Recommendation: Add a canonical URL tag referencing this URL to the header of the page.
-
Please clarify:
In the page optimization tool, seomoz recommends using the canonical url tag on the unique page itself.
Is it the same canonical url tag used when want juice to go to the original page?
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.
Please give example.

Just to confirm please please as I am little confused after my On page report
If a I have a page name eg "http://www.ilovetravel/destinations/cruise/asia-river-cruises/"
do I need to add a canonical url tag to the header of my page
-
Hah! Really good point! Love it.
Stupid scrapers.

I totally agree with Paul.
Another thing I noticed on one of my websites: I had the canonical code in the header. Someone copied my entire page and published it to their website (with canonical tag) so the openly told the search engines that my website was the original copy of the content.
another reason why it could work

Probably the best concrete example of why this recommendation is valuable is when using Google Analytics campaign variables to point to landing pages.
Say your regular website page is www.mysite.com/mylanding page.html. On that page, you place the canonical tag in the header pointing back at itself.
It seems redundant until you realize that in future, you might very well be linking back to that page from a social media post or banner ad using Google Analytics tracking parameters. So the page would now be indexed under the url www.mysite.com/mylanding page.htm?utm_source=facebook&utm_medium=timeline-post&utm_campaign=mycampaign.
Google would see that new URL as a completely different page due to the extra parameters, but it would still have the canonical in the header pointing back to the plain version of the page URL, you would avoid duplicate content issues and splitting of page authority.
This demonstrates how the canonical tag can help prevent future problems even if it's not essential right now.
Make sense?

Example:
The page has a rel=canonical pointing to itself. That is what the tool recommeds.
The page still has a canonical tag pointing to the preferred URL.

Will canonical tag on non-copy content harm my site?
Days ago I added rel=canonical tags on my site. For the post pages, I add canonical tag on both post page (www.exmample.com/post.html) and comment page (www.exmample.com/post-sms.html), all the canonical tags are pointing to post page, but in fact there are only comments on the comment page. For product pages, I add the canonical tags on both product info page, download page, and order page, all of them are pointing to the info page, while in fact they are displaying different content. I no-indexed the comment page, download page, and order page for a long time. After I added the canonical tags, the traffics dropped (not hugely but slowly and steadily). Are my actions harming my site? Is this a normal flux after adding codes to the entire site, or it's the bad outcome for wrong SEO actions? PS: I can't change the site structure, so it's not possible to combine post and comment pages into one, so do the product pages. Thank you guys

Would I be safe canonicalizing comments pages on the first page?
We are building comment pages for an article site that live on a separate URL from the article (I know this is not ideal, but it is necessary). Each comments page will have a summary of the article at the top. Would I be safe using the first page of comments as the canonical URL for all subsequent comment pages? Or could I get away with using the actual article page as the canonical URL for all comment pages?

Keyword in URL
Hi everyone, I've heard many times that keyword prominence in url have a good impact for on-page optimization, even in SEOmoz it is one of the on-page factors. But what if i put keyword in URL then some of the page weight will be targeted to the page in the URL. Which in my vision makes only a negative impact. For ex. Targeted page <a>with keyword "buy car in NY" has a link with anchor text "buy car in NY" pointing on page **, so some weight from A will be transferred to B. Also I think this subject cover a cross linking, so I would like to know, what is the right way of doing cross linking and does it still brings any impact on keyword rankings in SERP.**</a> <a>**Good answer will be appreciated. Cheers, Russel**</a>

Do product pages need unique content or does having duplcate content hurt on those pages?
We are adding product rapidly to our website but this requires allowing duplicate to exist on our product pages of furniture-online.com. From an SEO standpoint do we need to make this content unique for each product. Since we aren't link building to specific product pages and we don't anticipate product pages being found in a search result, are we ok leaving the duplicate content in place and spending our dollars elsewhere?
