      I'm in the middle of doing a bunch of 301 redirects for me site. Should I make them Lowercase, uppercase, or does it matter? Also, do I want to be using hyphens (-), or underscores (_)?

      Any other tips?

      EX:

        Are you serving the same page for both /MBA and /mba?  You should set up a 301 redirect from one to the other.

        In Analytics, you can set a custom filter to make your URLs case insensitive, but I don't believe that'll fix the data currently in your account, it'll only fix them going forward.  That process is outlined here: http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=90397.

        My URLs are all lowercased so I can't actually find an example in my account to test, but when I do an advenced filter and select Include Page with the match type of "Matching RegExp" and try URLs with uppercase characters, Analytics appears to be making the query case insensitive.  So you can try that as well.

        If the prior paragraph didn't work for you, you can do this on a URL by URL basis, by doing an advanced search by regular expression and substituting in "[M|m][B|b][A|a]" for "mba".

          John and Team,

          Suppose I have a site with 8000 pages and a small percentage of them in google analytics are showing up twice because the pages are linked through upper and lowercase links.  So in Google analytics (GA) there would be two rows:

          http:///www.blah.com/MBA

          http://www.blah.com/mba

          Is there a type of query I can run in GA to allow me to find all pages where the url is the same except for the upper and lower casing?  I want to go into GA at Standard Reporting -> Content -> all pages and do an advanced search.

            Is the Short Title a redirect or the actual URL? If it's a redirect then it shouldn't be a problem. You can also use canonical if you want to use the lowercase and host the other page. But that's is a sloppy solution.

              I agree with this completely. Lowercase with hyphens is my preference. Some E-commerce  companies (let's use Volusion as an example), give you the choice to use hyphens or underscores in a product's URL. This is nice and they even offer you the ability to write what the URL will be under the "Short TItle" option. However, this "Short Title" option is what will show in your URL AND the link text for a "Related Product" listing on the site. So if I want the link text to look normal when someone sees a Related Product link, I have to capitalize the text I put for the "Short Title" which will then cause the URL to be in Caps as well. This is a pretty significant flaw in their system and I have alerted them to the problem numerous times. Hopefully they will get it fixed soon.

                I agree. Lowercase in the example above. For ease of direct typing.

                But when advertising just a website URL in print offline, caps. www.BulwarkPestControl.com is easier to read than www.bulwarkpestcontrol.com.

                  The fact a Caps create a 404 error on LAMP site is a pet peeve of mine - so is the fact Google thinks mix cases on IIS are separate (thus duplicate) URLs.

                  Too arbitrary to be picky about and cause user frustration.

                  Thanks goodness at lease DoMaInS can be what ever.

                    I like lowercase because when I type URLs by hand, I don't think to capitalize things.  If you capitalize things, you have to get the casing right to make the URL valid (unless you're setting up all sorts of fancy redirects), otherwise you a 404 and are left scratching your head.  Also, I agree with Dan that it looks better.

                    Hyphens vs. underscores is a classic question; Matt Cutts says to go with hyphens: http://www.youtube.com/watch?v=Q3SFVfDIS5k.  I like that better too.

                      I personally prefer lowercase because to me it looks better.  And I prefer hyphens for the same reason, and it seems like these days everyone from WordPress right to the SEOmoz site does it that way.

                        Folders in url structure?

                        Hello, Revamping an out-of-date website and am wondering if I need to include the folders (categories) in the url structure? The proposed structure has 8 main folders. I've been reading that Google is ok if the folder is not included in the url, but is it really? The hesitation I have is that the urls are getting long and the main folder only has only a sub folder beneath it. So, /folder-name/facility-name/treatment-overview. This looks too long, doesn't it? Thanks!

                        Vanity URLs are being indexed in Google

                        We are currently using vanity URLs to track offline marketing, the vanity URL is structured as www.clientdomain.com/publication, this URL then is 302 redirected to the actual URL on the website not a custom landing page. The resulting redirected URL looks like:  www.clientdomain.com/xyzpage?utm_source=print&utm_medium=print&utm_campaign=printcampaign. We have started to notice that some of the vanity URLs are being indexed in Google search. To prevent this from happening should we be using a 301 redirect instead of a 302 and will the Google index ignore the utm parameters in the URL that is being 301 redirect to?  If not, any suggestions on how to handle? Thanks,

                        Category URL Pagination where URLs don't change between pages

                        Hello, I am working on an e-commerce site where there are categories with multiple pages. In order to avoid pagination issues I was thinking of using rel=next and rel=prev and cannonical tags. I noticed a site where the URL doesn't change between pages, so whether you're on page 1,2, or 3 of the same category, the URL doesn't change. Would this be a cleaner way of dealing with pagination?

                        Redirect URLS with 301 twice

                        Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND.  However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS  have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the  "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks

                        Best URL format for pagination

                        We're currently changing the URL format of our website search, we have been discussing a lot and cannot decide the past way to pass the pagination parameter for SEO. We narrowed down to the options. www.website.com/apples/p2 - www.website.com/apples?page=2 - www.website.com/apples/page/2 What would give us best ranking returns? What do you think?

                        Old URL redirect to New URL

                        Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe

                        Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?

                        Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian
