Computerworld published an article regarding some interesting comments from Matt Cutts. The article mentions Matt and some freely offered clues, “such as placing keywords in the title, headings and even the URL, and keeping related words close together.” Hint (LSI).

Keywords in the title, description, headings and url are a standard practice.

LSI (Latent Semantic Indexing) is a fantastic tool and in many cases, if you are knowledgeable about your topic, you may find out that the LSI is already in place when the writing is complete.
