      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.

                Moving pages to new domain

                Hello, Our product pages are ranked #1 on google for our target keywords using our domain e.g. www.olddomain.com/cases/productxyz and sell about 20 products all ranked #1. We have a new company called www.newco.com/case/product1, 2, 3 etc. We use woocommerce e-commerce for both old and new sites. What is the best way to list our old co-products on our new site and move over the #1 rankings? Do we create new products (using our new nice design) in the newco.com woo commerce and then redirect old co links? do we copy and paste all that old content into the newco.com? Totally confused. Thank you!

                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

                Is having a site map page necessary?

                Hello all! So I know having a sitemap XML file is important to include in your robots.txt file.  I also know it is important to submit your XML sitemap to Google and Bing.  However, I am wondering if it is beneficial for your site's SEO value to have a sitemap page displayed on your website? Or is this just a redundant action if you have already done the above two actions with your XML sitemap? Thanks in advance!

                Is The HREF Link "Title" Tag Needed on Mobile Websites?

                Hello To Those Who Are Wiser Than I, I am wondering if the href link "title" tag is needed, or serves any purpose, on mobile websites?  Also, does it effect SEO in any way? I ask because generally the href link title tag provides more information to the user when they scroll their mouse over the link - but this action does not happen on mobile!  Users have no mouse and thus no extra information would be displayed. I'm really wondering if it still matters for SEO purposes on mobile though. -The UnEnlightened

                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!

                Body of text on category pages

                Hello everyone, wonder if I can pick your brains about our company's website. We are a tea company - Canton Tea Co. We have been advised that it is really important to get more text onto the category pages on our website, as otherwise the page just consists of a list of products, and therefore provides Google with a ton of headers, tiny descriptions, and not enough text to allow the page to being easily indexed, therefore hurting our Google ranking for key search terms like 'Green Tea' which should lead to the Green Tea category page. So we decided to add some text to the category page. The only place for this text to go was laid over the category header image. However, it looks pretty awful and unsophisticated having this text on top of the image - please see an example, our Green Tea category page, via this link: http://www.cantonteaco.com/loose-leaf-tea-1/type/green-tea.html So I have three questions: How significant is the text on a category page such as this to that page's Google ranking? If we moved the text to an area that was hidden until clicked on, for example the 'Filter by' section that opens up when you click on it (see via URL above), would that negate the SEO benefit? Do you have any other ideas or opinions on how to resolve this? Thank you! Louise, Canton Tea Co.

                Wordpress Plugin To Capture Form Completion Data, Before Visitor Hits "Submit"?

                Greetings MOZ Community: Visitors frequently start to enter contact information in the forms on our website, but then chicken out and don't hit the submit button. I noticed this watching the recordings of visitor web site visits using Mouse Flow. Is there a Wordpress Plugin that would allow us to capture data entered in forms, where the visitor does not finally hit the "submit" button? Obviously this would be very, very valuable as this scenario occurs in one out of three or four instances. Thanks!!!

                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
