After choosing two to three paid or organic
keywords for each page, try to integrate them into key paragraph headers and some body copy. See how the page ranks for those terms for a predetermined amount of time, change it, and then test again.
In addition to keyword strategy, Norene advises Webmasters to write marketing copy--not just straight facts-as, no matter what the specific conversion metric is, you'll need to persuade visitors to attain it. Try to organize copy into small chunks so readers can scan the page for tidbits that interest them, and include links to relevant paragraphs, if possible.
