To avoid duplicate content problem with search engines, you have to redirect all pages to one common URL.

This you can achieve using mod_rewrite of apache and .htaccess.

To redirect any URL starting with www.domain.tld to domain.tld, you have to add the following code to .htaccess file.

Do a 301 redirect for all http requests that are going to the wrong url.

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.domain\.tld$ [NC]
RewriteRule ^(.*)$ http://domain.tld/$1 [R=301,L]
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^domain.tld$ [NC]
RewriteRule ^(.*)$ http://domain.tld/$1 [L,R=301]
</IfModule>

To redirect domain.tld to www.domain.tld -

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^domain\.tld$ [NC]
RewriteRule ^(.*)$ http://www.domain.tld/$1 [R=301,L]
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www.domain.tld$ [NC]
RewriteRule ^(.*)$ http://www.domain.tld/$1 [L,R=301]
</IfModule>
