Hello! I have this little problem. A few years ago, I had couple of sites, then I closed them. But back then the search engines added those sites of mine into their databases. It's Google and Chinese Baidu. And now their bots query my DNS server for non-existent sites. The complication is this... I've got a working website today. Let's call it site.com And those non-existent sites are like that: forum.site.com (my site's subdomains). The traffic is not significant. But why to have it on a daily basis? As far as I see it, there are two ways to possibly deal with it: a) An administrative way, ie., to contact somehow the search engines and ask them nicely to remove those sites off their db's; b.) A technical way, ie., to deal with it myself with some BIND9 configuration. But I just don't know how to approach the issue, frankly.
Yes. redirect your all old site urls to your new website using 301 redirect. It won't hurt your site SEO and Google will update your url. Hope this will help you.
Hello, I did the same, but one more doubt. I wrote 301Redirection in htaccess yet this is enough or should I need to keep the actual page alive with redirection codes to a new page. Recently I created a Sub-domain for Mobile Version since Jun 2015 and in this month, I created Responsive design and I planned to removed that sub-domain. I just added 301Redirection codes in htaccess and also I wrote 301Redirection codes in all files. For Example, if there is 56php files, then I opened every file and wrote redirection code. Even though I had same in htaccess.
@Zoe Johnson - - I want to remove my entire Sub-domain starts with m.mydomain.com I tried but there is no option like URL removal page as you shown here. Could you just let me know breadcrumb link..
