      Hello,

      This is the first time I've asked a question here, but I would really appreciate the advice of the community - thank you, thank you!  Scenario:  Internal linking is pointing to two different versions of a URL, one with brackets [] and the other version with the brackets encoded as %5B%5D

      Version 1: http://www.site.com/test?hello**[]=all&howdy[]=all&ciao[]=all
      Version 2: http://www.site.com/test?hello
      %5B%5D**=all&howdy**%5B%5D**=all&ciao**%5B%5D**=all

      Question: Will search engines view these as duplicate content?  Technically there is a difference in characters, but it's only because one version encodes the brackets, and the other does not (See: http://www.w3schools.com/tags/ref_urlencode.asp)

      We are asking the developer to encode ALL URLs because this seems cleaner but they are telling us that Google will see zero difference.   We aren't sure if this is true, since engines can get so _hung up on even one single difference in character.  _

      We don't want to unnecessarily fracture the internal link structure of the site, so again - any feedback is welcome, thank you. 🙂

        Thanks guys - yes, we're using canonical tags already to help resolve this, but I'd like even better if we didn't have to resort to this. It also makes me nervous that these characters are technically classified as "unsafe", but I haven't been able to find any official word from Google on whether or not they will index URLs with brackets or not.  It's definitely not the web standard....

          Hi,

          I wouldn't worry to much on this issue, it's true that you don't want to depend on the level of the Googlebot to find out if this could be an issue but I think that the encoding of characters will make sure you'll be fine. As a suggestion I would say use canonical tags on of these pages to direct Google or other search engines to the right page. This makes sure you'll never get an issue with duplicate content. However I really doubt that this will turn into an issue.

            Hi Mirabile,

            This is a difficult one. My understanding would be to use the hexadecimal encoding of potentially unsafe characters (of which a square bracket would be) in a URL (i.e. %5b instead of [ ), but I think assuming the URLs are the same, then it makes no difference.

            But that said, whilst Google might read the URLs as the same, that's not to say another search engine will do that as well. And then, what about how a browser might interpret a URL encoded differently but being effectively the same?

            Probably, the main danger is that the search engine or the browser won't be able to follow the link with unsafe characters in at all.

            I'm not sure that is the full answer you were looking for, but maybe someone with more expertise will be able to shed more light on this for you.

            I hope my answer helps at least in part.

            Peter

              Will I be flagged for duplicate content by Google?

              Hi Moz community, Had a question regarding duplicate content that I can't seem to find the answer to on Google. My agency is working on a large number of franchisee websites (over 40) for one client, a print franchise, that wants a refresh of new copy and SEO. Each print shop has their own 'microsite', though all services and products are the same, the only difference being the location. Each microsite has its own unique domain. To avoid writing the same content over and over in 40+ variations, would all the websites be flagged by Google for duplicate content if we were to use the same base copy, with the only changes being to the store locations (i.e. where we mention Toronto print shop on one site may change to Kelowna print shop on another)? Since the print franchise owns all the domains, I'm wondering if that would be a problem since the sites aren't really competing with one another. Any input would be greatly appreciated. Thanks again!

              Forwarded vanity domains, suddenly resolving to 404 with appended URL's ending in random 5 characters

              We have several vanity domains that forward to various pages on our primary domain.
              e.g. www.vanity.com (301)--> www.mydomain.com/sub-page (200) These forwards have been in place for months or even years and have worked fine.  As of yesterday, we have seen the following problem.  We have made no changes in the forwarding settings. Now, inconsistently, they sometimes resolve and sometimes they do not.  When we load the vanity URL with Chrome Dev Tools (Network Pane) open, it shows the following redirect chains, where xxxxx represents a random 5 character string of lower and upper case letters.  (e.g. VGuTD) EXAMPLE:
              www.vanity.com                                  (302, Found) -->
              www.vanity.com/xxxxx                        (302, Found) -->
              www.vanity.com/xxxxx                        (302, Found) -->
              www.vanity.com/xxxxx/xxxxx               (302, Found) -->
              www.mydomain.com/sub-page/xxxxx (404, Not Found) This is just one example, the amount of redirects, vary wildly.  Sometimes there is only 1 redirect, sometimes there are as many as 5. Sometimes the request will ultimately resolve on the correct mydomain.com/sub-page, but usually it does not (as in the example above). We have cross-checked across every browser, device, private/non-private, cookies cleared, on and off of our network etc...   This leads us to believe that it is not at the device or host level. Our Registrar is Godaddy.  They have not encountered this issue before, and have no idea what this 5 character string is from.  I tend to believe them because per our analytics, we have determined that this problem only started yesterday. Our primary question is, has anybody else encountered this problem either in the last couple days, or at any time in the past?  We have come up with a solution that works to alleviate the problem, but to implement it across hundreds of vanity domains will take us an inordinate amount of time.  Really hoping to fix the cause of the problem instead of just treating the symptom.

              Why is /home used in this company's home URL?

              Just working with a company that has chosen a home URL with /home latched on - very strange indeed - has anybody else comes across this kind of homepage URL "decision" in the past? I can't see why on earth anybody would do this! Perhaps simply a logic-defying decision?

              Does DMCA protection actually improve search rankings (assuming no one's stolen my content)

              Hello Moz Community, I had a conversation with someone who claimed that implementing a DMCA protection badge, such as those offered at http://www.dmca.com/ for $10/mo, will improve a site's Google rankings.  Is this true? I know that if my content is stolen it can hurt my rankings (or the stolen content can replace mine), but I'm asking if merely implementing the badge will help my rankings. Thanks! Bill

              Using the same content on different TLD's

              HI Everyone, We have clients for whom we are going to work with in different countries but sometimes with the same  language. For example we might have a client in a competitive niche working in Germany, Austria and Switzerland (Swiss German) ie we're going to potentially rewrite our website three times in German, We're thinking of using Google's href lang tags and use pretty much the same content - is this a safe option, has anyone actually tries this successfully or otherwise? All answers appreciated. Cheers, Mel.

              After reading of Google's so called "over-optimization" penalty, is there a penalty for changing title tags too frequently?

              In other words, does title tag change frequency hurt SEO ? After changing my title tags, I have noticed a steep decline in impressions, but an increase in CTR and rankings. I'd like to once again change the title tags to try and regain impressions. Is there any penalty for changing title tags too often? From SEO forums online, there seems to be a bit of confusion on this subject...

              How Google treat internal links with rel="nofollow"?

              Today, I was reading about NoFollow on Wikipedia. Following statement is over my head and not able to understand with proper manner. "Google states that their engine takes "nofollow" literally and does not "follow" the link at all. However, experiments conducted by SEOs show conflicting results. These studies reveal that Google does follow the link, but does not index the linked-to page, unless it was in Google's index already for other reasons (such as other, non-nofollow links that point to the page)." It's all about indexing and ranking for specific keywords for hyperlink text during external links. I aware about that section. It may not generate in relevant result during any keyword on Google web search. But, what about internal links? I have defined rel="nofollow" attribute on too many internal links. I have archive blog post of Randfish with same subject. I read following question over there. Q. Does Google recommend the use of nofollow internally as a positive method for controlling the flow of internal link love? [In 2007] A: Yes – webmasters can feel free to use nofollow internally to help tell Googlebot which pages they want to receive link juice from other pages
              _
              (Matt's precise words were: The nofollow attribute is just a mechanism that gives webmasters the ability to modify PageRank flow at link-level granularity. Plenty of other mechanisms would also work (e.g. a link through a page that is robot.txt'ed out), but nofollow on individual links is simpler for some folks to use. There's no stigma to using nofollow, even on your own internal links; for Google, nofollow'ed links are dropped out of our link graph; we don't even use such links for discovery. By the way, the nofollow meta tag does that same thing, but at a page level.) Matt has given excellent answer on following question. [In 2011] Q: Should internal links use rel="nofollow"?  A:Matt said: "I don't know how to make it more concrete than that." I use nofollow for each internal link that points to an internal page that has the meta name="robots" content="noindex" tag. Why should I waste Googlebot's ressources and those of my server if in the end the target must not be indexed? As far as I can say and since years, this does not cause any problems at all. For internal page anchors (links with the hash mark in front like "#top", the answer is "no", of course. I am still using nofollow attributes on my website. So, what is current trend? Will it require to use nofollow attribute for internal pages?
