  • Use <strong> and<em> tags if appropriate
• Optimize your URLs
  • Use Search Engine Friendly URLs (for dynamic sites)

  • Have quality content
• Use search engine friendly design
  • Create a human sitemap

• Create a page that encourages webmasters to link to your site
  • Provide them the relevant HTML to create their link to you
  • Provide them with any images you may want them to use (although text links are better)
• Make sure your website is complete before launching it

Immediately after launching your site you should do the following:

• Submit your site to all major search engines

• Begin a link building campaign (attempting to get keywords in the link anchor text)
  • Put a link to your website in your forum signatures

  • Submit articles to relevant websites

If you will pay to promote your website:

• Submit your site to pay directories
  • docs.yahoo.com
  • www.goguides.org
• Purchase text links from high PR (Pagerank) sites related to your site

Finally, as part of an ongoing strategy:

• Continually update your website will quality, unique content
• Continually seek free links preferably from sites in your genre

Do NOT do the following:

• Make an all Flash website (without an HTML alternative)
• Use JavaScript for navigation
• Spam other websites for incoming links
• Launch your site before it is done
• Use duplicate content
  • Point several domains to one site without using a 301 redirect
• Use markup inappropriately
  • Style <H>eader tags to look like regular text
  • Hide content using 'display: hidden' (for the sake of hiding text)
• Use other "black hat" techniques (unless you accept the risk - Banning)
  • Doorway/Landing pages
  • Cloaking
  • Hidden text
  • Keyword stuffing

Additional Tips:

• Usable and accessible sites tend to be search engine friendly by their very nature
• Be patient! High rankings don't happen overnight
• Don't obsess with any one search engine. They are all worth your attention.

In other words you have SEO in mind before you start your website. And only submit once you have a complete website.
