chunsangh, be aware that you are mixing various dimension/metric scopes:
- Keyword is of session scope (and same applies to conversion).
- Page Title is of page scope.
Building a custom report with Page Title as Dimension and Goal Completitions as Metric wouldn't make sense as there is no way how you can make a direct link between those two. Read this brilliant article by Avinash. Try using metric Page Value metric instead.
To answer the other part of your quesion: goal is accomplished when the required conditions are met. You can review all the goals in Admin section.
Hope this helps!
