      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?

      User-agent: *

      Disallow: /

        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!

          SEO Best Practices regarding Robots.txt disallow

          I cannot find hard and fast direction about the following issue: It looks like the Robots.txt file on my server has been set up to disallow "account" and "search" pages within my site, so I am receiving warnings from the Google Search console that URLs are being blocked by Robots.txt. (Disallow: /Account/ and Disallow: /?search=). Do you recommend unblocking these URLs? I'm getting a warning that over 18,000 Urls are blocked by robots.txt. ("Sitemap contains urls which are blocked by robots.txt"). Seems that I wouldn't want that many urls blocked. ? Thank you!!

          Should I use noindex or robots to remove pages from the Google index?

          I have a Magento site and just realized we have about 800 review pages indexed. The /review directory is disallowed in robots.txt but the pages are still indexed. From my understanding robots means it will not crawl the pages BUT if the pages are still indexed if they are linked from somewhere else. I can add the noindex tag to the review pages but they wont be crawled. https://www.seroundtable.com/google-do-not-use-noindex-in-robots-txt-20873.html Should I remove the robots.txt and add the noindex? Or just add the noindex to what I already have?

          Moving html site to wordpress and 301 redirect from index.htm to index.php or just www.example.com

          I found page duplicate content when using Moz crawl tool, see below. http://www.example.com
          Page Authority 40
          Linking Root Domains 31
          External Link Count 138
          Internal Link Count 18
          Status Code 200
          1 duplicate http://www.example.com/index.htm
          Page Authority 19
          Linking Root Domains 1
          External Link Count 0
          Internal Link Count 15
          Status Code 200
          1 duplicate I have recently transfered my old html site to wordpress.
          To keep the urls the same I am using a plugin which appends .htm at the end of each page. My old site home page was index.htm. I have created index.htm in wordpress as well but now there is a conflict of duplicate content. I am using latest post as my home page which is index.php Question 1.
          Should I also use redirect 301 im htaccess file to transfer index.htm page authority (19) to www.example.com If yes, do I use
          Redirect 301 /index.htm http://www.example.com/index.php
          or
          Redirect 301 /index.htm http://www.example.com Question 2
          Should I change my "Home" menu link to http://www.example.com instead of http://www.example.com/index.htm that would fix the duplicate content, as indx.htm does not exist anymore. Is there a better option? Thanks

          Dilemma about "images" folder in robots.txt

          Hi, Hope you're doing well. I am sure, you guys must be aware that Google has updated their webmaster technical guidelines saying that users should allow access to their css files and java-scripts file if it's possible. Used to be that Google would render the web pages only text based. Now it claims that it can read the css and java-scripts. According to their own terms, not allowing access to the css files can result in sub-optimal rankings. "Disallowing crawling of Javascript or CSS files in your site’s robots.txt directly harms how well our algorithms render and index your content and can result in suboptimal rankings."http://googlewebmastercentral.blogspot.com/2014/10/updating-our-technical-webmaster.htmlWe have allowed access to our CSS files. and Google bot, is seeing our webapges more like a normal user would do. (tested it in GWT)Anyhow, this is my dilemma. I am sure lot of other users might be facing the same situation. Like any other e commerce companies/websites.. we have lot of images. Used to be that our css files were inside our images folder, so I have allowed access to that. Here's the robots.txt --> http://www.modbargains.com/robots.txtRight now we are blocking images folder, as it is very huge, very heavy, and some of the images are very high res. The reason we are blocking that is because we feel that Google bot might spend almost all of its time trying to crawl that "images" folder only, that it might not have enough time to crawl other important pages. Not to mention, a very heavy server load on Google's and ours. we do have good high quality original pictures. We feel that we are losing potential rankings since we are blocking images. I was thinking to allow ONLY google-image bot, access to it. But I still feel that google might spend lot of time doing that. **I was wondering if Google makes a decision saying, hey let me spend 10 minutes for google image bot, and let me spend 20 minutes for google-mobile bot etc.. or something like that.. , or does it have separate "time spending" allocations for all of it's bot types. I want to unblock the images folder, for now only the google image bot, but at the same time, I fear that it might drastically hamper indexing of our important pages, as I mentioned before, because of having tons & tons of images, and Google spending enough time already just to crawl that folder.**Any advice? recommendations? suggestions? technical guidance? Plan of action? Pretty sure I answered my own question, but I need a confirmation from an Expert, if I am right, saying that allow only Google image access to my images folder. Sincerely,Shaleen Shah

          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?

          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!
