lists vs dl and seo

I want to create an unordered list of facts as links.  Each link will have a paragraph  or two of supporting text. The list will be rather lengthy 10 - 12 or more items. From a search engine ranking perspective; what is the best way to present this.Should each link go to it's own page.  Should I use hidden divisions that show when the title link is clicked?  or something else. <ul>     <li><a href="">Fact 1 title</a></li>     <li><a href="">Fact 2 title</a></li>     <li><a href="">Fact 3 title </a></li>     <li><a href="">Fact 4 title</a></li> </ul> Fact 1 blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah Fact 2 blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah</p> </div>
