Is there a best practice/convention to have www.example.com as opposed to www.example.com/index.php in a site's URL? I made the links to the homepage relative (i.e. href="index.php") as opposed to absolute, which causes "index.php" to appear in the URL.
Does this impact SEO, or is it considered sloppy? Should I write an apache rewrite rule to change requests to www.example.com/index.php to www.example.com?
