      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.

                Have Your Thoughts Changed Regarding Canonical Tag Best Practice for Pagination? - Google Ignoring rel= Next/Prev Tagging

                Hi there, We have a good-sized eCommerce client that is gearing up for a relaunch. At this point, the staging site follows the previous best practice for pagination (self-referencing canonical tags on each page; rel=next & prev tags referencing the last and next page within the category). Knowing that Google does not support rel=next/prev tags, does that change your thoughts for how to set up canonical tags within a paginated product category? We have some categories that have 500-600 products so creating and canonicalizing to a 'view all' page is not ideal for us. That leaves us with the following options (feel it is worth noting that we are leaving rel=next / prev tags in place): Leave canonical tags as-is, page 2 of the product category will have a canonical tag referencing ?page=2 URL Reference Page 1 of product category on all pages within the category series, page 2 of product category would have canonical tag referencing page 1 (/category/) - this is admittedly what I am leaning toward. Any and all thoughts are appreciated! If this were in relation to an existing website that is not experiencing indexing issues, I wouldn't worry about these. Given we are launching a new site, now is the time to make such a change. Thank you! Joe

                One Page Guide vs. Multiple Individual Pages

                Howdy, Mozzers! I am having a battle with my inner-self regarding how to structure a resources section for our website. We're building out several pieces of content that are meant to be educational for our clients and I'm having trouble deciding how to layout the content structure. We could either layout all eight short sections on a single page, or create individual pages for each section. The goal is obviously to attract new potential clients by targeting these terms that they may be searching for in an information gathering stage. Here's my dilemma...
                With the single page guide, it would be nice because it will have a lot of content (and of course, keywords) to be picked up by the SERPS but I worry that it is going to be a bit crammed (because of eight sections) for the user. The individual pages would be much better organized and you can target more specific keywords, but I worry that it may get flagged for light content as some pages may have as little as a 150 word description. I have always been mindful of writing copy for searchers over spiders, but now I'm at a more technical crossroads as far as potentially getting dinged for not having robust content on each page. Here's where you come in...
                What do you think is the better of the two options? I like the idea of having the multiple pages because of the ability to hone-in on a keyword and the clean, organized feel, but I worry about the lack of content (and possibly losing out on long-tail opportunities). I'd love to hear your thoughts. Please and thank you. Ready annnnnnnnnnnnd GO!

                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...

                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!

                Landing pages vs internal pages.

                Hey everyone I have run into a problem and would greatly appreciate anyone that could weigh in on it. I have a web client that went to an outside vendor for marketing. The client asked me to help them target some keywords and since I am new to the SEO world I have proceeded by researching the best keywords for the client. I found 6 that see excellent monthly searches. I then registered the .com and or .net domain names that match these words. I then started building landing pages that make reference to the keyword and then have links to his site to get more info. My customer sent the first of these sites to the marketer and he says I am doing things all wrong. He says rather then having landing pages like this I should just point the domain names at internal pages to the website. He also says that I should not have different looks for the landing pages from the main site and that I should have the full site menu on each landing page. I wanted to here what everyone here has to say about the pros and cons of the way to do this cause the guy giving the advice to me has a lower ranking site then I do and I have only started working on getting my site ranked this year. He has atleast according to him been doing this forever. Thanks, Ron

                Is it necessary to redirect every Error page (404 or 500) found?

                If I have Hundreds of pages with 404 and 500 erros should set up 301 redirects for all of them?  Some of the pages have external links, some don't.

                Custom URL's with Bigcommerce Issue (Is it worth it?)

                We're building out a store in Bigcommerce, who for all intensive purposes is perfect for SEO besides the fact that you can not change the URL's to be custom. My question is, does this kill the SEO value of bigcommerce, despite everything else being great? So for example the URL's for a category page would be something like this www.mysite.com/categories/keyword and the product URL's are pulled in by product name, so product URL's could be something like www.mysite.com/products/Product-Description-Long-223.html (notice the words will be capitalized and their is no way to remove the trailing .html) I could go with Interspire (the liscenced version of Bigcommerce) or Magento so I can custom edit this stuff. But then its a lot more work for my employee's on the buildout.
