As you change content on your website make sure that your keywords (phrases) continue to be used effectively. This is particularly important on your key pages.
Review your keywords by checking your website statistics using Google Analytics - what are people searching on to find your website? Check out your competition - what keywords are they targeting? Are they higher up in the search engine rankings than you?
More information about: defining keywords and using keywords.
Also make sure that you update your metatags along with your content. Page titles and descriptions are displayed in search engine results. They should be unique, contain keywords, accurately summarise the page and persuade people to click to visit your website.
