All pages are included twice. The only difference is network protocols, one is "http", and the other is "https". Why? How to deal with this problem? I need you help! Thank you!
This is because you apparently have https (SSL) activated for your website. If you are not using SSL you could 301 redirect all https pages to their http equivalent by adding this code in your htaccess file: RewriteCond %{HTTPS} =on [OR] RewriteCond %{SERVER_PORT} ^443$ RewriteRule ^(.*)$ http://www.yourwebsiteaddress.com/$1 [R=301,L] After a while google would remove the https pages from the index
