How do you target popular keywords without keyword stuffing?

Other than trying to repeat the keywords I want ad nauseum, what is the best strategy for optimizing for a fairly popular keyword? Make sure it's in the domain name? Every title? What else?

 

Put the keyword in the article title, and in the first sentence of the article - and after that write as normal.

 

Write convincingly.

 

I wouldn't put it in every page title.

Make sure it's in the pages' meta keywords, is in the article title, and that it is used naturally but often in the actual content.

 

werd -- each page should have unique titles

if I'm doing a site and part of it is a 10 page tutorial, each page has its own title and isn't grouped into "how to blah blah" but "blah blah step"

most of them also only have the site name on the homepage as well, but it depends

 

Yes, exactly.
