Hello,
I made some minor changes to the URL structure of my website about two weeks ago. To be more precise, I use Wordpress and I switched from tags to custom taxonomies. For example:
/tag/stephen-king to /author/stephen-king
/tag/high-fantasy to /genre/high-fantasy
Then I redirected the /tag/ to /genre/ or /author/ accordingly in .htaccess with 301 redirect.
Is it normal that both versions appear in Google index? Let’s say, both /tag/high-fantasy and /genre/high-fantasy appear in search results, even though the first one redirects to the second one. Also Webmaster Tools gives me a lot of “HTML suggestions” regarding duplicate meta descriptions, etc. due to this.
