How SEO is Presta 1.25/1.3 out of the box?

Hi,
How SEO is Prestashop out of the box? I only ask because I have another website made with Actinic, it was mainly HTML based with not much dynamic scripting and PHP content and it is the number 1/2 for most of my main keywords. It is a specific target market but it beats other sites using OSC, Zen cart and others. I have not added any special meta tags or special coding, just out of the box with my site products and very minimal content. Is it the HTML core? The shops it is competing with have maybe 50-75% more content and more products.
