        Dear all, what is the best option? And are the option below good? A: Disallow

        • sort-order (Only URLs with value = asc)

        "A single URL may contain many parameters for each of which you can specify settings. More restrictive settings override less restrictive settings. For example, here are three parameters and their settings"

        source:

        http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1235687

        B:  User-agent:

        Googlebot Disallow: /*.=name$

        for example www.sub.domain.com/collection.html?dir=desc&order=name source: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=156449

        Thanks!

          You could always just use rel="canonical" which would be much better than completely blocking all URL parameters.

            Hey,

            Should that second URL be www.sub.domain.com/collection/adresboeken.html?whatever=something If so, then by using /collection/?* you are saying that anything within /collection/ with a query string should not be indexed. If adresboeken.html always has a query string, it may not get indexed.

            The other options I'd consider before using robots.txt are telling Google to ignore dir=desc&order=color in Google Webmaster Tools parameter handling. This is the best way to handle query string issues. (Assuming you are trying to influence Google. Clearly Google Webmaster Tools won't affect Bing!)

            Another idea is to set a canonical URL on /collection/adresboeken.html referencing /collection/adresboeken.html without the query string. This tells the search engines that the query strings do not make a unique URL. (adresboeken.html?dir=desc&order=color is the same as adresboeken.html?dir=desc&order=price is the same as adresboeken.html?dir=asc&order=color is the same as adresboeken.html, and so on).

            I hope that helps. Thanks,
            Matthew

              Hi,

              Robots.txt works mainly on 2 rules. Those are User-agent: and Disallow:

              User-agent: the name of the robot you need to block

              Disallow: the url or folder or other url with conditions you need to block.

              As you have asked in your question you need to block a url with a condition. But you have to remember that Robot.txt is giving so critical results if you did not use it correctly.

              Anyway in your question, you wanted to block url/pages with query strings like page.html?dir=asc&order=name

              so you have to use following:

              User-agent: *

              Disallow: /*?

              So the above will block all the urls with a question mark (?) for all the search robots. This will not block only page.html?dir=asc&order=name it will alos block comments.html?dir=asc&order=name

              So use it so carefully.

              Hope this is the what you have looked for. If need more help you may ask.

              Regards

              Prasad

                Dear all,

                thanks for responding. If I have a pages like

                1. www.sub.domain.com/collection.html exists, I want to index it, and

                2. www.sub.domain.com/collection.html?dir=desc&order=color which I don't want to index

                Is this the way to do this in de robots.txt?:

                Disallow: /collection/?*

                Thanks!

                  Hi,

                  Here is an article explaining how to do this in robots.txt:
                  http://sanzon.wordpress.com/2008/04/29/advanced-usage-of-robotstxt-w-querystrings/

                  Depending on what you are trying to do, it might also be worth investigating parameter handling in Google Webmaster Tools:
                  http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1235687

                  Thanks,

                    Sudden Indexation of "Index of /wp-content/uploads/"

                    Hi all, I have suddenly noticed a massive jump in indexed pages. After performing a "site:" search, it was revealed that the sudden jump was due to the indexation of many pages beginning with the serp title "Index of /wp-content/uploads/" for many uploaded pieces of content & plugins. This has appeared approximately one month after switching to https. I have also noticed a decline in Bing rankings. Does anyone know what is causing/how to fix this? To be clear, these pages are **not **normal /wp-content/uploads/ but rather "index of" pages, being included in Google. Thank you.

                    Robots.txt & meta noindex--site still shows up on Google Search

                    I have set up my robots.txt like this: User-agent: *
                    Disallow: / and I have this meta tag in my on a Wordpress site, set up with SEO Yoast name="robots" content="noindex,follow"/> I did "Fetch as Google" on my Google Search Console My website is still showing up in the search results and it says this: "A description for this result is not available because of this site's robots.txt" This site has not shown up for years and now it is ranking above my site that I want to rank for this keyword. How do I get Google to ignore this site? This seems really weird and I'm confused how a site with little content, that has not been updated for years can rank higher than a site that is constantly updated and improved.

                    Robots txt. in page with 301 redirect

                    We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? Thanks

                    Query Strings causing Duplicate Content

                    I am working with a client that  has multiple locations across the nation, and they recently merged all of the location sites into one site. To allow the lead capture forms to pre-populate the locations, they are using the query string  /?location=cityname on every page. EXAMPLE - www.example.com/product www.example.com/product/?location=nashville www.example.com/product/?location=chicago There are thirty locations across the nation, so, every page x 30 is being flagged as duplicate content... at least in the crawl through MOZ. Does using that query string actually cause a duplicate content problem?

                    No Index PDFs

                    Our products have about 4 PDFs a piece, which really inflates our indexed pages. I was wondering if I could add REL=No Index to the PDF's URL? All of the files are on a file server, so they are embedded with links on our product pages. I know I could add a No Follow attribute, but I was wondering if any one knew if the No Index would work the same or if that is even possible. Thanks!

                    Robots.txt on http vs. https

                    We recently changed our domain from http to https. When a user enters any URL on http, there is an global 301 redirect to the same page on https. I cannot find instructions about what to do with robots.txt. Now that https is the canonical version, should I block the http-Version with robots.txt? Strangely, I cannot find a single ressource about this...

                    Internal search : rel=canonical vs noindex vs robots.txt

                    Hi everyone, I have a website with a lot of internal search results pages indexed. I'm not asking if they should be indexed or not, I  know they should not according to Google's guidelines. And they make a bunch of duplicated pages so I want to solve this problem. The thing is, if I noindex them, the site is gonna lose a non-negligible chunk of traffic : nearly 13% according to google analytics !!! I thought of blocking them in robots.txt. This solution would not keep them out of the index. But the pages appearing in GG SERPS would then look empty (no title, no description), thus their CTR would plummet and I would lose a bit of traffic too... The last idea I had was to use a rel=canonical tag pointing to the original search page (that is empty, without results), but it would probably have the same effect as noindexing them, wouldn't it ? (never tried so I'm not sure of this) Of course I did some research on the subject, but each of my finding recommanded one of the 3 methods only ! One even recommanded noindex+robots.txt block which is stupid because the noindex would then be useless... Is there somebody who can tell me which option is the best to keep this traffic ? Thanks a million

                    Why is a 301 redirected url still getting indexed?

                    We recently fixed a redirect issue in a website, and although it appears that the redirection is working fine, the url in question keeps on getting crawled, indexed and cached by google. The redirect was done a month ago, and google shows cached version of it, even for a couple of days ago. Manual checking shows that its being redirected, and also a couple of online tools i checked report a 301 redirect. Do you have any idea why this could be happening? The website I'm talking about is www.hotelmajestic.gr and its being redirected to www.hotel-majestic.gr
