Are aggregate sites penalised for duplicate page content?
-
Hi all,We're running a used car search engine (http://autouncle.dk/en/) in Denmark, Sweden and soon Germany. The site works in a conventional search engine way with a search form and pages of search results (car adverts).The nature of car searching entails that the same advert exists on a large number of different urls (because of the many different search criteria and pagination). From my understanding this is problematic because Google will penalize the site for having duplicated content. Since the order of search results is mixed, I assume SEOmoz cannot always identify almost identical pages so the problem is perhaps bigger than what SEOmoz can tell us. In your opinion, what is the best strategy to solve this? We currently use a very simple canonical solution.For the record, besides collecting car adverts AutoUncle provide a lot of value to our large user base (including valuations on all cars) . We're not just another leech adword site. In fact, we don't have a single banner.Thanks in advance!

Yeah, having the same listings across multiple domains isn't doing you any favors. The best set up is to have all the languages on one domain and make use of the multilingual canonical support. Not sure if that can be applied across different domains.

Thanks for the answer Oleg.
Just to be clear; my worry is that Google view cars within one country as duplicate content, because they appear on different search URLs. Each country is placed on separate domains, so they should not influence each other.
The car listings are being indexed by Google. My fear was that Google's penalization algorithm works in a gradual way, meaning that maybe we are being penalized for duplicate content, even though the pages are being indexed. Does that sound correct?
Everything related to multilingual works pretty well I believe.

Are the search result pages being indexed? If you just have the car listings indexed and have correct multilingual alternative tags set up, you should be in good shape. Change up the content to match the specific countries language & currency.
Multilingual search might be more difficult to manage since they use different search terms.

Duplicate Content - Different URLs and Content on each
Seeing a lot of duplicate content instances of seemingly unrelated pages. For instance, http://www.rushimprint.com/custom-bluetooth-speakers.html?from=topnav3 is being tracked as a duplicate of http://www.rushimprint.com/custom-planners-diaries.html?resultsperpg=viewall. Does anyone else see this issue? Is there a solution anyone is aware of?

Duplicate Content Brainstorming
Hi, New here in the SEO world. Excellent resources here. We have an ecommerce website that sells presentation templates. Today our templates come in 3 flavours - for PowerPoint, for Keynote and both - called Presentation Templates. So we've ended up with 3 URLS with similar content. Same screenshots, similar description.. Example: https://www.improvepresentation.com/keynote-templates/social-media-keynote-template https://www.improvepresentation.com/powerpoint-templates/social-media-powerpoint-template https://www.improvepresentation.com/presentation-templates/social-media-presentation-template I know what you're thinking. Why not make a website with a template and give 3 download options right? But what about https://www.improvepresentation.com/powerpoint-templates/ https://www.improvepresentation.com/keynote-templates/ These are powerfull URL's in my opinion taking into account that the strongest keyword in our field is "powerpoint templates" How would you solve this "problem" or maybe there is no problem at all.

Search/Search Results Page & Duplicate Content
If you have a page whose only purpose is to allow searches and the search results can be generated by any keyword entered, should all those search result urls be no index or rel canonical? Thanks.

Google inconsistent in display of meta content vs page content?
Our e-comm site includes more than 250 brand pages - lrg image, some fluffy text, maybe a video, links to categories for that brand, etc. In many cases, Google publishes our page title and description in their search results. However, in some cases, Google instead publishes our H1 and the aforementioned fluffy page content. We want our page content to read well, be descriptive of the brand and appropriate for the audience. We want our meta titles and descriptions brief and likely to attract CTR from qualified shoppers. I'm finding this difficult to manage when Google pulls from two different areas inconsistently. So my question... Is there a way to ensure Google only utilizes our title/desc for our listings?

Duplicate Page Content and Titles
A few weeks ago my error count went up for Duplicate Page Content and Titles. 4 errors in all. A week later the errors were gone... But now they are back. I made changes to the Webconfig over a month ago but nothing since. SEOmoz is telling me the duplicate content is this http://www.antiquebanknotes.com/ and http://www.antiquebanknotes.com Thanks for any advise! This is the relevant web.config. <rewrite><rules><rule name="CanonicalHostNameRule1"><match url="(.*)"><conditions><add input="{HTTP_HOST}" pattern="^www.antiquebanknotes.com$" negate="true"></add></conditions>

Video thumbnail pages with "sort" feature -- tons of duplicate content?
A client has 2 separate pages for video thumbnails. One page is "popular videos" with a sort function for over 700 pages of video thumbnails with 10 thumbnails and short desriptions per page. (/videos?sort_by=popularity). The second page is "latest videos" (/videos?sort_by=latest) with over 7,000 pages. Both pages have a sort function -- including latest, relevance, popularity, time uploaded, etc. Many of the same video thumbnails appear on both pages. Also, when you click a thumbnail you get a full video page and these pages appear to get indexed well. There seem to be duplicate content issues between the "popular" and "latest" pages, as well as within the sort results on each of those pages. (A unique URL is generated everytime you use the sort function i.e. /videos?sort_by=latest&uploaded=this_week). Before my head explodes, what is the best way to treat this? I was thinking a noindex,follow meta robot on every page of thumbnails since the individual video pages are well indexed, but that seems extreme. Thoughts?

50+ duplicate content pages - Do we remove them all or 301?
We are working on a site that has 50+ pages that all have duplicate content (1 for each state, pretty much). Should we 301 all 50 of the URLs to one URL or should we just completely get rid of all the pages? Are there any steps to take when completely removing pages completely? (submit sitemap to google webmaster tools, etc) thanks!
