      I have been disallowing /*? So I know that works without affecting crawling. I am wondering if I can disallow the faceted nav urls.

      So disallow: /category.html/? /category2.html/? /category3.html/*?

      To prevent the price faceted url from being cached:

      /category.html?price=1%2C1000
      and
      /category.html?price=1%2C1000&product_material=88

      Thanks!

        If you can no-index , follow all but the default, then you will send link juice to the pages but it will return the link juice because it is follow, but they will not index because they are no-index.

        If you use robots, then it can not read the page to follow the links.

          Hey Tyler! haven't seen you on SEOmoz in a while. Hope you are good!

          Check to see if this would make sense for you. GWT > Site Configuration > URL Perameters. It says "Only use this feature if you feel confident about how parameters work for your site. Telling Googlebot to exclude URLs with certain parameters could result in large numbers of your pages disappearing from our index."

            If I can, then I disallow hundreds of pages that are duplicate content and should not be crawled.

            If I don't then I send link juice to urls that I don't want seen.

            This is a good answer though, thanks. Any other thoughts?

              You can, but then you have links passing link juice to non followed pages. it would be better if you used canonical. even better would be to add no-index, follow meta tag when non canonical page is displayed, but this requres some codeing.

                One robots.txt file for multiple sites?

                I have 2 sites hosted with Blue Host and was told to put the robots.txt in the root folder and just use the one robots.txt for both sites. Is this right? It seems wrong. I want to block certain things on one site. Thanks for the help, Rena

                Numbers in URL

                Hey guys! Need your many awesome brains. 🙂 This may be a very basic question but am hoping you can help me out with some insights beyond "because Google says it's better". 🙂 I only recently started working with SEO, and I work for a SaaS website builder company that has millions of open/active user sites, and all our user sites URLs, instead of www.mydomainname.com/gallery or myusername.simplesite.com/about, we use numbers, so www.mysite.com/453112 or myusername.simplesite.com/426521 The Sales manager has asked me to figure out if it will pay off for us in terms of traffic (other benefits?) to change it from the number system to the "proper" and right way of setting up these URLs. He's looking for rather concrete answers, as he usually sits with paid search and is therefore used to the mindset of "if we do x it will yield us y in z months". I'm finding it quite difficult to find case studies/other concrete examples beyond the generic, vague implication that it will simply be "better" (when for example looking at SEO checklists and search engine guidelines). Will it make a difference? How so? I have to convince our developers of the importance and priority of this adjustment, or it will just drown in the many projects they already have. So truly, any insights would be so very welcome. Thank you!

                Will an XML sitemap override a robots.txt

                I have a client that has a robots.txt file that is blocking an entire subdomain, entirely by accident. Their original solution, not realizing the robots.txt error, was to submit an xml sitemap to get their pages indexed. I did not think this tactic would work, as the robots.txt would take precedent over the xmls sitemap. But it worked... I have no explanation as to how or why. Does anyone have an answer to this? or any experience with a website that has had a clear Disallow: / for months , that somehow has pages in the index?

                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

                Robots.txt Sitemap with Relative Path

                Hi Everyone, In robots.txt, can the sitemap be indicated with a relative path? I'm trying to roll out a robots file to ~200 websites, and they all have the same relative path for a sitemap but each is hosted on its own domain. Basically I'm trying to avoid needing to create 200 different robots.txt files just to change the domain. If I do need to do that, though, is there an easier way than just trudging through it?

                Robots.txt file getting a 500 error - is this a problem?

                Hello all! While doing some routine health checks on a few of our client sites, I spotted that a new client of ours - who's website was not designed built by us - is returning a 500 internal server error when I try to look at the robots.txt file. As we don't host / maintain their site, I would have to go through their head office to get this changed, which isn't a problem but I just wanted to check whether this error will actually be having a negative effect on their site / whether there's a benefit to getting this changed? Thanks in advance!

                Should I set up a disallow in the robots.txt for catalog search results?

                When the crawl diagnostics came back for my site its showing around 3,000 pages of duplicate content. Almost all of them are of the catalog search results page. I also did a site search on Google and they have most of the results pages in their index too. I think I should just disallow the bots in the /catalogsearch/ sub folder, but I'm not sure if this will have any negative effect?
