How can you manually diagnose the canonical problem
-
Good Monrning from snow dusted minus 3 degrees C Wetherby UK...
Is there a quick way to diagnose wether or not a website has a canonical problem or not?
So far Ive been doing this for example: Typing a full web address then one without the w's and seeing if a 301 redirect has been set up. But I'm not confident this is the best way to diagnose if there is a canonical problem with a site.
I would like to ad that I want to see if a canonical problem exists with any site and webmanster tools is not available.
Any insights welcome

A suggestion that all major search engines obey. We used it massively and it is 100% listened to by search engines.

Keep in mind that rel=canonical is more of a suggestion than a command.

Hey Nightwing
I think you need to be careful here. A 301 is a re-direct whereas a canonical is telling Google, Bing etc to treat this page as a duplicate and not index it.
To quote Google: "A canonical page is the preferred version of a set of pages with highly similar content."
See Matt Cutts and all his beauty explain here: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=139394
A canonical won't re-direct the page like a 301, the page still exists, it's just that search engines will remove it from SERPs.
As long as the code is all set up right, the only way to check for a canonical is working is to review the code.....and it should also drop out of the SERPs too.
Hope this helps.

Morning Nightwing
We also had some snow here in B'ham but it's almost gone now.
If you want to be sure then simply implement 301 redirects. When doing a manual check, like the one you've mentioned above, you can look at your SEOmoz toolbar and you will often see a difference in PA of different versions of your page.

Use screaming frog.
Using the free version it will crawl up to 500 pages. For each page it will then provide the status code i.e. 302, 400 e.t.c That way you can determine if there are any page issues.
In general, Google Webmaster Tools is your best bet of showing a sites cannonical issues. Otherwise you can also try SEOMoz's pro tools ;0
Hope this helps.

Having Problems to Index all URLs on Sitemap
Hi all again ! Thanks in advance ! My client's site is having problems to index all its pages. I even bought the full extension of XML Sitemaps and the number of urls increased, but we still have problems to index all of them. What are the reasons? The robots.txt is open for all robots, we only prohibit users and spiders to enter our Intranet. I've read that duplicate content and 404's can be the reason. Anything else?

Can Anybody Understand This ?
Hey guyz,
Technical SEO | | atakala
These days I'm reading the paperwork from sergey brin and larry which is the first paper of Google.
And I dont get the Ranking part which is: "Google maintains much more information about web documents than typical search engines. Every hitlist includes position, font, and capitalization information. Additionally, we factor in hits from anchor text and the PageRank of the document. Combining all of this information into a rank is difficult. We designed our ranking function so that no particular factor can have too much influence. First, consider the simplest case -- a single word query. In order to rank a document with a single word query, Google looks at that document's hit list for that word. Google considers each hit to be one of several different types (title, anchor, URL, plain text large font, plain text small font, ...), each of which has its own type-weight. The type-weights make up a vector indexed by type. Google counts the number of hits of each type in the hit list. Then every count is converted into a count-weight. Count-weights increase linearly with counts at first but quickly taper off so that more than a certain count will not help. We take the dot product of the vector of count-weights with the vector of type-weights to compute an IR score for the document. Finally, the IR score is combined with PageRank to give a final rank to the document. For a multi-word search, the situation is more complicated. Now multiple hit lists must be scanned through at once so that hits occurring close together in a document are weighted higher than hits occurring far apart. The hits from the multiple hit lists are matched up so that nearby hits are matched together. For every matched set of hits, a proximity is computed. The proximity is based on how far apart the hits are in the document (or anchor) but is classified into 10 different value "bins" ranging from a phrase match to "not even close". Counts are computed not only for every type of hit but for every type and proximity. Every type and proximity pair has a type-prox-weight. The counts are converted into count-weights and we take the dot product of the count-weights and the type-prox-weights to compute an IR score. All of these numbers and matrices can all be displayed with the search results using a special debug mode. These displays have been very helpful in developing the ranking system. "0 -

Canonical versus 301 for affilaite links
Affiliate links for the Volusion ecommerce shops are of the form mydomain.com/?Click=XX where XX is the affiliate ID. Volusion uses rel=canonical to redirect the affiliate links to mydomain.com. Is this a good solution? I used iDevAffiliate for another online store, and their solution was to use 301 redirects to trip off the ? string. Comments? Best,
