I have a prestashop 1.6. Due a I had dirty urls with ids, last week I bought a module to clean those urls, http://addons.prestashop.com/es/16633-pretty-urls.html.
A couple of days ago, I noticed a dropp of positions in Google. I have checked Google Search console and I can see that all my products and categories are marked as duplicated, (old url with ID and new one)
After that, I have cheked the old urls have a 301 redirection, first visually and also using tools like http://www.seoreviewtools.com/redirect-checker-tool/ It seems all 301 redirections are ok
But now, I don´t know what to do...Any help or idea??
Thanks a lot!
