      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 to fix non-crawlable pages affected by CSS modals?

                I stumbled across something new when doing a site audit in SEMRUSH today ---> Modals. The case: Several pages could not be crawled because of (modal:) in the URL. What I know: "A modal is a dialog box/popup window that is displayed on top of the current page" based on CSS and JS. What I don't know: How to prevent crawlers from finding them.

                Are pages not included in navigation given less "weight"

                Hi, we recently updated our website and our main navigation was dramatically slimmed down to just three pages and no drop down under those. Yet we have many more important pages, which are linked to once on one of those main three pages. However, will this hurt those other pages because they are not included in navigation (some of which were starting to get good traction in rankings)?
                Thanks!

                Reasons Why Our Website Pages Randomly Loads Without Content

                I know this is not a marketing question but this community is very dev savvy so I'm hoping someone can help me. At random times we're finding that our website pages load without the main body content. The header, footer and navigation loads just fine. If you refresh, it's fine but that's not a solution. Happens on Chrome, IE and Firefox, testing with multiple browser versions Happens across various page types - but seems to be only the main content section/container Happens while on the company network, as well as externally Happens after deleting cookies, temporary internet files and restarting computer We are using a CMS that is virtually unheard of - Bridgeline/Iapps Codebase is .net Our IT/Dev group keeps pushing back, blaming it on cookies or Chrome plugins because they apparently are unable to "recreate the problem". This has been going on for months and it's a terrible experience for the user to have. It's also not great when landing PPC visitors on pages that load with no content. If anyone has ideas as to why this may be happening I would really appreciate it. I'm not sure if links are allowed, by today the issue happened on this page serversdirect.com/dm/geek-biz Linking to an image example below knEUzqd

                How do I properly implement rel=me?

                Is there a primer anywhere that will help me understand how rel=me works and how to implement it properly? I do NOT have a blog but I do have a Google+ account. I want to put my mug into my SERPs so I need to understand both the concept and the technical details of implementing this. I am very comfortable with markup so I will be able to do this if I understand WHAT I am doing and HOW it is done. Thanks for your help! Chris Streeter

                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?

                Correct Canonical Reference

                Aloha, This is probably a noob question, but here we go: I got a CMS e-commerce, which does not allow static "rel=canonical" declaration in the header and can only work with third-party modules (xml packages) that append "rel=canonical" to all pages dynamic pages within the URL. As a result, I have pages I'm declaring incomplete rel="canonical" as such: Instead of: rel="canonical" src="www.domainname.com/category.aspx" I get: rel="canonical" src="/category.aspx" Coincidentally (or not), after the implementation of the canonical tag, pages that were continuously increasing in rankings started dropping, and, within a week, disappeared from the index completely. Could the drop be a result of my canonical links pointing to incomplete URLs? If so, by fixing this issue, do I stand a chance of recovering my pages' SERPs?

                Flat vs. Silo Site Architecture, What's Better

                I'm in the midst of converting a fairly large website (500+ pages) into WordPress as a content management system. I know that there are two schools of thought regarding site architecture: Those who believe that everything should be categorized, I.E.- website.com/shoes/reebok/running People who believe that the less clicks it takes from the homepage the better. As it stands, our current site has a completely flat architecture, with landing pages being added randomly to the root, I.E.- website.com/affordable-shoes-in-louisville-ky I'm beginning to think that there is a gray area with this. I spoke to someone who says that you should never have a page more than 2 categories/subfolders deep. But if we plan on adding a lot of content doesn't it make sense to set the site up into many categories so we can set a good foundation for adding massive amounts of content. Also, will 301 redirecting to the new structure cause us to lose rankings for certain terms? Any help here is appreciated.
