If you look at the theme file, you will notice that header.php contain less code and rest are in index.php, page.php and single.php
On our test we, have noticed that in this theme, pages load faster than normal themes where header.php has some heavy code. This makes search engine bots to crawl pages easily.
Also this theme is XHTML and CSS validated which is known to Search engine as properly coded sites.
We have incorporated jvquery.
You will notice that Page and post Title are not clickable in individual page or post. Its pure <h2> which helps in SEO of that particular page or post.
There are many other things we have focussed on making it SEO Optimized.
