      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.

                Homepage Slider How to Handle H1 and H2's

                Working on a site with a slider on the homepage, I dislike them but owner wants to keep in place. Currently, the slider has 4 slides with different images but the same text, so the slider has 4 slides with 4 identical H2 tags and accompanying text. There is no H1 tag on the page at all. It seems to me that a better solution would be to change the first slide to be H1 (with the target keyword) and rework the text in the other slides as H2 tags to appeal to the user. This does mean that the H1 and H2 tags in the slider would be styled the same. Is this a sensible approach?

                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.

                Dead end pages are really an issue?

                Hi all, We have many pages which are help guides to our features. These pages do not have anymore outgoing links (internal / external). We haven't linked as these are already 4th level pages and specific about particular topic. So these are technically dead end pages. Do these pages really hurt us? We need to link to some other pages? Thanks

                Incorporating Spanish Page/Site

                We bought an exact match domain (in Spanish) to incorporate with regular website for a particular keyword. This is our first attempt at this, and while we do have Spanish speaking staff that will translate/create a nice, quality page, we're not going to redo everything in Spanish page. Any advice on how to implement this? Do I need to create a whole other website in Spanish? Will that be duplicate content if I do? Can I just set it up to show the first page in Spanish, but if they click on anything else it redirects to our site? I'm pretty clueless on this, so if anything I've suggested is off-the-wall or a violation, I'm really just spit-balling, trying to figure out how to implement this. Thanks, Ruben

                Too Many Outbound Links on the Home Page - Bad for SEO?

                Hello Again Moz community, This is my last Q of the day: I have a LOT of outbound links on the home page of www.web3.ca Some are to clients projects, most are to other pages on the website. Can reducing this to the core pages have a positive impact on SEO? Thanks, Anton

                How to make sure category pages rank higher than product pages?

                Hi, This question is E-Commerce related. We have product categories dividing products by color. Let's say we have the category 'blue toy cars' and a product called 'blue toy car racer', both of these could rank for the keyword 'blue toy car'. How do we make sure the category 'blue toy cars' ranks above the product 'blue toy car racer'? Or is the category page automatically ranked higher because of the higher page authority of that page? Alex

                Other tags inside an H1 tag

                So I have a situation with the website I'm currently redesigning where the H1 titles are supposed to mix colors per the current brand strategy. The branding crew is adamant that this has to be done so there is no use in saying "just don't do it". To accomplish this I'm wrapping the words that need to be the other color in a . Additionally, some pages have a "sub text" as part of the title, floated to the right and in a smaller font but with the same multi color treatment. I'm wondering if the sub text should be in an H2 and positioned to the right or if it would be beneficial to have the text in the H1 as well. An example of what I'm talking about would be something like this: "Big Shoes for Big Guys - Nike Shoes" In that, the "Big Shoes" and "Nike" would be one color and the "for Big Guys" and "Shoes" would be another. I can imagine having the "Nike Shoes" as part of the H1 would be a good idea in some respect but I'm not certain of that. In order to make that happen I can only think of one way to do it: -H1-
                Big Shoes
                -span- for Big Guys -/span-
                -div- Nike
                -span- Shoes -/span-
                -/div-
                -/H1- So that brings me back to the original concern, do search engines care about tags inside the H1? The only other way to accomplish the color changes that I can think of would be to have a fairly large chunk of javascript setup to go through H1's to colorize them using the span tags. That is unless GoogleBot has started to execute javascript while crawling the sites now...

                What else should you call the Home page?

                In the menu bar and footer the main page is called Home.  Would it confuse people to rename it to Business Name Home or Business Name? How do you handle this?
