          If a page is clearly unique and there is obviously no canonical tag needed, does it hurt anything if one has been added?

            In my opinion, you want the juice for each article to stay with each article.  I wouldn't redirect all your article juice back to the main /blog page.  For me, each unique page (and article) gets its own canonical link and one line = one set of information.  Article about oranges, article about apples, both canonical links.  You should only get juice from same or similar pages, such as

            yoursite.com/

            yoursite.com/index.php

            www.yoursite.com/index.php

            www.yoursite.com/

            But not

            yoursite.com/oranges/

              hey matt, thanks for the response.  let me ask you this.  i have a blog page with a bunch of snippets, that when clicked, lead to the full articles, (each have their own custom page/url).  if i want all the juice to go to the main blog page i don't want to have canonical tags on each individual post page, right?

                Agreed. You page can sometimes end up with query parameters as well when people link to your site, and having the canonical in place will help you avoid having duplicate content.

                  It shouldn't hurt you if it doesn't need it but assuming you have www and non-www, wouldn't that part of the canonical always help anyways?  By default, you would have

                  http://www.yoursite.com/notagneeded

                  http://yoursite.com/notagneeded

                  and if you're on most common CMSs,

                  http://www.yoursite.com/notagneeded/index.php or index.html or index.asp

                  It would actually be pretty rare to have a page with absolutely no use for rel=canonical but I don't see why it would hurt at all.

                    How is Single Page Application (SPA) bad for SEO

                    Hi guys. I am quite inspired of SPA technique. It's really amazing when all your interaction with the site is going on the fly and you don't see any page reloads. I've started implementing the site with this instruction and already found nice guys to make the design. The only downside of the using SPA which I can see **is the **SEO part. That's because the URL does not really change and different pages don't have their unique URL addresses. 
                    Actually they have, but it looks like: yoursite.com/#/products yoursite.com/#/prices yoursite.com/#/contact So all of them goes after # and being just anchors. For Google this mean all of these pages is just yoursite.com/ My question is what is really proven method to implement the URL structure in Single Page Application, so all the pages indexed by Google correctly (sorry I don't mention the other search engines because of market share). The other question, of course, is examples. It will be great to see real life site examples, better authority sites, which use SPA technique and well indexed by search engines.

                    Do we need both an .XML Sitemap and a .aspx sitemap?

                    Hi Mozers, We recently switched servers and it came to my attention that we have two sitemaps a XML version of the sitemap and a .aspx version of the sitemap. This came to light as the .aspx version of the sitemap is causing the site to come to a screeching halt as it has some complex code and lists over 80,000 products. My question is do we need both versions of the sitemap? My understanding is that the XML version is for Search Engine bots and the .aspx version is for customers. I can't imagine that anyone is using our .aspx version as it is basically a page with 80,000 links and it's buried away on the site, so we were hoping to kill off the .aspx version of the sitemap and keep the .xml version for Search Engine Bots. I wanted to check here first to make sure we did not any negative search engine implications. Any help would be most appreciated. Thanks so much! Patrick

                    Multi-page articles, pagination, best practice...

                    A couple months ago we mitigated a 12-year-old site -- about 2,000 pages -- to WordPress.
                    The transition was smooth (301 redirects), we haven't lost much search juice. We have about 75 multi-page articles (posts); we're using a plugin (Organize Series) to manage the pagination. On the old site, all of the pages in the series had the same title. I've since heard this is not a good SEO practice (duplicate titles). The url's were the same too, with a 'number' (designating the page number) appended to the title text. Here's my question: 1. Is there a best practice for titles & url's of multi-page articles? Let's say we have an article named: 'This is an Article' ... What if I name the pages like this:
                    -- This is an Article, Page 1
                    -- This is an Article, Page 2
                    -- This is an Article, Page 3 Is that a good idea? Or, should each page have a completely different title? Does it matter?
                    ** I think for usability, the examples above are best; they give the reader context. What about url's ?  Are these a good idea? /this-is-an-article-01,  /this-is-an-article-02, and so on...
                    Does it matter? 2. I've read that maybe multi-page articles are not such a good idea -- from usability and SEO standpoints. We tend to limit our articles to about 800 words per page.  So, is it better to publish 'long' articles instead of multi-page? Does it matter?  I think I'm seeing a trend on content sites toward long, one-page articles. 3. Any other gotchas we should be aware of, related to SEO/ multi-page? Long post... we've gone back-and-forth on this a couple times and need to get this settled.
                    Thanks much! Jim

                    Multiple Local Schemas Per Page

                    I am working on a mid size restaurant groups site.  The new site (in development) has a drop down of each of the locations.  When you hover over a location in the drop down it shows the businesses info (NAP).  Each of the location in the Nav list are using schema.org markup. I think this would be confusing for search robots.  Every page has 15 address schemas and individual restaurants pages NAP is at the below all the locations' schema/NAP in the DOM. Have any of you dealt with multiple schemas per page or similar structure?

                    Question on Breadcrumb and Canonical

                    Hi SEOmozers, I have another question.  =]  Thanks in  advance. First question: How important is the breadcrumb for SEO? I know that breadcrumb makes better UX because it shows how the visitor landed on this page and the breadcrumb may show up in the search engine.  But other than that, how important is it? Second Question: If I have a page that can be found via 2 locations, how should I handle this in regards to breadcrumb? For example, I have page A.  You can access page A via Category A and Category B.  Therefore, what I did was list Page A under Category A and when someone visit Category B and click on Page A, it will redirect to the page A that was found via Category A. The problem is on page A, the breadcrumb is Home > Category A > Page A.  So if someone visit Category B and click on Page A, it redirects and the breadcrumb shows Home > Category A > Page A. What should I do with the breadcrumb for Category B > Page A? Should I create another page A and just use canonical on it? Should I create another page A but do not index it? or leave it as is? 1 Page A, can be access via 2 categories. Please advise. Thank you!

                    How to put 'Link to this article' HTML code at bottom of article & is it helpful?

                    Hello, I was thinking about putting a box down at the bottom of my client's main articles that let's the reader easily copy the html code it takes to link to the article they're reading.  Maybe I'd put it after the author bio. Do any of you do this? If so, what format do you use? It has to look nice of course. This is a non-techie industry. Thanks.

                    How to Add canonical tags on .ASPX pages?

                    What is the proper way (or is it possible) to add canonical tags on website pages that end in .aspx? If you add a canonical tag to the Master Page it will put that exact canonical tag on every page, which is bad. Is there a different version of the tag to put on individual pages? And one to put on the home page without the Master Page error?
