      my site uses is set up at http://www.site.com I have my site redirected from non- www to the www in htacess file. My question is... what should my robots.txt file look like for the non-www site? Do you block robots from crawling the site like this? Or do you leave it blank?

        Hi there

        If you configured this properly, I wouldn't worry about this at all.

        Check your internal links and sitemap to make sure that your URLs listed as a reflection of this www. version.

        Beyond that, you're all good, no need to block non www.

        Hope this helps! Good luck!

          Large robots.txt file

          We're looking at potentially creating a robots.txt with 1450 lines in it. This will remove 100k+ pages from the crawl that are all old pages (I know, the ideal would be to delete/noindex but not viable unfortunately) Now the issue i'm thinking is that a large robots.txt will either stop the robots.txt from being followed or will slow our crawl rate down. Does anybody have any experience with a robots.txt of that size?

          ScreamingFrog won't crawl my site.

          Hey guys, My site is Netspiren.dk and when I use a tool like Screaming Frog or Integrity, it only crawls my homepage and menu's - not product-pages. Examples
          A menu: http://www.netspiren.dk/pl/Helse-Kosttilskud-Blandingsolie_57699.aspx
          A product: http://www.netspiren.dk/pi/All-Omega-3-6-9-180-kapsler_1412956_57699.aspx Is it because the products are being loaded in Javascript? 
          What's your recommendation? All best,
          Fred.

          Switching site from non-www to www

          Howdy folks, I've got a website that is roughly 3 months old. I created it as a naked URL as I often prefer the look but I've noticed that a lot of my competition has www and also some of my clients seem to prefer it as well. I feel like switching it to www will be of long-term benefit for my site. The problem is that I currently have several pages with first page rankings and a backlinks. I am wondering what the negative effects of switching it to www would be, and how I can minimize any issues. I am guessing I should do a redirect, and I have access to some of the backlinks so I can change those as well, but is there anything else? Thoughts? I appreciate the feedback!

          Moving to a new site while keeping old site live

          For reasons I won't get into here, I need to move most of my site to a new domain (DOMAIN B) while keeping every single current detail on the old domain (DOMAIN A) as it is. Meaning, there will be 2 live websites that have mostly the same content, but I want the content to appear to search engines as though it now belongs to DOMAIN B. Weird situation. I know. I've run around in circles trying to figure out the best course of action. What do you think is the best way of going about this? Do I simply point DOMAIN A's canonical tags to the copied content on DOMAIN B and call it good? Should I ask sites that link to DOMAIN A to change their links to DOMAIN B, or start fresh and cut my losses? Should I still file a change of address with GWT, even though I'm not going to 301 redirect anything?

          Using both dofollow & nofollow links within the same blog site (but different post).

          Hi all, I have been actively pursuing bloggers for my site in order to build page rank. My website sells women undergarments that are more on the exotic end. I noticed a large amount of prospective bloggers demand product samples. As already confirm, bloggers that are given "free" samples should use a rel=no follow attribute in their links. Unfortunately this does not build my page rank or transfer links juice. My question is this: is it advisable for them to also blog additional posts and include dofollow links? The idea is for the blogger to use a nofollow when posting about the sample and a regular link for a secondary post at a later time. What are you thoughts concerning this matter?

          Redirecting non www site

          Hello Ladies and Gentlemen. I 100% agree with the redirecting of the non www domain name. After all we see so many times, especially in MOZ how the two different domains contain different links, different DA and of course different PA. So I have posed the question to our IT company, "How would we go about redirecting our non www domain to the www version?", "Where would we do that?", " we cant do the redirect on our webserver because the website is listed as an IP address, not a domain name, so would we do the redirect somewhere at GoDaddy?" who is currently maintain our DNS record So here is the response from IT:  " I would setup a CNAME record in DNS (GoDaddy), such that no matter if you go to the bare domain, or the www, you end up in the same place. As for SEO, having a 301 redirect for your bare domain isn't necessary, because both the bare domain and the www are the same domain.  301 is a redirect for "permanently moved" and is common when you change domain names.  Using the bare domain or the www are NOT DIFFERENT DOMAINS, so the 301 would not be accurate, and you'd be telling engines you've moved, when you haven't - which may negatively impact your rank. It sounds to me that IT is NOT recommending the redirect. How can this be? Or are we talking about two different things? Will the redirect cause the melt down as the IT company suggests? Or do they nut understand SEO?

          Block an entire subdomain with robots.txt?

          Is it possible to block an entire subdomain with robots.txt? I write for a blog that has their root domain as well as a subdomain pointing to the exact same IP. Getting rid of the option is not an option so I'd like to explore other options to avoid duplicate content. Any ideas?
