you can start from.

Database driven websites often come with their own unique set of SEO related problems. Over the years I’ve worked with a number of different CMS and never have two been exactly the same. Some are more SEO friendly than others, and some are easier to alter than others.

The basics needed for SEO is the ability to create default, dynamic title and description tags, with the ability to customize on a page by page basis as needed. Control over breadcrumbs, image alts, and editable body content that isn’t tied to a manufacturers database is a must. Being able to dictate URLs can also be a sticking point for some systems. Basically, it comes down to the ability to control and customize the environment.

Clean and lean code can improve website performance issues more than most people think. Bloated code can slow down both spidering and page download, both of which can have an impact on a site’s search engine rankings. If the developers use poor coding practices, your visitors won’t see it, but they’ll feel it as usability is diminished on top of everything else.
