Duplicate Content Through Sorting
-
I have a website that sells images. When you search you're given a page like this:
http://www.andertoons.com/search-cartoons/santa/
I also give users the option to resort results by date, views and rating like this:
http://www.andertoons.com/search-cartoons/santa/byrating/
I've seen in SEOmoz that Google might see these as duplicate content, but it's a feature I think is useful. How should I address this?
-
This is a perfect opportunity to use the canonical tag: http://www.google.com/support/webmasters/bin/answer.py?answer=139394 so that only one of these pages is indexed.
-
If you use just used robots.txt to block the byrating directory that would probably be simplest. SEOmoz will still flag the pages up as errors but this is an intentional use to reduce duplicate content.

Semi-duplicate content yet authoritative site
So I have 5 real estate sites. One of those sites is of course the original, and it has more/better content on most of the pages than the other sites. I used to be top ranked for all of the subdivsion names in my town. Then when I did the next 2-4 sites, I had some sites doing better than others for certain keywords, and then I have 3 of those sites that are basically the same URL structures (besides the actual domain) and they aren't getting fed very many visits. I have a couple of agents that work with me that I loaned my sites to to see if that would help since it would be a different name. My same youtube video is on each of the respective subdivision pages of my site and theirs. Also, their content is just rewritten content from mine about the same length of content. I have looked over and seen a few of my competitors who only have one site and their URL structures arent good at all, and their content isn't good at all and a good bit of their pages rank higher than my main site which is very frustrating to say the least since they are actually copy cats to my site. I sort of started the precedent of content, mapping the neighborhood, how far that subdivision is from certain landmarks, and then shot a video of each. They have pretty much done the same thing and are now ahead of me. What sort of advice could you give me? Right now, I have two sites that are almost duplicate in terms of a template and same subdivsions although I did change the content the best I could, and that site is still getting pretty good visits. I originally did it to try and dominate the first page of the SERPS and then Penguin and Panda came out and seemed to figure that game out. So now, I would still like to keep all the sites, but I'm assuming that would entail making them all unique, which seems to be tough seeing as though my town has the same subdivisions. Curious as to what the suggestions would be, as I have put a lot of time into these sites. If I post my site will it show up in the SERPS? Thanks in advance

Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0 -
3rd Party hosted whitepapers — bad idea? Duplicate content?
It is common the B2B world to have 3rd parties host your whitepapers for added exposure. Is this a bad practice from an SEO point of view? Is the expectation that the 3rd parties use rel=canonical tags? I doubt most of them do . . .

PDF for link building - avoiding duplicate content
Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.

How to manage duplicate content?
I have a real estate site that contains a large amount of duplicate content. The site contains listings that appear both on my clients website and on my competitors websites(who have better domain authority). It is critical that the content is there because buyers need to be able to find these listings to make enquiries. The result is that I have a large number pages that contain duplicate content in some way, shape or form. My search results pages are really the most important ones because these are the ones targeting my keywords. I can differentiate these to some degree but the actual listings themselves are duplicate. What strategies exist to ensure that I'm not suffereing as a result of this content? Should I : Make the duplicate content noindex. Yes my results pages will have some degree of duplicate content but each result only displays a 200 character summary of the advert text so not sure if that counts. Would reducing the amount of visible duplicate content improve my rankings as a whole? Link back to the clients site to indicate that they are the original source Any suggestions?

Pop Up Pages Being Indexed, Seen As Duplicate Content
I offer users the opportunity to email and embed images from my website. (See this page http://www.andertoons.com/cartoon/6246/ and look under the large image for "Email to a Friend" and "Get Embed HTML" links.) But I'm seeing the ensuing pop-up pages (Ex: http://www.andertoons.com/embed/5231/?KeepThis=true&TB_iframe=true&height=370&width=700&modal=true and http://www.andertoons.com/email/6246/?KeepThis=true&TB_iframe=true&height=432&width=700&modal=true) showing up in Google. Even worse, I think they're seen as duplicate content. How should I deal with this?

Mobile version creating duplicate content
Hi We have a mobile site which is a subfolder within our site. Therefore our desktop site is www.mysite.com and the mobile version is www.mysite.com/m/. All URL's for specific pages are the same with the exception of /m/ in them for the mobile version. The mobile version has the specific user agent detection capabilities. I never saw this as being duplicate content initially as I did some research and found the following links

http://searchengineland.com/dont-penalize-yourself-mobile-sites-are-not-duplicate-content-40380
http://www.seroundtable.com/archives/022109.html What I am finding now is that when I look into Google Webmaster Tools, Google shows that there are 2 pages with the same Page title and therefore Im concerned if Google sees this as duplicate content. The reason why the page title and meta description is the same is simply because the content on the 2 verrsions are the exact same. Only layout changes due to handheld specific browsing. Are there any speficific precausions I could take or best practices to ensure that Google does not see the mobile pages as duplicates of the desktop pages Does anyone know solid best practices to achieve maximum results for running an idential mobile version of your main site?1
