My CTR and eCPM dropped down that month since i changed something on my web site, but I don t know what it was. Is there somewhere you choose the category of the Adsense ads which appear? I mean, how can I include other services than CARS, what I v got for the moment? Second question, can I choose some keywords for ads who appear on my site? Third, is the language determinated from what language is on the page , because my site is in 3 languages? Do you know also companies able to increase these CTR and eCPM? Thank you. Sylvain.
