          I'm about to block off all URLs that have a query string using robots.txt. They're mostly URLs with coremetrics tags and other referrer info. I figured that search engines don't need to see these as they're always better off with the original URL.

          Might there be any downside to this that I need to consider?

          Appreciate your help / experiences on this one.

          Thanks

            Thanks for your suggestions. I've already got canonical tags on every page, but they're not all being adhered to and lots of URLs with query strings are still getting organic traffic.

            Passing referrer info behind scenes isn't an option with Coremetrics I don't think. Is it?

            Interested to know more about number 1 though. How would you do that in WMT other than blocking with robots.txt?

            Thanks

              Instead of blocking them with robots.txt (which isn't very effective), try using the canonical tag instead.

              For instance, a URL like this:
              http://wwww.testdomain.com/page.html?utm_source=Google&utm_medium=Banner&utm_campaign=Campaign

              You could add this canonical tag in the head:

              With this solution you don't have to worry about losing quality links OR having your query tracking show up in any of the major search engines.

              Cheers- Kyle

                The downside to this would be if someone linked to the page with the query string, the search engines wouldn't crawl the page and flow link juice properly to the rest of your site.

                Other options:

                1. Use Google and Bing WMT to ignore those parameter query strings.

                2. Make sure the canoncial tag is on those pages, pointing back to the version without the query string

                3. Try to pass referrer info behind the scenes if possible

                  SEO - New URL structure

                  Hi, Currently we have the following url structure for all pages, regardless of the hierarchy: domain.co.uk/page, such as domain/blog name. Can you, please confirm the following: 1. What is the benefit of organising the pages as a hierarchy, i.e. domain/features/feature-name or domain/industries/industry-name or domain/blog/blog name etc. 2. This will create too many 301s - what is Google's tolerance of redirects? Is it worth for us changing the url structure or would you only recommend to add breadcrumbs? Many thanks Katarina

                  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!

                  URL has caps, but canonical does not. Now what?

                  Hi, Just started working with a site that has the occasional url with a capital, but then the url in the canonical as lower case. Neither, when entered in a browser, resolves to the other. It's a Shopify site. What do you think I should do?

                  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?

                  OK to block /js/ folder using robots.txt?

                  I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1
                  http://www.discoverafrica.com/js/jquery.cookie.js?v=1.1
                  http://www.discoverafrica.com/js/global.js?v=1.2
                  http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
                  http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?

                  Google News URL Format

                  Hi, We are currently redesigning our gaming website (www.totallygn.com) and one of our main goals is to get listed by Google News in future. Looking at the Google News URL requirements "The URL for each article must contain a unique number consisting of at least three digits." How does the above affect SEO structure?  I was planning on using a format such as www.totallygn.com/xbox-360/360-reviews/fifa-12-review how would this compare to something like? www.totallygn.com/xbox-360/360-reviews/fifa-12-review234 Thanks in advance for your help

                  Invisible robots.txt?

                  So here's a weird one... Client comes to me for some simple changes, turns out there are some major issues with the site, one of which is that none of the correct content pages are showing up in Google, just ancillary (outdated) ones. Looks like an issue because even the main homepage isn't showing up with a "site:domain.com" So, I add to Webmaster Tools and, after an hour or so, I get the red bar of doom, "robots.txt is blocking important pages." I check it out in Webmasters and, sure enough, it's a "User agent: * Disallow /" ACK! But wait... there's no robots.txt to be found on the server. I can go to domain.com/robots.txt and see it but nothing via FTP. I upload a new one and, thankfully, that is now showing but I've never seen that before. Question is: can a robots.txt file be stored in a way that can't be seen? Thanks!
