      Hi fellow SEOmozers,

      I noticed that a lot of websites have additional characters and words at the end of the URL in addition keyword optimized URL.  Mostly for E-Commerce sites

      For example: www.yoursite.com/category/keyword?id=12345&Keyword--Category--cm_jdkfls_dklj  or wwww.yoursite.com/category/keyword#83939=-37292

      My question is how does the additional characters or parameters(not necessarily tracking parameters) affect SEO? Does it matter if i have additional keywords in the additional stuff in the URL (1st url example)?

      If you can provide more information, that would be helpful.

      Thank you!

        I've never experienced a noticable, direct effect in this regard, and have experience with ranking pages well with crazy parameters. As long as things are canonicalized properly and the system isn't creating a bunch of duplicate pages with different parameters, you should be fine.

          Hi William,

          Yup, totally understand that what's best for user is best for search engine.  I also agree that having a simple and clean URL www.yoursite.com/category/keyword is definitely better and has more benefits than www.yoursite.com/category/keyword?id=1234%Keyword-_-......

          Let's not compared them to the optimized URL but what do you effect does it have on SEO?  Does it harm the site in general with this type of URL?  Or no effect at all since it also included the keywords in the front and the parameters don't play a role.

            When in doubt, the answer is almost always the same as the answer to, "What is best for the user?"

            Users can't make sense of all those parameters, and bots aren't likely to either. A site like Amazon.com or Canon.com can get away with it, because they have so many other factors going for them. Also, some systems create these parameters automatically, and can't easily be optimized.

            So, to answer your question: It's best not to have those parameters. Users like it without them, and it makes it easier for people to link to you, since URLs are more memorable. On the other side of that, it's not the end of the world if you can't do this in an easy manner and your time might be better spent elsewhere.

              Hi,

              Thanks for the article, it help answer some of my questions. However, the examples in the article compared 2 not optimized URLs with 1 keyword included URL. It makes sense that the 3rd URL will perform better as it includes keyword for search engine, users to understand what the page is about and all the other benefits from optimizing the URL.

              1. Amazon.com - http://www.amazon.com/gp/product/B0007TJ5OG/102-8372974-4064145?v=glance&n=502394&m=ATVPDKIKX0DER&n=3031001&s=photo&v=glance
              2. Canon.com - http://consumer.usa.canon.com/ir/controller?act=ModelDetailAct&fcategoryid=145&modelid=11158
              3. DPReview.com - http://www.dpreview.com/reviews/canonsd400/

              However, in my first example:  www.yoursite.com/category/keyword?id=12345&Keyword--Category--cm_jdkfls_dklj

              The URL included keywords which tell users what the page is about but it also included additional dynamic parameters.

              I'm just wondering if these additional dynamic parameters play any role in SEO.  Harm or benefit?

                  Multiple sub-category of the same name ? does that effect SEO

                  Hello, If I have multiple sub-category of the same name ? does that affect SEO for example I have the following category structure? domain/bmw/series5/2006.html domain/bmw/series5/2007.html .. etc domain/bmw/series3/2007.html domain/bmw/series3/2006.html  ..etc domain/Acura/cl/2006.html domain/Acura/cl/2007.html .. etc I do use canonical url because I may have the same product in multiple categories but my question does google penalize me because I have the same (year) url key for multiple categories  even though I use canonical url ? do I have any advantage in masking them filters vs sub-category from SEO point of view ? specially my goal is to have different meta title and meta description for each sub category ?

                  Old school SEO tools / software / websites

                  Hey Mozzers, I am doing some research and wonder if you can help me out? Before Moz, Hubspot, Majestic, Screaming Frog and all the other awesome SEO tools we use today what were the SEO tools / software / websites that were used for aiding SEO? I guess we can add the recently closed Yahoo! Directory for starters! Thanks!

                  Having 2 domains with same name - Impact on SEO

                  Hi AllAs we still dwindle with the rankings not coming in line with the efforts.I have a question: We have 2 websites 1. http://www.example.com/ (which lost traffic and rank in Jan 2013). So we assumed that it was due to some penguin penalty. So we worked on disavow extra but nothing actually helped.Though there was no manual penalty mentioned in the GWT. Frustrated with this we thought of having another website 6 months back: 2. https://example.org/ - we did all the right things and by the book. But we are not seeing ranking here too. We did backlink analysis on all competitors and worked on only quality links they had. So all our links are highly highly relevant.  But still the ranks are not moving beyond third page...in fact they moved to 6-7 page in last 2-3 days. Please suggest .. 1. is it due to same name of domain (our brand name) causing the issue. If yes should we go for 302 or 301 redirect to save ourselves from any penalty that our last website may have got. We can not leave that name unattended as our cataloges etc have that website mentioned. i will expect a scientific reply here not gut feeling please. 2. Is it to do with .org domain extension that it should not be with commercial organizations like us Kindly reply at the earliest Regards Aman

                  Special Characters in Keywords

                  Do search engines consider keywords such as "1099 E-File Software" & "1099 "EFile Software" the same? Many of the keywords for my website will have a dash "-" when properly spelled out but there are many users who would simply omit it when spelling the word.  Another example would be "W-2 Software" as opposed to "W2 Software".

                  Geo Target Location in your URL Structure

                  Hello everyone at SEOMOZ      😄 I have a question if you would be as kind as to inform me of which direction that I should take on this matter would be the more desirable approach for my seo strategy I have been using my location in my URL structure since I started doing SEO 5 years ago and I have always benefited from including my city in the URL. My question is, since the SEO landscape has change so drastically over the past 2 years and the Search Engines have become much more end user friendly and list suggestions for users as they type would it be more beneficial in 2013 to have the "Keyword" before or after the Geo Targeted Location in the URL structure? I own a computer repair business for the past 6 years now and I know that when i check to see where I am ranking for a particular keyword phrase such as "Computer Repair" GOOGLE detects my location and provides suggestions as I start typing out "Computer Repair" for the search query. One of the suggestions is "Computer Repair Wilmington NC" so I am starting to wonder if placing the Geo Targeted City after the Keyword  would be the wiser choice instead of before it like a couple of years ago? Working Example: Here is a site that I am building out right now to re-brand my business. Currently I have one of the Silo Category Slugs set as seen below using the Location before the Keyword The First Example has the Geo Target Location before the Keyword and looks more natural to visitors on the site (at least to me) however I'm afraid that I may be shooting myself in the foot not placing the keyword before the Target Location? But if I do that, It does not read or flow fluently to the average looker so kinda confused and torn on how to deal with this>! FIRST EXAMPLE: Location Before Keyword Silo Parent Category  = "Computer Repair" http://www.pcmedicsoncall.com/wilmington-nc-computer-repair/ Silo Child Category  =  "Laptop" http://www.pcmedicsoncall.com/wilmington-nc-computer-repair/laptop-repair/ Silo Grand Child Category  =  "LCD Replacement" http://www.pcmedicsoncall.com/wilmington-nc-computer-repair/laptop/lcd-screen-replacement/ **SECOND EXAMPLE: ** Keyword Before Location Silo Parent Category  = "Computer Repair" http://www.pcmedicsoncall.com/computer-repair-wilmington-nc/ Silo Child Category  =  "Laptop" http://www.pcmedicsoncall.com/computer-repair-wilmington-nc/laptop-repair/ Silo Grand Child Category  =  "LCD Replacement" http://www.pcmedicsoncall.com/computer-repair-wilmington-nc/laptop-repair/lcd-screen-replacement/ Which would be the more favorable of the 2 examples that I have given please? Keyword before or After the Geo Targeted Location? thank you

                  Vanity URL's and http codes

                  We have a vanity URL that as recommended is using 301 http code, however it has been discovered the destination URL needs to be updated which creates a problem since most browsers and search engines cache 301 redirects. Is there a good way to figure out when a vanity should be a 301 vs 302/307? If all vanity URL's should use 301, what is the proper way of updating the destination URL? Is it a good rule of thumb that if the vanity URL is only going to be temporary and down the road could have a new destination URL to use 302, and all others 301? Cheers,

                  Does the use of an underscore in filenames adversely affect SEO

                  We have had a page which until recently was ranked first or second by Google UK and also worldwide for the term "Snowbee".  It is now no longer in the top 50. I ran a page optimization report on the url and had a very good score.  The only criticism was that I had used an atypical character in the url.  The only unusual character was an underscore "_"    We use the underscore in most file names without apparent problems with search engines. In fact they are automatically created in html files by our ecommerce software, and other pages do not seem to have been so adversely affected. Should we discontinue this practice?  It will be difficult but I'm sure we can overcome this if this is the reason why Google has marked us down. I attach images of the SEO Report pages 8fDPi.jpg AdLIn.jpg
