Yes google treats each individual page of your site as an individual website and as such each page of information should be optimised for one search phrase or word.Would this text be just as google-friendly on an about me page?
If you are lucky enough to get somebody to link to you (which is equivalent to gold dust now!) you shouldn't necessarily just link to your homepage you should get them to link to pages within your site - which is called 'deep linking'. Crikey - all highly technical stuff
