XF 1.2 SEO after installing new installation

What improvements can be done to the stock xenforo after installing it for seo purposes?
I see that the software is easy to install and almost everything works from the beginning, but there should be something that I may forget and thats not done automatically.
I have the content, I just will import it.
What I want to know is what I can better. For example do I need mod for meta keywords and description of all the topics and forums or is this done by xenforo?
And other little things I can change to make it better.
