      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.

                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!

                What is the best tool to view your page as Googlebot?

                Our site was done with asp.net and a lot of scripting. I want to see what Google can see and what it can't. What is the best tool that duplicates Googlebot? I have found several but they seem old or inaccurate.

                Duplicate H1 tag IF it holds SAME text?

                Hello people, I know that majority of SEO gurus (?) claim that H1 tag should only be used once per page. In the landing page design I'm working with, we actually need to repeat our core message stated in H1 & H2 - at the bottom of the page. Now the question is: Can that in any way cause any ranking penalty from big G? In my eyes that is not attempt to over optimize page as it contains SAME info as the H1 & H2 at the top of the page. Confusing, so I'm hope that some SEO gurus here will share some light on this. Thanks in advance!

                Need to rebuild client's flash website

                I am working with their web designer and need to figure out a way to rebuild their site which is currently all in flash. I was wondering if there was a way to do this without spending a ton of time in completely re-doing the site from scratch.

                The use of foreign characters and capital letters in URL's?

                Hello all, We have 4 language domains for our website, and a number of our Spanish landing pages are written using Spanish characters - most notably: ñ and ó. We have done our research around the web and realised that many of the top competitors for keywords such as Diseño Web (web design) and Aplicaión iPhone (iphone application) DO NOT use these special chacracters in their URL structure. Here is an example of our URL's EX:  http://www.twago.es/expert/Diseño-Web/Diseño-Web However when I simply copy paste a URL that contains a special character it is automatically translated and encoded. EX: http://www.twago.es/expert/Aplicación-iPhone/Aplicación-iPhone (When written out long had it appears: http://www.twago.es/expert/Aplicación-iPhone/Aplicación-iPhone My first question is, seeing how the overwhelming majority of website URL's DO NOT contain special characters (and even for Spanish/German characters these are simply written using the standard English latin alphabet) is there a negative effect on our SEO rankings/efforts because we are using special characters? When we write anchor text for backlinks to these pages we USE the special characteristics in the anchor text (so does most other competitors). Does the anchor text have to exactly I know most webbrowsers can understand the special characters, especially when returning search results to users that either type the special characters within their search query (or not). But we seem to think that if we were doing the right thing, then why does everyone else do it differently? My second question is the same, but focusing on the use of Capital letters in our URL structure. NOTE: When we do a broken link check with some link tools (such as xenu) the URL's that contain the special characters in Spanish are marked as "broken". Is this a related issue? Any help anyone could give us would be greatly appreciated! Thanks, David from twago

                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?
