Perhaps you have too many keywords? It would be better to focus on a smaller group at once - perhaps only 5 or 6.
I agree with the main advice given by lots of others: 1. Keywords must be RELEVANT to your sites content. 2. Spend mmore time on your keyword research BEFORE you write any content. 3. Start by off page promotion, eg blog posting, rticle writing 4. 39 keywords is far too many. Oh you'll be found by Google, but probably on page 432 of search results.
