      Will having 401s on a site negatively impact rankings? (e.g. 401s thrown from a social media sharing icon)

        Hi! We're going through some of the older unanswered questions and seeing if people still have questions or if they've gone ahead and implemented something and have any lessons to share with us. Can you give an update, or mark your question as answered?

        Thanks!

          So how would you block spiders from crawling social media sharing icons? Or is there another workaround?

            Yes, I believe any http error response is a bad thing and could affect your ranking. Even 404's or 301's (when links on-site or in sitemap cause them) are cause for concern. You want to make your site as squeaky clean as possible.

            I regularly use a site crawler to check my site, including sitemap/rss feeds, and fix any non-200 responses.

              First here is an error list: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=40132

              Response code 403 is for requests, where authentication makes no difference, disabled directory browsing.
              401 Unauthorized would be the response to send.

              I'd suggest using robot.txt to stop going to these pages? Or even better, if you can allow Google's spiders access (I'm not 100% sure how this is done)

                How to create site map for large site (ecommerce type) that has 1000's if not 100,000 of pages.

                I know this is kind of a newbie question but I am having an amazing amount of trouble creating a sitemap for our site Bestride.com.  We just did a complete redesign (look and feel, functionality, the works) and now I am trying to create a site map.  Most of the generators I have used "break" after reaching some number of pages.  I am at a loss as to how to create the sitemap.  Any help would be greatly appreciated! Thanks

                Mobile site ranking instead of/as well as desktop site in desktop SERPS

                I have just noticed that the mobile version of my site is sometimes ranking in the desktop serps either instead of as well as the desktop site. It is not something that I have noticed in the past as it doesn't happen with the keywords that I track, which are highly competitive. It is happening for results that include our brand name, e.g '[brand name][search term]'. The mobile site is served with mobile optimised content from another URL. e.g wwww.domain.com/productpage redirects to m.domain.com/productpage for mobile. Sometimes I am only seen the mobile URL in the desktop SERPS, other times I am seeing both the desktop and mobile URL for the same product. My understanding is that the mobile URL should not be ranking at all in desktop SERPS, could we be being penalised for either bad redirects or duplicate content? Any ideas as to how I could further diagnose and solve the problem if you do believe that it could be harming rankings?

                Google ranking my site abroad, how to stop?

                Hi Mozzers, I have a UK based ecommerce site, that sells only to the UK.  Over the last month Google has started ranking my site on foreign flavours of Google, so I keep getting traffic coming to my site from Europe, America and the far east that we could never sell to, and as a result bounce is going up and engagement is going down. They are definitely coming to the site from google searches that relate to my product type, but in regions I do not service. Is there a way to stop google doing this?  I have the target set to UK in WMT, but is there anything else I can do?  I worried about my UK ranking being damaged by an increasing overall bounce rate. Thanks

                What is the best way to find missing alt tags on my site (site wide - not page by page)?

                I am looking to find all the missing alt tags on my site at once. I have a FF extension that use to do it page by page, but my site is huge and that will take forever. Thanks!!

                Subdomain and Domain Rankings

                I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league)  when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks

                Delete old site but redirect domain to a new domain and site

                I just have a quick query and I have a feeling about what the answer is so just wanted to see what you guys thought... Basically I am working on a client site. This client has a few other websites that are divisions of their company. However these divisions/websites are no longer used. They are wanting to delete the websites but redirect the domains to their name main website. They believe this will pass on SEO benefits as these old division sites are old and have a good PR and history. I'm unsure for DEFINITE, which way is correct?

                Google.ca is showing our US site instead of our Canada Site

                When our Canadian users who search on google.ca for our brand (e.g. Travelocity, Travelocity hotels, etc.), the first few results our from our US site (travelocity.com) rather than our Canadian site (travelocity.ca). In Google Webmaster Tools, we've adjusted the geotargeting settings to focus on the appropriate locale, but the wrong country TLD is still coming up at the top via google.ca. What's the best way to ensure our Canadian site comes up instead of the US site on google.ca? Thanks, Tory Smith

                Index forum sites

                Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
