Im tempted to use this stratergy. Thank you in advance.

Hi you can use spyfu tool for competitor analysis. It is the best tool tool for competitor.

To enable or disable pingbacks and trackbacks, follow these steps:
Log in to WordPress as the administrator.
In the left pane of the dashboard, click Settings, and then click Discussion.
In the Default article settings section: ...
Click Save Changes.
