I am having a website which is 3 years old, now I wanted to do some SEO chages into it. so, changed the some urls. From: /psd-layouts.html to /psd-web-layouts.htmlNow my question is that, I had redirect request from first one to second one, but still when checked in Google Webmaster Tools (HTML Improvements section) it shows me that duplicates of the title and meta.So what should I do for overcome of this situation. I thought that I have to put canonical tag or put first URL in robots.txt but still I am confused for this..If i would go for canonical tag then How can I put it out: please input your expert thoughts here
