Another thing is sitemap , i think a website that is atleast three months old should create a sitemap .
Also one thing that SEO's warn today are the methods not to use of cheating the search engines that people generally use in lure to getting up there as fast as possible . Commonly people hide the keywords in same color as back ground ( a thing in bad taste ) , bombarding too many keywords in a single page etc . the disadvantage of such will be that your site may even be blacklisted .
