Please help me  to remove duplicate URL in Google's Result. When I type my website in Google Search, I see there are two URL like - 1- www[dot]onlineweb[dot]com/my-blog-post 2- www[dot]onlineweb[dot]com/my-first-blog-post

Actually, I published my post as- www[dot]onlineweb[dot]com/my-blog-post and after few hours I changed it to - www[dot]onlineweb[dot]com/my-first-blog-post . Now I see , Both URL are indexed in Googe.
