I have changed taxonomy of the "ad listing" and the "ad-category" translating the words in italian. Google web master tools show as an error "doble title tags" and it shows there are two urls: one with the original taxonomy and one with the translated one (see pictures). How to solve this problem?
Could this affect the seo?
Another problem...I have read in the forum regarding the seo plugin and I have just changed seo plugin from all in seo pack to yoast seo plugin. Two days after I disappeared from the google serp... I have configured the plugin like adviced in a lot of discussion in the forum... Anyone can advice???
