For example if I have only one HTML page in my directory and if the link is http://www.mydomain.com/my-landing-page.html and, using .htaccess if I rewrite the URL to http://www.mydomain.com/my-landing-page, should I use canonical tag anywhere?
Or should I apply noindex, nofollow rule in robots.txt file for http://www.mydomain.com/my-landing-page.html?
I want my page look like http://www.mydomain.com/my-landing-page in search engines so, what should I do to http://www.mydomain.com/my-landing-page.html?
