So basically , Google is treating www.example/cz and example.cz/index.php as two duplicates when they have the same meta descriptions ... So example.com/cz and example.com/cz/index should not have the same meta description.
How can I assign different meta descriptions to example.com/cz and example.com/cz/index.php , I tried to use $_SERVER['self'] in PHP , but it still returns index.php ... How should I tackle this.
