Canonical tag question
-
Suppose a site has two pages ( Page A ) and Page B. Both of them have pagerank, but duplicate content.
The page A is ranked for keyword "seo india" and page B is ranked for keyword "seo services".
If i implement canonical tag on page B, does
1. The pagerank of page B will be transfered to Page A ?
2. Does the site A now ranks for keyword "seo servicies " ( for which Page B was ranking earlier )
-
Google views the canonical tag as a hint, and reserves the right to ignore it if the pages don't look to be virtually identical in content, so it would depend in part on how much of the content is duplicate. If it's your own site, you can always give it a try and see. If it's a client site and they're depending on both pages ranking for conversions, I'd warn them first that you might lose the rankings from Page B.

I would agree with Stephen on point 1, but would throw the following thoughts in on point 2:
For example:
page A is mysite.com/seo-india
page B is mysite.com/seo-services
I would guess that there would be a minor difference in ranking impact on a couple of counts with respect to what phrase is ranked for in each case - despite having the same content.
Things to consider would be the url itself, the page title, the H1 and the metadescription.
I can't see that using a canon from one page to another will migrate additional ranking terms to the destination page in its own right - if you have links to page B with anchors that reflect the terms it might - but how long you would continue to rank for the additional term would be questionable.
If it was that simple to get the same page to rank for multiple terms just by duplicating content, linking to it, and then redirecting with the canon tag - I am sure google would get wise to that pretty quick, and there would be no end of "top secret ranking" mails doing the rounds from "SEO gurus"
Would be interesting to test though!

I am not sure if there is just a simple yes or no answer to your questions. It is hard to predict exactly to what the search engines will do and ranking will change.
1. It looks like the answer to this question is Yes. Here is a snippet for a Google Webmaster Blog article.
Additional URL properties, like PageRank and related signals, are transferred as well.
2. I can only assume the answer to this question would be yes too. I would assume that since both pages are identical and are on the same domain, page A would now rank the same as page B. It is hard to know for sure though. Sorry I can't be more definitive but Google is a complex animal.

Migration developer question
Hi Guys, We are in the process of migrating our website and are moving to: AWS/Elastic Beanstalk hosting and the only way to do a custom domain with a third-party (not Amazon) DNS Service is by setting up a CNAME that points to the EBS Instance. Do you think this will impact SEO performance in any way? Cheers.

Robots.txt question
I notice something weird in Google robots. txt tester I have this line Disallow: display= in my robots.text but whatever URL I give to test it says blocked and shows this line in robots.text for example this line is to block pages like http://www.abc.com/lamps/floorlamps?display=table but if I test http://www.abc.com/lamps/floorlamps or any page it shows as blocked due to Disallow: display= am I doing something wrong or Google is just acting strange? I don't think pages with no display= are blocked in real.

Canonical tag
Hi all, I have an ecommerce client and on the pages they have a drop down so customers can view via price, list etc. Natrurally I want a canonical tag on these pages, here's the question. as they have different pages of products, the canonical tag on http://www.thegreatgiftcompany.com/occassion/christmas#items-/occassion/christmas/page=7/?sort=price_asc,searchterm=,layout=grid,page=1 is to http://www.thegreatgiftcompany.com/occassion/christmas#items-/occassion/christmas/page=7. now, because the page=7 is a duplicate of the main page, shouldn't the canonical just be to the main page rather than page=7? Even when there is a canonical tag on the /Christmas/page=7 to the /Christmas page? hope that makes sense to everyone!

Affiliate & canonicals
Hi, any help with this one would be great.... www.example.com sells widgets online. They are also promoted on a 3rd party website www.partner.com. Currently www.partner.com links to a page on www.example.com that is completely branded with the 'partners' design, style and unique copy (you would think you were still on 'partner' website). I saw this interesting article from 2011: http://www.seomoz.org/blog/getting-seo-value-from-your-affiliate-links (in particular idea 1) Do you think adding a rel=canonical on www.example.com's partner page is still safe? All the best & thank you, Richard

Canonical URLs and Sitemaps
We are using canonical link tags for product pages in a scenario where the URLs on the site contain category names, and the canonical URL points to a URL which does not contain the category names. So, the product page on the site is like www.example.com/clothes/skirts/skater-skirt-12345, and also like www.example.com/sale/clearance/skater-skirt-12345 in another category. And on both of these pages, the canonical link tag references a 3rd URL like www.example.com/skater-skirt-12345. This 3rd URL, used in the canonical link tag is a valid page, and displays the same content as the other two versions, but there are no actual links to this generic version anywhere on the site (nor external). Questions: 1. Does the generic URL referenced in the canonical link also need to be included as on-page links somewhere in the crawled navigation of the site, or is it okay to be just a valid URL not linked anywhere except for the canonical tags? 2. In our sitemap, is it okay to reference the non-canonical URLs, or does the sitemap have to reference only the canonical URL? In our case, the sitemap points to yet a 3rd variation of the URL, like www.example.com/product.jsp?productID=12345. This page retrieves the same content as the others, and includes a canonical link tag back to www.example.com/skater-skirt-12345. Is this a valid approach, or should we revise the sitemap to point to either the category-specific links or the canonical links?

Is this structure valid for a canonical tag?
Working on a site, and noticed their canonical tags follow the structure: //www.domain.com/article They cited their reason for this as http://www.ietf.org/rfc/rfc3986.txt. Does anyone know if Google will recognize this as a valid canonical? Are there any issues with using this as a the canonical?

Duplicate Content Question
My client's website is for an organization that is part of a larger organization - which has it's own website. We were given permission to use content from the larger organization's site on my client's redesigned site. The SEs will deem this as duplicate content, right? I can "re-write" the content for the new site, but it will still be closely based on the original content from the larger organization's site, due to the scientific/medical nature of the subject material. Is there a way around this dilemma so I do not get penalized? Thanks!

Ask a Question
We use DNN and we have case studies ran from our CMS. This is so we can have them in lists by category on service/market pages and show specific ones when needed. Then there is the case study detail page, (this is where the problem exists)to where you read out the case study in full detail and see the images and story. We enter our Case Studies into the CMS and this determines which website they show, and it creates URLs from the titles. However, on the detail page, the case studies all share the same page, Case Study.aspx, and they resolve to that page with their respected URLs in place. As seen here, http://www.structural.net/case-study/1/new-marlins-stadium.aspx Because they all share the same page they are being pulled as duplicate pages. They do show in the SERPS with the right title and URL and it all looks great, but they get errors for having duplicate page content and titles. Is there a way to solve this, or is this something I should even worry about?
