GetSimple has many features designed to help you optimise your site for better search engine rankings.

Google Webmaster Academy is a good authority for what's important in basic SEO.

The GetSimple Default themes provide individual pages with html titles in the format Site Name - Page Heading exactly as suggested by Google. If you don't want to be tied to that format you can change it by editing the template or install the Custom Title plugin which will allow you to write whatever you wish in the title of each page.
