So, I have been building an ecommerce site for a small company.
The url structure is : www.example.com/product_category/product_name and the site has around 1000 products.
I've checked google webmaster tools and in the HTML improvements section it shows that I have multiple title and meta description tags for all the product pages. They all appear two times, both:
-www.example.com/product_category/product_name
and
-www.example.com/product_category/product_name/ (with slash in the end)
got indexed as separate pages.
I've added a 301 redirect from every www.example.com/product_category/product_name/ to www.example.com/product_category/product_name, but this was almost two weeks ago. I have resubmitted my sitemap and asked google to fetch the whole page a few times. Nothing has changed, GWT still shows the pages as duplicate tags.
I did not get any manual action message.
So I have two questions:
-how can I accelerate the reindexation process, if it's possible?
-and do these tags hurt my organic search results? I've googled it, yes and some say it does and some say it doesn't.
An option is to set a canonical link on both URLs (with and without /) using the URL without a /. Little by little, Google will stop complaining. Keep in mind Google Webmaster Tools is slow to react, especially when you don't have much traffic or backlinks.
And yes, duplicate tags can influence your rankings negatively because users won't have proper and specific information for each page.
