In Google Webmaster Tools I'm dealing with HTML Improvements > Duplicate title tags.
I have a Wordpress site and I use multiple categories for some posts. I have subsequently deleted one category (one week ago).
When I click on the links that Google is telling me are duplicates, both of them actually lead me to the same page.
So for example the two links below come up as duplicates in webmaster tools.
I have deleted the category called 'frontpage' (in hindsight that was a dumb category) so now no matter what link I click in webmaster tools both send me to the url /racing-and-sport/post-tile/
My question is: why is Google seeing these as duplicates still if they are going to the same url? Is it perhaps because I only made this change last week and Google hasn't recrawled my site?
Most of my other duplicates are a result of the 'frontpage' category that has now been deleted. I realise I could have put a nofollow on the 'frontpage' category but it was coming up in all my breadcrumbs instead of the categories I preferred so I got rid of the 'frontpage' category all together.
