Here is a list of personal tips in publicising a website, and making it search engine friendly . Consider them carefully. Consider adding a tracker with a referrer script to see how people are presently finding it, and what words they used in search engines. Try to include the very most important keywords between the title tags in the page head. Include keyword and description tags in the head also.
Some search engines no longer look at meta tags, but some still do.
However, do NOT abuse the keywords tag, keep them sensible. First paragraph, and first page. Try to incorporate keywords into the body of the home page if possible, especially in the first text paragraph. Also keep the home page light - watch file sizes. Avoid frames on the home page, or add a frameless home page as an intro to a frameless site.
