Submit Your Site to the Right Directories
Submit your website to the open directory project, if possible. Google considers this directory to be an important link. Be patient. A real human has to check your site, before it's listed in the Directory.
Submit your site to specialized directories. For instance, a work at home mother owned business (WAHM) should submit her site to WAHM directories. A site on butterflies should be sent to biology or entomology directories.
Don't get too submission happy, though. Google, in an effort to combat click fraud, often filters out websites linked from link farms, or pages with nothing but links to other websites. This is one reason why free services to register your website may hurt you. Stick to specialized directories and organizations. They're more likely to help and not hurt your rankings.
Social Networking
Social networking sites can be a good way to promote a site, but not all of them will affect your rank directly. Digg and Del.icio.us are social linking sites that could potentially have the most impact.
Make Your Graphics Search Friendly
Keep the Flash to a minimum. People may enjoy reading Flash, but search engines tend to skip right over it. Google has gained some ability to read Flash, but it is still limited. If your menus are in Flash, they might as well be invisible. Consider making plain text links in addition to or instead of Flash.
Give your images <alt> tags. Not only does it make your website more accessible to the visually impaired, it also gives you another chance to place your keywords where Google can see them.
Good Design Is Popular Design
In the end, strong, well organized pages are pages that Google tends to rank higher. They're also pages that tend to become more popular, which means Google will rank them even higher. Keep good design in mind as you go, and much of the SEO will design itself
