Hi Guy,
Does this help...
Although the canonical URL tag is generally thought of as a way to solve duplicate content problems, it can be extremely wise to use it on every (unique) page of a site to help prevent any query strings, session IDs, scraped versions, licensing deals or future developments to potentially create a secondary version and pull link juice or other metrics away from the original. We believe the canonical URL tag is a best practice to help prevent future problems, even if nothing is specifically duplicate/problematic today.

Is putting a manufacturer's product manual on my site in PDF duplicate content
I add the product manuals to our product pages to provide additional product information to our customers. Is this considered duplicate content? Is there a best way to do this so that I can offer the information to my customers without getting penalized for it? Should they be indexable? If not how do I control?

Duplicate Content
Hi, I'm working on a site and I'm having some issues with its structure causing duplicate content. The first issue is that the search pages will show up as duplicates.
Technical SEO | | OOMDODigital
A search for new inventory may be new.aspx
The duplicate may be something like new.aspx=page1, or something like that and so on. The second issue is with inventory. When new inventory gets put into the stock of the store, a new page for that item will be populated with duplicate content. There appears to be no canonical source for that page. How can I fix both of these? Thanks!0 -
Canonical warnings
[1] My site development tool (XSP) has recently added the canonical reference as an auto-generated tag, so every page of my site now has it. Why is SEOmoz warning me that I have hundreds of pages of canonicals if it's supposed to be a GOOD thing? [2] Google is still seeing the pages without the canonical tag because that's how they were indexed. Will they eventually get purged from their index, or should I be proactive about that, and if so, how? Thanks for any input.

Redirecting a old aged site to a new exact match site?
Hi All, I have a question. I have 2 sites with me in the same sector and want some help. site 1 is a old site started back in 2003 and has some amount of links to it and has a pr 3 with some good links to it but doesn't rank much for any keywords for the timing. site 2 is a aged domain but newly developed with unique content and has a good amount of exact match with a .com version. so will there be any benefit by redirecting site 1 to site 2 to get the seo benefits and a start for link bulding? or is it best to develop and work on each site? the sector is health insurance. Thanks

Duplicate Content Issues - Should I build a new site?
I'm currently working on a site which is built using Zen Cart. The client also has another version which has the same products on it. The product descriptions and the vast majority of the text has been re-written. I've used the duplicate content tool and these are the results: HTML fingerprint: 0000a7ee1f07a131 0000a7ec1f07a931 92.31% Total HTML similarity: 76.33% Standard text similarity: 66.72% Smart text similarity: 45.81% Total text similarity 56.27% I considered using a different eCommerce system like Magento or Volusion. So I had a look at a few templates, chose one and then used the tool again and got the following: HTML fingerprint: 0000a7e41b012111 0000a7ec1f07a931 72.00% Total HTML similarity: 64.65% Standard text similarity: 11.69% Smart text similarity: 17.90% Total text similarity 14.80% Do you think its worth doing this? thanks Dan

Can I use canonical tags to merge property map pages and availability pages to their counterpart overview pages?
I have a property website, for each property are 4-5 tabs each with their own URL, these pages include the overview page which is content rich, and auxilliary pages such as maps, availability, can I use a canonical tag to merge the tabs with very little content to their corresponding overview page which is content rich? I.e. www.mywebsite.co.uk/property-1/overview This page has tabs for map, town info, availability which all have their own url i.e. www.mywebsite.co.uk/property-1/map

www.mywebsite.co.uk/property-1/availability
www.mywebsite.co.uk/property-1/towninfo Because these auxilary pages do not contain much content can I place a canonical tag in them pointing back to the content rich overview page at www.mywebsite.co.uk/property-1/overview?0 -
Canonical on ecommerce site
I have read tons of guides about canonical implementaiton but still am confused about how I should best use it. On my site with tens of thousands of urls and thousands of afiiliates and shopping networks sending traffic, is it smart to simply add the tag to every page and redirect to the same url. In doing this would that solve the problem of a single page having many different entrances with different tracking codes? Is there a better way to handle this? Also is there any potential problems with rolling out the tag to all pages if they are simply refrencing themselves in the tag? Thanks in advance.
