Canonical alias (SUMA)

Blanks doubled content to avoid it and then shows the preferred version of the URL during indexing.

Goolge placed a new Metatag for the search engines: <link rel=“canonical”, which avoids double content and shows a preferred version of an indexed URL. In large sitemap.php the webmaster tools often shows dozens of doubly indicated pages. Often pages are indexed with the category ID, then with a category alias or with index.php? + article ID´s at the same time. The contents is always the same.
