      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.

                Making html table as 'seofriendly' as possible

                Hi, On my website I have a table with a list of products, on every row I have a different product and a different property on each column. The table is made with css so the html code is clean. The problem is (I guess) that google doesn't 'understand' what its inside on the table. So if I do a google search that page appears on the page 87, there is any way to improve my SEO without changing the table? Or to improve my SEO I must change the format of my content? In resume, I want to improve the SEO page of a page that contains information organized inside a table. I don't know if there is a specific answer to this question. Any help is welcome. Regards

                Https pages indexed but all web pages are http - please can you offer some help?

                Dear Moz Community, Please could you see what you think and offer some definite steps or advice.. I contacted the host provider and his initial thought was that WordPress was causing the https problem ?: eg when an https version of a page is called, things like videos and media don't always show up. A SSL certificate that is attached to a website, can allow pages to load over https. The host said that there is no active configured SSL it's just waiting as part of the hosting package just in case, but I found that the SSL certificate is still showing up during a crawl.It's important to eliminate the https problem before external backlinks link to any of the unwanted https pages that are currently indexed. Luckily I haven't started any intense backlinking work yet, and any links I have posted in search land have all been http version.I checked a few more url's to see if it’s necessary to create a permanent redirect from https to http. For example, I tried requesting domain.co.uk using the https:// and the https:// page loaded instead of redirecting automatically to http prefix version.  I know that if I am automatically redirected to the http:// version of the page, then that is the way it should be. Search engines and visitors will stay on the http version of the site and not get lost anywhere in https. This also helps to eliminate duplicate content and to preserve link juice. What are your thoughts regarding that?As I understand it, most server configurations should redirect by default when https isn’t configured, and from my experience I’ve seen cases where pages requested via https return the default server page, a 404 error, or duplicate content. So I'm confused as to where to take this.One suggestion would be to disable all https since there is no need to have any traces to SSL when the site is even crawled ?. I don't want to enable https in the htaccess only to then create a https to http rewrite rule; https shouldn't even be a crawlable function of the site at all.RewriteEngine OnRewriteCond %{HTTPS} offor to disable the SSL completely for now until it becomes a necessity for the website.I would really welcome your thoughts as I'm really stuck as to what to do for the best, short term and long term.Kind Regards

                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.

                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

                Wordpress: Pages vs Posts vs Portfolio

                Hi All, I'm looking to put pen to paper and design my main structual template for my website. I will be creating the new site in Wordpress. My understanding of Wordpress is broken into the Static Pages, Posts and Portfolio. Static PAGE
                Static one off content.
                No tags, categories or archived Posts
                content entries, which is listed in reverse chronological order.
                Update post entry to maintain overall freshness of your website.
                tags, categories & archived Portfolio
                ????? Question What are the benefits of a portfolio page over Static Pages & Posts When creating feature rich articles should i use static pages, posts or portfolio. Thanks Mark

                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

                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 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.
