This is what Matt Cutts - head of Google's webspam team has to say
Spotlight your search term on the page.
"Think about what people are going to type in to try and find you," Cutts says. He tells of meeting a chiropractor (a person whose job is to treat diseases by adjusting a person's joints, especially those in the back) from San Diego who complained that his site couldn't be found easily using Google search. The words "San Diego chiropractor" were listed nowhere on his site.
"You have to make sure the keywords are on the page," Cutts says.
When Google says something, it's time to listen.........and act.
