I have started to add Adsense to my Japanese website: ozfudosan.com. It has very low traffic only coming from a Google Adwords campaign.
I didn’t plan on doing any advertising on the site as I only wanted it to generate leads for my realestate business.
It has only had a couple of clicks but the payouts are very good compared to my other sites, which have higher traffic but advertisers are obviously paying a lot less.
I would like to develop it more, but I cannot write Japanese well enough by myself. I have more ideas to develop the content, but I have to figure in translation costs. If I could just make one house sale I would be happy to invest more in the site and build multiple income streams in the process.
I should also note, that after adding Adsense I was still able generate new leads.
