I try<% if Linkwww %>
<div class="Linkwww"><a href="http://{$Linkwww}">$Linkwww</a></div>
<% end_if %>but nothing goes

How are you defining your variable?
Test it out with:
<% if Content %>
This page has content!
<% end_if %>That should work.
--
If blocks (http://doc.silverstripe.com/doku.php?id=templates)
<% if Property %>
<% end_if %>If blocks let you mark off optional content in your template. The optional content will only be shown if the requested field / method returns a nonzero value.
