title: How to remove duplicate title and meta description tags if google indexed them
body: <p>So, I have been building an ecommerce site for a small company. </p>
  
  <p>The url structure is : www.example.com/product_category/product_name and the site has around 1000 products. </p>
  
  <p>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:</p>
  
  <p>-www.example.com/product_category/product_name</p>
  
  <p>and</p>
  
  <p>-www.example.com/product_category/product_name/ (with slash in the end)</p>
  
  <p>got indexed as separate pages.</p>
  
  <p>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. </p>
  
  <p>I did not get any manual action message.</p>
  
  <p>So I have two questions: </p>
  
  <p>-<strong>how can I accelerate the reindexation process, if it's possible?</strong></p>
  
  <p>-and <strong>do these tags hurt my organic search results?</strong> I've googled it, yes and some say it does and some say it doesn't. </p>
