How do I filter my google ads

Hey Folks..


Longtime since I posted here.

The advts displayed in my site are really wague. Say for eg, I am having a job forum which uses a common word called "Passout". Now Google uses tis word and displays many ads for word "Password"

Is there any way I can put keywords so that the advts displayed are relevant to the body or content of the site
