A variety of methods can increase the prominence of a webpage within the search results. Cross linking between pages of the same website to provide more links to most important pages may improve its visibility. Writing content that includes frequently searched keyword phrase, so as to be relevant to a wide variety of search queries will tend to increase traffic. Updating content so as to keep search engines crawling back frequently can give additional weight to a site. Adding relevant keywords to a web page’s meta data, including the title tag and meta description, will tend to improve the relevancy of a site’s search listings, thus increasing traffic. URL normalization of web pages accessible via multiple URLs, using the "canonical" meta tag or via 301 redirects can help make sure links to different versions of the URL all count towards the page’s link popularity score.
So as you seek ways to better influence your online presence you should remember to look at a variety of internal site features and not just your external aspects.
