In comparison with Google Adwords, Yahoo Japan PPC has benefits below.
Show current rank for keywords
Adwords only shows you the average ranking position for keywords, however, Yahoo Japan PPC displays not only the average position but also current rank. It is very helpful for you to avoid “blind” bidding.
Can show you how much you should bid for your chosen position
Again, exact match type only makes Search Ads able to see exactly how many bidders are competing for the same keyword, and can easily work out how much bid you should set for a specific position.
