How much (%) of the content of a page is considered too much duplication?
-
Google is not fond of duplication, I have been very kindly told. So how much would you suggest is too much?
-
I would not use a canonnical for your www v non www, use a 301
there is a tutorial there also to fix the index.html problem also, these tutorials are for micdrosoft iis server, if you have linux, you need to find the htaccess alternatives.
I always go for the non www, as www is of no use, so why have it, but for you i would look at what your links point to.

Hi Alan
Thankyou for taking the time to offer advice to me. I have read your pages and it does raise some interesting points. One that although basic, is one I haven't yet paid much attention to is the issue of "The choice of www or non-www".
This is interesting in respect of how I set my canonical tags up. I noticed that I rank differently for www.waspkilluk.co.uk than for www.waspkilluk.co.uk/index. So it seems I need to add a canonical tag there. I guess index is my home page - but then isn't the root domain also my default homepage?
In fact - do you think you should set up canonical tags without the www. or won't this work?
Sorry for creating questions from questions.
Warm Regards
Simon

Hi James
I have had a thorough study of this issue today and your ideas have proved fruitful. I checked out the article by Matt Cutts http://www.mattcutts.com/blog/canonical-link-tag/ and then read the article by Rand Fishkin. http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps.
it will take a few weeks to implement across the thousand or so pages I have, but it will be interesting to see how or if, it finally affects the root domains ranking.
Many thanks
Simon

James gives a good response.
i have a few tutorial pages, where a lot of the instuctions are the same, but the are still indexed and rank.
It maybe a guide of what you can get a way with

It is hard to give an accurate percentage, in my eyes if you want to be in the clear just make unique content on pages if it is not unique content then place a canonical tag to the right page.
I mean Google is coming down harder and harder on sites for poor quality content/duplicant content if you play by the rules and do things right tit will be a long term strategy.

Help with duplicate pages
Hi there, I have a client who's site I am currently reviewing prior to a SEO campaign. They still work with the development team who built the site (not my company). I have discovered 311 instances of duplicate content within the crawl report. The duplicate content appears to either be 1, 2, or 3 versions of the same pages but with differing URL's. Example: http://www.sitename.com http://sitename.com http://sitename.com/index.php And other pages follow a similar or same pattern. I suppose my question is mainly what could be causing this and how can I fix it? Or, is it something that will have to be fixed by the website developers? Thanks in advance Darren

Duplicate Multi-site Content, Duplicate URLs
We have 2 ecommerce sites that are 95% identical. Both sites carry the same 2000 products, and for the most part, have the identical product descriptions. They both have a lot of branded search, and a considerable amount of domain authority. We are in the process of changing out product descriptions so that they are unique. Certain categories of products rank better on one site than another. When we've deployed unique product descriptions on both sites, we've been able to get some double listings on Page 1 of the SERPs. The categories on the sites have different names, and our URL structure is www.domain.com/category-name/sub-category-name/product-name.cfm. So even though the product names are the same, the URLs are different including the category names. We are in the process of flattening our URL structures, eliminating the category and subcategory names from the product URLs: www.domain.com/product-name.cfm. The upshot is that the product URLs will be the same. Is that going to cause us any ranking issues?

Duplicate content - how to diagnose duplicate content from another domain before publishing pages?
Hi, 🙂 My company is having new distributor contract, and we are starting to sell products on our own webshop. Bio-technology is an industry in question and over 1.000 products. Writing product description from scratch would take many hours. The plan is to re-write it. With permission from our contractors we will import their 'product description' on our webshop. But, I am concerned being penalies from Google for duplicate content. If we re-write it we should be fine i guess. But, how can we be sure? Is there any good tool for comparing only text (because i don't want to publish the pages to compare URLs)? What else should we be aware off beside checking 'product description' for duplicate content? Duplicate content is big issue for all of us, i hope this answers will be helpful for many of us. Keep it hard work and thank you very much for your answers, Cheers, Dusan

Duplicate content question
Hi there, I work for a Theater news site. We have an issue where our system creates a chunk of duplicate content in Google's eyes and we're not sure how best to solve. When an editor produces a video, it simultaneously 1) creates a page with it's own static URL (e.g. http://www.theatermania.com/video/mary-louise-parker-tommy-tune-laura-osnes-and-more_668.html); and 2) displays said video on a public index page (http://www.theatermania.com/videos/). Since the content is very similar, Google sees them as duplicate. What should we do about this? We were thinking that one solution would to be dynamically canonicalize the index page to the static page whenever a new video is posted, but would Google frown on this? Alternatively, should we simply nofollow the index page? Lastly, are there any solutions we may have missed entirely?

Can PDF be seen as duplicate content? If so, how to prevent it?
I see no reason why PDF couldn't be considered duplicate content but I haven't seen any threads about it. We publish loads of product documentation provided by manufacturers as well as White Papers and Case Studies. These give our customers and prospects a better idea off our solutions and help them along their buying process. However, I'm not sure if it would be better to make them non-indexable to prevent duplicate content issues. Clearly we would prefer a solutions where we benefit from to keywords in the documents. Any one has insight on how to deal with PDF provided by third parties? Thanks in advance.

Redirecting One Page of Content on Domain A to Domain B
Let's say I have a nice page of content on Domain A, which is a strong domain. That page has a nice number of links from other websites and ranks on the first page of the SERPs for some good keywords. However, I would like to move that single page of content to Domain B using a 301 redirect. Domain B is a slightly weaker domain, however, it has better assets to monetize the traffic that visits this page of content. I expect that the rankings might slip down a few places but I am hoping that I will at least keep some of the credit for the inbound links from other websites. Has anyone ever done this? Did it work as you expected? Did the content hold its rankings after being moved? Any advice or philosophical opinions on this? Thank you!

Duplicate Content from Article Directories
I have a small client with a website PR2, 268 links from 21 root domains with mozTrusts 5.5, MozRank 4.5 However whenever I check in google for the amount of link: Google always give the response none. My client has a blog and many articles on the blog. However they have submitted their blog article every time to article directories as well, plain and simle creating duplicate and content. Is this the reason why their link: is coming up as none? Is there something to correct the situation?
