302 redirects by usually showing the destination url, and we are in the middle of transitioning to a similar set of heuristics. Note that Yahoo reserves the right to have exceptions on redirect handling, and Google does too. Based on our analysis, we will show the source url for a 302 redirect less than half a percent of the time (basically, when we have strong reason to think the source url is correct). Q: Okay, how about supplemental results. Do supplemental results cause a penalty in Google? A: Nope. Q: I have some pages in the supplemental results that are old now. What should I do? A: I wouldn’t spend much effort on them. If the pages have moved, I would make sure that there’s a 301 redirect to the new location of pages. If the pages are truly gone, I’d make sure that you serve a 404 on those pages. After that, I wouldn’t put any more effort in. When Google eventually recrawls those pages, it will pick up the changes, but because it can take longer for us to crawl supplemental results, you might not see that update for a while. That’s about all I can think of for now. I’ll try to talk about some examples of 302′s and inurl: soon, to help make some of this more concrete. http://www.ragepank.com/articles/3/preventing-duplicate-content/ Hope I was of help, Thomas Von Zickell

thanks!
Can some body please also clarify exactly what should be in the second line:
As eyepaq wrote: RewriteRule ^(.+)/$ [%{HTTP_HOST}...] [R=301,L]
Should I insert something in/after "[%{HTTP_HOST}...]"?

After RewriteEngine if i'm not wrong

Should I keep the existing wordpress rewrite? If I keep it, should I then place your code before or after?
BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
END WordPress

Hi,
Google is pretty good in understanding that the trailing slash version is the same with the non-trailing slash version so you are safe on that side.
Even if the crawler said this is an issue it's not something you should focus on.
However, if you want to play by the book, you can httaccess it so it will 301 redirect to oen or another.
Bellow is a sample code:
#get rid of trailing slashes
RewriteCond %{HTTP_HOST} ^(www.)?example.com$ [NC]
RewriteRule ^(.+)/$ [%{HTTP_HOST}...] [R=301,L]Hope it helps.

I'm looking to put a quite length FAQs tab on product pages on an ecommerce site. Am I likely to have duplicate content issues?
On an ecommerce site we have unique content on the product pages (i.e. descriptions), as well as the usual delivery and returns tabs for customer convenience. From this we haven't had any duplicate content issues or warnings, which seems to be the case industry-wide. However, we're looking to add a more lengthy FAQs tab which is still highly relevant to the customer but contains a lot more text than the other tabs. The product descriptions are also relatively small. Do you think this will cause potential duplicate content issues or should it be treated the same as a delivery tab, for instance?

301 redirected Duplicate Content, still showing up as duplicate after new crawl.
We launched a site where key landing pages were not showing up in google. After running the seomoz crawl it returned a lot of duplicate pages which may expalin this. The actual url of the page is /design and it was telling me the following were dupes: /design/family-garden-design
On-Page Optimization | | iterate
/design/small-garden-design
/design/large-rural-garden-design
/Design All of these URL's were in fact pointing to the /design landing page. I 301 redirected all of the pages so they all now resolve to /design After running another crawl the day after doing this it's still showing up as duplicate content on seomoz. Does seomoz evaluate the new changes right away?0 -
Are these considered duplicates?
http://www.domain.com/blog/sample-blog-post/#more-0001 http://www.domain.com/blog/sample-blog-post/ The first URL is coming from a "click here" hyperlink from the excerpt of the 2nd URL in my homepage. Thanks in advance!

Duplicate Content - Site Wide or Internet Wide?
Hello... I am creating a new website and i was wondering how you guys would define duplicate content? If my new site had the same page titles and descriptions as my existing site, would that be duplicate content? Or does duplicate content mean same titles and descriptions in the same site? I'm wondering if i can upload the same database (with page titles and descriptions and alt tags) to my new site or if that would be looked at as duplicate... Thanks

User experience regarding dulpicate content and managing this content with google.
Hi long title i know! We are moving on to magento and have chosen to allocate a specific colour to each category using corresponding tabbed navigation for user experience.All products within each of the coloured tabs then inherit the repective colour, giving the products a category identiy within the store. This layout has had a positive feedback from our "testers" As a lot of our products are seasonal and can be represented in different categories there is a significant amount of duplicate content. ATM i see our options as being: Alter the site structure so that the category is not shown in the url, therefore eliminating our duplicate products. The downside of this is that the colour co-ordination of the categories would not work at product level as its the category path that assigns the colour. create canonical links for every duplicate, can this be damaging? keep the duplicates and do nothing let google decide the most important version of a product. any guidance would be appreciated!

Duplicate pages
Hi, I am using a CMS that generates dynamic urls that according to the SeoMoz tool will be indexed as duplicate pages. The pages in questions are forms, blog-posts etc. that are not crucial to achieve ranking for. I do worry though about the consequences of having 20 (non-duplicate)pages with static urls and about 100 pages that are duplicates with dynamic urls. What consequences will this have for the speed that the robots crawl the site and could there be negative effects on ranking for the entire domain?
