Do you recommend using SEC page stuffer?

Do you recommend using SEC page stuffer?

I want to boost the keyword quality score of my adword landing pages.

I also need to do this for every keyword.

Any suggestion or tips? Would I need to use page stuffer with the template add-on?

What does basic SEC use for content when using page stuffer?

Is there any way of automating SEC for using sec with many different keyword subdomains?
