Tip #1:
Add a lot of content to your website. Preferably in serviceable English, well written, and cogent. You want to get about 10-30 pages of new content a month, and, also very importantly, get this content linked to. If you write scholarly papers, you can get yourself linked to by .edu and high PR sites, which will sharply boost your site. Finally, by honing in your articles on specific keywords, you can target new areas and reap niche searches.
