canonical can help sometimes but first a good structure to avoid uplicated content, relevance dispersion and internal link leaking http://dynamical.biz/blog/seo-content-optimization/web-structure-duplicate-content-canonical-12.html

Hi Matt,

I’m SEO specialist at the biggest auction site in CEE, I’ve got 2 questions about canoncial link which will help me a lot.

1. Can I use canonical for url’s with added affiliate ID from our Affiliate Program? (i.e. the url is http://site.com/computers.php&affiliateID=10 will it pass the SEO link juice to http://site.com/computers.php)?

2. Can I use canonical at url’s with ended auctions? (i.e. if an auction ends we’ll automaticly put canonical to parent category where this auction was?)

Thanks,
Bart

@Ian M Said, the Windows file system can set to case sensitive. See http://support.microsoft.com/kb/817921/ for details.

By the way, it’s not just IIS that has case-sensitivity issues – Apache on Windows has the same issue. It’s the case-insensitive Windows filesystem that’s the problem.

A couple questions for this example:

example.com/page1?page=3
example.com/page1?sortby_price_asc
example.com/page1?sortby_date_desc

all have cannoical link points to:
example.com/page1

1. Will Google eventually or quickly remove all pages with canonical link element but just keep the page the canonical link points to?

2. Will this hurt the pagerank of example.com/page1 since different variance with different sorting algorithm would have different unique nature such as keyword density. WIll example.com/page1 be able to have all those unique nature or G will just treat it based content on example.com/page1?

Hi Matt,

I noticed w3.org mentions the LINK element can be used to provide a variety of information to search engines. Besides “rel=canonical”, what other LINK element attributes does Google honor?

What are your thoughts on some of the examples given there?: http://www.w3.org/TR/html4/struct/links.html#h-12.3.3

Hi Matt,

We use “?example” to tag the links on our site so that we can get more info about where people are clicking when we view our site overlay on Google Analytics.

As a result, we have multiple URL’s linking to the same page:

http://www.example.com/about.htm?topnav
http://www.example.com/about.htm?midpage

and of course:

http://www.example.com/about.htm

Would this result in duplicate content issues? If so, is there a “best practice” to “tag” links for better site analysis in Google Analytic’s overlay?

Thanks in advance.

Tom

I just posted your YouTube video on my website and blog. You know, it might’ve been a long time before I heard about the Canonical Link Element, I’m glad I took the time to ‘play’ around online for once. I’m not sure how to go about ‘testing’ my site for duplicate URL content, but I added the link element to my blog and hopefully that will handle any major issues (if they were) or have arose.

Matt, the official syntax of this element generates an error message in BBEdit’s syntax checker when inserted into an HTML 4.01 document. I think you need to document that the final slash is only for XHTML. I haven’t seen that distinction made anywhere.
