      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!

          XML sitemap generator only crawling 20% of my site

          Hi guys, I am trying to submit the most recent XML sitemap but the sitemap generator tools are only crawling about 20% of my site.  The site carries around 150 pages and only 37 show up on tools like xml-sitemaps.com. My goal is to get all the important URLs we care about into the XML sitemap. How should I go about this? Thanks

          Using a US CDN (Cloudflare) for a UK Site. Should I use a UK Based CDN as it says my server is based in USA

          Hi All, We are a UK Company with Uk customers only and use CloudFlare CND. Our Site is hosted by a UK company with servers here but from looking online and checking where my site is hosted etc etc , some sites are telling me the name of our UK Hosted company and other sites are telling me my site is hosted in San Fran (USA) , where I presume the Cloudflare is based. I know Cloudflare has a couple of servers in the UK it uses but given all my customers are UK based ,I don't want this is affect rankings etc , as I thought it was a ranking benefit to be hosted in the country you are based. Is there any issue with this and should I change or is google clever enough to know so i shouldn't worry. thanks Pet

          How do I add https version of site to Bing webmaster tools?

          I could add my site to Google Webmaster tools with no problems, but when I try to add it in Bing webmaster tools it just redirects me to what I already have. Everything is staying the same but the switch from http to https. Anyone else experienced this? This is what I just received back from Bing and it doesn't seem right- I understand that you switched to the https version of your site and you're now trying to use the Site Move tool. However, in order to do this, you must verify the https version of your site first. You cannot do this because it just redirects you to the dashboard. We thank you for reporting this to us. We've investigated on this matter and can see that you're already put a redirect from the http to the https version of your site. We also checked the /BingSiteAuth.xml file and this also redirects to the https version. At this point, we suggest that you remove the current website (http version) that is verified through Bing Webmaster Tool and add your https domain. When done, use the Site Move tool. Thoughts?

          "noindex, follow" or "robots.txt" for thin content pages

          Does anyone have any testing evidence what is better to use for pages with thin content, yet important pages to keep on a website? I am referring to content shared across multiple websites (such as e-commerce, real estate etc). Imagine a website with 300 high quality pages indexed and 5,000 thin product type pages, which are pages that would not generate relevant search traffic. Question goes: Does the interlinking value achieved by "noindex, follow" outweigh the negative of Google having to crawl all those "noindex" pages? With robots.txt one has Google's crawling focus on just the important pages that are indexed and that may give ranking a boost. Any experiments with insight to this would be great. I do get the story about "make the pages unique", "get customer reviews and comments" etc....but the above question is the important question here.

          Should comments and feeds be disallowed in robots.txt?

          Hi My robots file is currently set up as listed below. From an SEO point of view is it good to disallow feeds, rss and comments? I feel allowing comments would be a good thing because it's new content that may rank in the search engines as the comments left on my blog often refer to questions or companies folks are searching for more information on. And the comments are added regularly. What's your take? I'm also concerned about the /page being blocked. Not sure how that benefits my blog from an SEO point of view as well. Look forward to your feedback. Thanks. Eddy User-agent: Googlebot Crawl-delay: 10 Allow: /* User-agent: * Crawl-delay: 10 Disallow: /wp- Disallow: /feed/ Disallow: /trackback/ Disallow: /rss/ Disallow: /comments/feed/ Disallow: /page/ Disallow: /date/ Disallow: /comments/ # Allow Everything Allow: /*

          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?
