Hello there.... in my photography blog I just changed my permalink in WP to a more structured solution that better cover and describe the variety of pictures and images displayed.
So i moved from...
I use Platinum SEO pack plugin in WP and I have everything re-directly 301 smoothly to the new url.
If I digit the old url in the browser I got the new one and the correct page.
Also the canonical link is created correctly and is the new one.
All look perfect but... Google webmaster tool is finding out hundreds of duplicate content considering wrongly the old url and the new url as different pages (and so obviously same title and description).
What I should do?
