Duplicate content throughout multiple URLs dilemma
-
We have a website with lots of categories and there are problems that some subcategories have identical content on them.
So, is it enough to just add different text on those problematic subcategories or we need to use "canonical" tag to main category.
Same dilemma is with our search system and duplicate content. For example, "/category/sports" URL would have similar to identical content with "/search/sports" and "/search/sports-fitness/" URLs.
Ranking factors is important for all different categories and subcategories. Ranking factors is also important for search individual keywords. So, the question is, how to make them somehow unique/different to rank on all those pages well?
Would love to hear advices how it can be solved using different methods and how it would affect our rankings. When we actually need to use "canonical" tag and when 301 redirect is better. Thanks!

Commonly on large ecommerce websites duplication between categories and sub categories is an issue. The views of search results can also be a factor IE: grid, list, etc-
Association the sub categories with the main top level categories by using the canonical tag. It is also a possibility to block the /search/ results by using the robots.txt- search results aren't the most beneficial to the user and this is a ranking factor.
The canonical tags are exceptionally effective for ecommerce structures.

Penalties for duplicate content
Hello!We have a website with various city tours and activities listed on a single page (http://vaiduokliai.lt/). The list changes accordingly depending on filtering (birthday in Vilnius, bachelor party in Kaunas, etc.). The URL doesn't change. Content changes dynamically. We need to make URL visible for each category, then optimize it for different keywords (for example city tours in Vilnius for a list of tours and activities in Vilnius with appropriate URL /tours-in-Vilnius).The problem is that activities overlap very often in different categories, so there will be a lot of duplicate content on different pages. In such case, how severe penalty could be for duplicate content?

Duplicate content in external domains
Hi,
Intermediate & Advanced SEO | | teconsite
I have been asking about this case before, but now my question is different.
We have a new school that offers courses and programs . Its website is quite new (just a five months old) It is very common between these schools to publish the courses and programs in training portals to promote those courses and to increase the visibility of them. As the website is really new, I found when I was doing the technical audit, that when I googled a text snipped from the site, the new school website was being omitted, and instead, the course portals are being shown. Of course, I know that the best recommendation would be to create a different content for that purpose, but I would like to explore if there is more options. Most of those portals doesn't allow to place a link to the website in the content and not to mention canonical. Of course most of them are older than the new website and their authority is higher. so,... with this situation, I think the only solution is to create a different content for the website and for the portals.
I was thinking that maybe, If we create the content first in the new website, send it to the index, and wait for google to index it, and then send the content to the portals, maybe we would have more opportunites to not be ommited by Google in search results. What do you think? Thank you!0 -
Duplicate Content Pages - A Few Queries..
I am working through the latest Moz Crawl Report and focusing on the 'high priority' issues of Duplicate Page Content. There are some strange instances being flagged and so wondered whether anyone has any knowledge as to why this may be happening... Here is an example; This page; http://www.bolsovercruiseclub.com/destinations/cruise-breaks-&-british-isles/bruges/ ...is apparently duplicated with these pages; http://www.bolsovercruiseclub.com/guides/excursions http://www.bolsovercruiseclub.com/guides/cruises-from-the-uk http://www.bolsovercruiseclub.com/cruise-deals/norwegian-star-europe-cruise-deals Not sure why...? Also, pages that are on our 'Cruise Reviews' section such as this page; http://www.bolsovercruiseclub.com/cruise-reviews/p&o-cruises/adonia/cruising/931 ...are being flagged as duplicated content with a page like this; http://www.bolsovercruiseclub.com/destinations/cruise-breaks-&-british-isles/bilbao/ Is this a 'thin content' issue i.e. 2 pages have 'thin content' and are therefore duplicated? If so, the 'destinations' page can (and will be) rewritten with more content (and images) but the 'cruise reviews' are written by customers and so we are unable to do anything there... Hope that all makes sense?! Andy

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

Wordpress Duplicate Content Due To Allocating Two Post Categories
It looks like google has done a pretty deep crawl of my site and is now showing around 40 duplicate content issues for posts that I have tagged in two seperate categories for example: http://www.musicliveuk.com/latest-news/live-music-boosts-australian-economy http://www.musicliveuk.com/live-music/live-music-boosts-australian-economy I use the all in one SEO pack and have checked the no index for categories, archive, and tag archive boxes so google shouldn't even crawl this content should it? . I guess the obvious answer is to only put each post in one category but I shouldn't have to should I? Some posts are relevant in more than once category.

Duplicate Content, Campaign Explorer & Rel Canonical
Google Advises to use Rel Canonical URL's to advise them which page with similiar information is more relevant. You are supposed to put a rel canonical on the non-preferred pages to point back to the desired page. How do you handle this with a product catalog using ajax, where the additional pages do not exist? An example would be: <colgroup><col width="470"></colgroup>

| .com/productcategory.aspx?page=1 /productcategory.aspx?page=2 /productcategory.aspx?page=3 /productcategory.aspx?page=4 The page=1,2,3 and 4 do not physically exist, they are simply referencing additional products I have rel canonical urls' on the main page www.examplesite.com/productcategory.aspx, but I am not 100% sure this is correct or how else it could be handled. Any Ideas Pro mozzers? |0
