          Hi,

          I would like to block all URLs with the parameter '?filter=' from being crawled by including them in the robots.txt.

          Which directive should I use:

          User-agent: *
          Disallow: ?filter=

          or

          User-agent: *
          Disallow: /?filter=

          In other words, is the forward slash in the beginning of the disallow directive necessary?

          Thanks!

            Hi Martijn,

            Thanks for the answer. Regarding the forward slash in the beginning, is it necessary to use this?

            In the robots text from Zalando for example, you can see that they don't use it for a lot of filters.

              Uhh, that's not what the requester is looking for and could actually cause tons of problems if you would apply this on a site that you're unaware of. I would always go with the most limiting robots.txt that you can and in this case, I would go with: /?filter=

                Hi,

                The following should suffice as it will black any URL with a "?" in it

                User-agent: *
                Disallow: /*?

                  410 or 301 after URL update?

                  Hi there, A site i'm working on atm has a thousand "not found" errors on google console (of course, I'm sure there are thousands more it's not showing us!). The issue is a lot of them seem to come from a URL change. Damage has been done, the URLs have been changed and I can't stop that... but as you can imagine, i'm keen to fix as many as humanly possible. I don't want to go mad with 301s - but for external links in, this seems like the best solution? On the other hand, Google is reading internal links that simply aren't there anymore. Is it better to hunt down the new page and 301-it anyway? OR should I 410 and grit my teeth while google crawls and recrawls it, warning me that this page really doesn't exist? Essentially I guess I'm asking, how many 301s are too many and will affect our DA? And what's the best solution for dealing with mass 404 errors - many of which aren't attached or linked to from any other pages anymore? Thanks for any insights 🙂

                  Inactive Products - Inactive URLs

                  Hi, In our website www.viatrading.com we have many products that might be in stock or not depending on availability. Until now, when a product was not available anymore, we took this page down (and redirected to its product category page). And, only if the product was available again, we re-activated the URL - this might be days, months or even years later. To make this more SEO-friendly, we decided now that while a product is not available, instead or deactivating/redirecting the page, we will leave it online and just add a message saying "This product is currently not available". If we do this, we will automatically re-activate about 500 products pages at once. 1. Just to make sure, is it harmful for SEO to keep activating/deactivating URLs this way? 2. Since most of these pages have been deindexed for a long time due to being redirected - have they lost all their SEO juice? 3. How can we better activate these old 500 pages - is it ok activating them all at once? Thank you,

                  Recovering from robots.txt error

                  Hello, A client of mine is going through a bit of a crisis. A developer (at their end) added Disallow: / to the robots.txt file. Luckily the SEOMoz crawl ran a couple of days after this happened and alerted me to the error. The robots.txt file was quickly updated but the client has found the vast majority of their rankings have gone. It took a further 5 days for GWMT to file that the robots.txt file had been updated and since then we have "Fetched as Google" and "Submitted URL and linked pages" in GWMT. In GWMT it is still showing that that vast majority of pages are blocked in the "Blocked URLs" section, although the robots.txt file below it is now ok. I guess what I want to ask is: What else is there that we can do to recover these rankings quickly? What time scales can we expect for recovery? More importantly has anyone had any experience with this sort of situation and is full recovery normal? Thanks in advance!

                  Strange URLs, how do I fix this?

                  I've just check Majestic and have seen around 50 links coming from one of my other sites. The links all look like this: http://www.dwww.mysite.com
                  http://www.eee.mysite.com
                  http://www.w.mysite.com The site these links are coming from is a html site. Any ideas whats going on or a way to get rid of these urls? When I visit the strange URLs such as http://www.dwww.mysite.com, it shows the home page of http://www.mysite.com. Is there a way to redirect anything like this back to the home page?

                  Soft 404's from pages blocked by robots.txt -- cause for concern?

                  We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages). Should we be concerned? Is there anything we can do about this?

                  Changing a url from .html to .com

                  Hello, I have a client that has a site with a .html plugin and I have read that its best to not have this. We currently have pages ranking with this .html plug in. However If we take the plug in out will we lose rankings? would we need a 301 or something?

                  Blocking Dynamic URLs with Robots.txt

                  Background: My e-commerce site uses a lot of layered navigation and sorting links.  While this is great for users, it ends up in a lot of URL variations of the same page being crawled by Google.  For example, a standard category page: www.mysite.com/widgets.html ...which uses a "Price" layered navigation sidebar to filter products based on price also produces the following URLs which link to the same page: http://www.mysite.com/widgets.html?price=1%2C250 http://www.mysite.com/widgets.html?price=2%2C250 http://www.mysite.com/widgets.html?price=3%2C250 As there are literally thousands of these URL variations being indexed, so I'd like to use Robots.txt to disallow these variations. Question: Is this a wise thing to do?  Or does Google take into account layered navigation links by default, and I don't need to worry. To implement, I was going to do the following in Robots.txt: User-agent: * Disallow: /*? Disallow: /*= ....which would prevent any dynamic URL with a '?" or '=' from being indexed.  Is there a better way to do this, or is this a good solution? Thank you!

                  URL Length or Exact Breadcrumb Navigation URL? What's More Important

                  Basically my question is as follows, what's better: www.romancingdiamonds.com/gemstone-rings/amethyst-rings/purple-amethyst-ring-14k-white-gold (this would fully match the breadcrumbs). or www.romancingdiamonds.com/amethyst-rings/purple-amethyst-ring-14k-white-gold (cutting out the first level folder to keep the url shorter and the important keywords are closer to the root domain). In this question http://www.seomoz.org/qa/discuss/37982/url-length-vs-url-keywords I was consulted to drop a folder in my url because it may be to long. That's why I'm hesitant to keep the bradcrumb structure the same. To the best of your knowldege do you think it's best to drop a folder in the URL to keep it shorter and sweeter, or to have a longer URL and have it match the breadcrumb structure? Please advise, Shawn
