I have two important question before i purchase the pro version
first the zoo component creates duplicates on other languages in multilingual websites .Did sh404sef solve this problem with canonical (automatically)?
i checked the sh404sef before but it just handle similar urls on the same language ! the only reason i want sh404sef is to handle this problem for me .
Second: as i pay for sh404sef how many websites i could install it? i have 4 websites based on zoo and i want to solve this problem for all of them
