SEO: run a search on Yahoo.com for site:your competitor's sites, or people who rank highly for the keywords you want to rank highly for. Look at the inbound links coming to these sites. Figure out why the site that links to your competitor should also link to you, and then tell that to the site owner. The biggest grey hat SEO technique right now is "articles." You write or have written articles about some topic relevant to your site. You upload these articles to article directories, with the terms that the article must include certain links back to your site. People trying to get content on their site repost your article, and you get links to your site.
