title: Display certain types of ads in admob?
body: <p>New at using admob within Android.  Is it possible to show ads with certain keywords more frequently?  The opposite of text filters.</p>
  
  <p>Example, my app is targeted for people interested in Japanese culture, language, etc..  Is it possible to display ads that are relevant with the keyword "Japanese".  I noticed I was able to search ads on admob.com using the keyword and a lot of valid ads came up.  I would like my app to display these relevant ads more so than the broad spectrum of ads it displays now.</p>
  
  <p>Thanks in advance!</p>
