- Make pages on your website with the word(s) in you want to rank for.
- Build links into that page from other websites.
It's not rocket science. I'm getting a bit fed up of all the buzz words - link pyramids, link prisms (????), super tiered ping extreme backlink blaster ultra (i made that one up)...
But it just comes down to using a couple of methods and building some links into your pages. Make sure your not building too many, and build them from a variety of places. (not all social bookmarks , or not all articles) - vary anchor text.
