category-treeproduct-urls
I've heard some conflicting opinions on whether having category paths in your product URLS is a good idea. An SEO guide I'm currently using suggests that Magento doesn’t support this functionality very well and it creates duplicate content issues.
In your experience, which is should I have this feature turned on or off?
You must make a Product URL Reindex
Admin Panel -> System -> Index Management -> Catalog URL Rewrites : Reindex data
If you have acces over ssh you can make reindex in terminal
magento_path/shell/ php indexer.php --reindex catalog_url
After make reindex you can empty all cache (just in case)
Admin Panel -> System -> Cache Management -> Flush Magento Cache/ Flush Storage Cache
See Magento build in url rewrites catalog section:

It's fine to have category paths in URL's as long as you also enable canonicals (
system->config->catalog->seo->canonical for categories/products->yes). This will stop any duplicate content issues.
