Site is on Google Page 5... How to Raise It?

Hey everyone. I have a website built on an exact keyword domain that receives about 20,000 exact searches per month. It used to be on page 1 of google fo the keyword but has slowly slipped to page 5 and traffic has slipped proportionately. I would like to get it back to the first page. The cool thing is that it is on page 1 of Bing for the keyword and page 1 of Yahoo for the secondary keyword. So any tips you have would be greatly appreciated. Im going to start with adding some fresh content. Im sure that will help a bit.

Get more links to your site with the keyword in the anchor text.

wow.. you wasted the chance man.. once in no.1 you should have solidified your place with loads of quality links... its not too late.. go for a xrumer blast.
