Tag clouds, categories of wordpress make the content of the page indexed twice thrice or even more times.. Practically speaking Google is showing all that content in search result multiple times. My point is: Is this not against panda update made by Google in feb? Why Google is still indexing duplicate pages (with same content) again and again?
this is used linl rel="canonical" Code (markup): , but other pages if are no follow in robots.php also helps , since the google bot will not follow and you will have a unique content and not duplicate
ThemesAddict is right. But i doubt that Google have special algorithm and special rules to handle WP Blogs/Blogs.
but what I found is that the wordpress is not using "canonical" tag in either category or tag clouds. This issue is not only with wordpress even blogger is using "label" without any such tag. I think there must be something which we are ignoring???
