i have been trying to figure out a problem i am seeing in google analytics with a few internationalized sites that have chinese translations.
if i look at Traffic Sources by Keywords or Search Engines for these sites, i will see some english and chinese keywords along with several keywords that look like junk.
the "garbage keyword" traffic may come from google, yahoo or baidu search engines and in an overwhelming majority of cases the search originated in china.
it's obviously not specific to the translated sites because these are search terms, so it is data coming from the search engines' search forms and thus references from the SERPs.
it's also not a browser issue on my end since i can see some of the chinese search terms.
i haven't noticed any equivalent issues on these sites when looking through top search queries in GWT.
any thoughts or experiences to share?
