Welcome to the Q&A Forum

hi, I do have an ecommerce website (www.soundcreation.ro) which in the last 3 months had a drop in the SERP. Started to look around in GWT what is happening. Google is reporting a lot of duplicate meta-tags (and meta-titles problem). But 99% of them had already canonical links setted. I tried to optimize my product listings with the new "prev", "next" tags and introduced also the "view-all" canonical link to help Google identify the appropiate product listing pages. SeoMoz is not reporting thos duplicate meta issues. Here is an example of the same page with different links, but with the same common canonical and reported by GWT "duplicate title tag": http://www.soundcreation.ro/chitare-chitari-electroacustice-cid10-pageall/http://www.soundcreation.ro/chitare-chitari-electroacustice-cid10/http://www.soundcreation.ro/chitare-chitari-electroacustice-cid10_999/http://www.soundcreation.ro/chitare-electro-acustice-cid10_1510/What could be the issue?- only that gwt is not refreshing as should be, keeping old errors?- if so, then there is an other serious issue because of why our PR is dropping on several pages?- do we have other problem with the site, which ends up with google penalizing us? Thank you for your ideas!
