For Surihani, I am using FB Adverts to advertise. On first day, I got (30 Likes on fb/sajakiri) within 15 minutes. But I reach my Daily Limit within that 15 minutes time. This is reasonably good result. And we'll see whether we need to increase the allocation, after one month experimenting with this.
Other than that I might use Advertorial Advertising in popular blog such as Oh!Media, BeautifulNara or Murai.com. This is like to pay them to write article/blog, about our product offering.
There is a evolution in our marketing. In yesteryears, we used to rely heavily on gatekeepers for approval; media or labels. But now, thanks to Internet, we can direct our own potential customer, partner or fans.
This is tedious work, but I am sure it's worthwhile.
