      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

                Should i be using shortcodes for my my page content.

                Hello, I have a question. Sorry if this is been answered before. Recently I decided to do a little face lift to my main website pages. I wanted to make my testimonials more pretty. Found this great plugin for testimonials which creates shortcodes. I love how it looks like, but just realised that when I use images in shortcodes, these are not picked up by search engines 😞 only text is. Image search ability is pretty important for me and I'm not sure if I should stick with my plain design and upload images manually with all alt tags and title tags or there is a way to adjust shortcode so it shows images to search engines. You can see example here. https://a-fotografy.co.uk/maternity-photographer-edinburgh/ Let me know your thoughts guys. Regards, Armands

                Bing Indexation and handling of X-ROBOTS tag or AngularJS

                Hi MozCommunity, I have been tearing my hair out trying to figure out why BING wont index a test site we're running. We're in the midst of upgrading one of our sites from archaic technology and infrastructure to a fully responsive version.
                This new site is a fully AngularJS driven site. There's currently over 2 million pages and as we're developing the new site in the backend, we would like to test out the tech with Google and Bing. We're looking at a pre-render option to be able to create static HTML snapshots of the pages that we care about the most and will be available on the sitemap.xml.gz However, with 3 completely static HTML control pages established, where we had a page with no robots metatag on the page, one with the robots NOINDEX metatag in the head section and one with a dynamic header (X-ROBOTS meta) on a third page with the NOINDEX directive as well. We expected the one without the meta tag to at least get indexed along with the homepage of the test site. In addition to those 3 control pages, we had 3 pages where we had an internal search results page with the dynamic NOINDEX header. A listing page with no such header and the homepage with no such header. With Google, the correct indexation occured with only 3 pages being indexed, being the homepage, the listing page and the control page without the metatag. However, with BING, there's nothing. No page indexed at all. Not even the flat static HTML page without any robots directive. I have a valid sitemap.xml file and a robots.txt directive open to all engines across all pages yet, nothing. I used the fetch as Bingbot tool, the SEO analyzer Tool and the Preview Page Tool within Bing Webmaster Tools, and they all show a preview of the requested pages. Including the ones with the dynamic header asking it not to index those pages. I'm stumped. I don't know what to do next to understand if BING can accurately process dynamic headers or AngularJS content. Upon checking BWT, there's definitely been crawl activity since it marked against the XML sitemap as successful and put a 4 next to the number of crawled pages. Still no result when running a site: command though. Google responded perfectly and understood exactly which pages to index and crawl. Anyone else used dynamic headers or AngularJS that might be able to chime in perhaps with running similar tests? Thanks in advance for your assistance....

                2 Menu links to same page. Is this a problem?

                One of my clients wants to link to the same page from several places in the navigation menu. Does this create any crawl issues or indexing problems? It's the same page (same url) so there is no duplicate content problems. Since the page is promotional, the client wants the page accessible from different places in the nav bar. Thanks, Dino

                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...

                Custom 404 Page Indexing

                Hi - We created a custom 404 page based on SEOMoz recommendations.  But.... the page seems to be receiving traffic via organic search.  Does it make more sense to set this page as "noindex" by its metatag?

                Site-wide footer links or single "website credits" page?

                I see that you have already answered this question before back in 2007 (http://www.seomoz.org/qa/view/2163), but wanted to ask your current opinion on the same question: Should I add a site-wide footer link to my client websites pointing to my website, or should I create a "website credits" page on my clients site, add this to the footer and then link from within this page out to my website?
