      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

      Jenni

        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

              Same URL for languages sub-directories

              Hi All, I have a main domain and 9 different subdirectories for languages,  example: www.example.com/page.html www.example.com/uk/page-uk.html www.example.com/es/page-es.html we are implementing hreflang tags for the languages, but we are thinking to get rid of the dashes on the languages URL: -uk or -es, so it will be: www.example.com/page.html www.example.com/uk/page.html www.example.com/es/page.hrml would this be a problem? to have same page names even if they are in different subdirectories? would we need to add canonical tags, at lease for the main domain URLs? www.kornferry.com/page.html Thank you, Rachel

              Query string parameters always bad for SEO?

              I've recently put some query string parameters into links leading to a 'request a quote' form which auto-fill the 'product' field with the name of the product that is on the referring product page. E.g. Red Bicycle product page >>> Link to RFQ form contains '?productname=Red-Bicycle' >>>> form's product field's default value becomes 'Red-Bicycle' I know url parameters can lead to keyword cannibalisation and duplicate content, we use sub-domains for our language changer. BUT for something like this, am I potentially damaging our SEO? Appreciate I've not explained this very well. We're using Kentico by the way, so K# macros are a possibility (I use a simple one to fill the form's Default Field).

              Google Search console says 'sitemap is blocked by robots?

              Google Search console is telling me "Sitemap contains URLs which are blocked by robots.txt." I don't understand why my sitemap is being blocked? My robots.txt look like this: User-Agent: *
              Disallow: Sitemap: http://www.website.com/sitemap_index.xml It's a WordPress site, with Yoast SEO installed. Is anyone else having this issue with Google Search console? Does anyone know how I can fix this issue?

              Is there a limit to how many URLs you can put in a robots.txt file?

              We have a site that has way too many urls caused by our crawlable faceted navigation.  We are trying to purge 90% of our urls from the indexes.  We put no index tags on the url combinations that we do no want indexed anymore, but it is taking google way too long to find the no index tags.  Meanwhile we are getting hit with excessive url warnings and have been it by Panda. Would it help speed the process of purging urls if we added the urls to the robots.txt file?  Could this cause any issues for us?  Could it have the opposite effect and block the crawler from finding the urls, but not purge them from the index? The list could be in excess of 100MM urls.

              Blocked URL parameters can still be crawled and indexed by google?

              Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

              Special characters in URL

              Hi There, We're in the process of changing our URL structure to be more SEO friendly. Right now I'm struggling to find a good way to handle slashes that are part of a targeted keyword. For example, if I have a product page and my product title is "1/2 ct Diamond Earrings in 14K Gold" which of the following URLs is the right way to go if I'm targeting the product title as the search keyword? example.com/jewelry/1-2-ct-diamond-earrings-in-14k-gold example.com/jewelry/12-ct-diamond-earrings-in-14k-gold example.com/jewelry/1_2-ct-diamond-earrings-in-14k-gold example.com/jewelry/1%2F2-ct-diamond-earrings-in-14k-gold Thanks!

              Use of + in url good or bad?

              Hi, I am working on a SEO project for a client.
              Some of the urls have a + between the keyword.
              like www.example.com/make+me+happy/ Is this good or bad for seo?
              Or is it maybe better to use - ? Thanks!

              Is blocking RSS Feeds with robots.txt necessary?

              Is it necessary to block an rss feed with robots.txt? It seems they are automatically not indexed (http://googlewebmastercentral.blogspot.com/2007/12/taking-feeds-out-of-our-web-search.html) And, google says here that it's important not to block RSS feeds (http://googlewebmastercentral.blogspot.com/2009/10/using-rssatom-feeds-to-discover-new.html) I'm just checking!
