Welcome to the Q&A Forum

You need to determine first, what is causing duplicate is it Tags - which are causing duplicates Is it like index.php file where site is getting crawled with www.moxicopy.com/blog/index.php is it that a blog is accessed by 2 or more urls like with or without category :- www.moxicopy.com/blog/category/topic and www.maxicopy.com/blog/topic You need to identify the cause, will suggest Noindex to Tags Apply canonical from index.php pages and category pages Point is :- A page should be accessed by 1 url only and all other duplicate should be canonical to original url. This will lead Search Engines to not only index your site better, but even the page authority will also be highest with the main page.

Why would the source code take EVERY single keyword (for over 40 different articles), and link them all together..
