New website design - Critique

Hi there, are you the designer or the developer? or both?

Development wise, lets start with < p > for Paragraph and < ul > for Unordered List, so maybe you would like to change this:

SEO - Search Engine Optimisation
<a href="seo1.html">
CSS - Cascading Style Sheets
Long term success
Online advertising
Online marketing
Website hosting
Tracking your websites progress
<p> </p>

to something like this:

<li><a href="seo1.html" title="SEO - Search Engine Optimisation">SEO - Search Engine Optimisation</a></li>
<li>CSS - Cascading Style Sheets</li>
<li>Long term success</li>
<li>Online advertising</li>
<li>Online marketing</li>
<li>Website hosting</li>
<li>Tracking your websites progress</li>
