      I've read an audit where the writer recommended creating and uploading a blank robots.txt file, there was no current file in place.  Is there any merit in having a blank robots.txt file?

      What is the minimum you would include in a basic robots.txt file?

        I know this is four years old, but there's value in having a blank robots.txt as some tools (including the latest version of the Moz crawler) will baulk at sites without a robots.txt file.

          Thanks for both of your replies.  As per my question it was around whether there is any value having a blank robots.txt file.  Philipp's answer was right on the money.

            i mentioned same only, The "User-agent: *" means this section applies to all robots. The "Disallow: /" tells the robot that it should not visit any pages on the site."

            n has added - More and more people use robots,txt to disallow access to some administration or private folders of the site

              No use in having a blank robots.txt. Minimum requirement if you want to have your site crawled is this:

              User-agent: *
              Allow: /
              

              Note that Gagans example above will block the entire site.

                Hi, This is what i got

                " Web site owners use the /robots.txt file to give instructions about their site to web robots; this is called_The Robots Exclusion Protocol_. It works likes this: a robot wants to vists a Web site URL, say http://www.example.com/welcome.html. Before it does so, it firsts checks for http://www.example.com/robots.txt, and finds:

                User-agent: *
                Disallow: /
                
                

                The "<tt>User-agent: *</tt>" means this section applies to all robots. The "<tt>Disallow: /</tt>" tells the robot that it should not visit any pages on the site."

                More and more people use robots,txt to disallow access to some administration or private folders of the site . If you dont want to hide anything then may be you can leave it blank

                  Robots.txt Tester - syntax not understood

                  I've looked in the robots.txt Tester and I can see 3 warnings: There is a 'syntax not understood' warning for each of these. XML Sitemaps:
                  https://www.pkeducation.co.uk/post-sitemap.xml
                  https://www.pkeducation.co.uk/sitemap_index.xml How do I fix or reformat these to remove the warnings? Many thanks in advance.

                  Do I need a separate robots.txt file for my shop subdomain?

                  Hello Mozzers! Apologies if this question has been asked before, but I couldn't find an answer so here goes... Currently I have one robots.txt file hosted at https://www.mysitename.org.uk/robots.txt We host our shop on a separate subdomain https://shop.mysitename.org.uk Do I need a separate robots.txt file for my subdomain? (Some Google searches are telling me yes and some no and I've become awfully confused!

                  Is there a limit to how many URLs you can put in a robots.txt file?

                  We have a site that has way too many urls caused by our crawlable faceted navigation.  We are trying to purge 90% of our urls from the indexes.  We put no index tags on the url combinations that we do no want indexed anymore, but it is taking google way too long to find the no index tags.  Meanwhile we are getting hit with excessive url warnings and have been it by Panda. Would it help speed the process of purging urls if we added the urls to the robots.txt file?  Could this cause any issues for us?  Could it have the opposite effect and block the crawler from finding the urls, but not purge them from the index? The list could be in excess of 100MM urls.

                  Google insists robots.txt is blocking... but it isn't.

                  I recently launched a new website.  During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files.  You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap.  These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are  able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

                  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

                  Converting files from .html to .php or editing .htaccess file

                  Good day all, I have a bunch of files that are .html and I want to add some .php to them. It seems my 2 options are Convert .html to .php and 301 redirect or add this line of code to my .htaccess file and keep all files that are .html as .html AddType application/x-httpd-php .html My gut is that the 2nd way is better so as  not alter any SEO rankings, but wanted to see if anybody had any experience with this line of code in their .htaccess file as definitely don't wan to mess up my entire site 🙂 Thanks for any help! John

                  Is blocking RSS Feeds with robots.txt necessary?

                  Is it necessary to block an rss feed with robots.txt? It seems they are automatically not indexed (http://googlewebmastercentral.blogspot.com/2007/12/taking-feeds-out-of-our-web-search.html) And, google says here that it's important not to block RSS feeds (http://googlewebmastercentral.blogspot.com/2009/10/using-rssatom-feeds-to-discover-new.html) I'm just checking!
