SEO basic's start with the html code on your page,  yes the raw page code itself. Html tags are an important part of your design for this is what the spiders and crawlers from the search engines will read. I would advise validation of all your html code before procceding to assigning elements to the tags. One big mistake I see in a rush to be on the internet is people forget to take care of the meta tags also, undefined tags do you no good during a read by a search spider. Now take special care in the design of a menu system.  As to have a good linking structure, do not round-robin the linking trail. Pages added need descriptive descriptions, many keyworks, a revelant title , revelant title Hmm what revelance ? You should have used the html tags H1 to assign some text, this text should cross reverence to revelant content. This is a big plus for your site pages to be seen as having a topic now for the search engines will know how to place and read your site. Even more revelant content is good, but the rest of the content text should be have a keyword linking structure.

  Next now that your pages have good html code, (validate)  assigned tags and you produced some content for our page we need the description and keyworks for the meta tags,  I see this total left off many sites unbelievable, The search engine's are going to send you traffic based on the keywords you have place on the page, so keep the description and keywords revelant. The keywords you think work are a maybe at the best, useless - Overture Keyword tool. Do your homework here and it will payoff. To get a search engine to see your site place a link on another site's page with a good RP ranking in a few days google will be cruzing your site also....
