Avoid some technologies
Everybody has to start somewhere. I remember trying to optimise my first site for search engines. It was a site I had written about 6 months before and I was pretty yound and very uninformed. I had written this site in one of the worst WYSIWYG site design programs ever (you can probably guess which) and even now I can remember just how difficult it was. Here are a few tips to start you on a journey considering Search Engine Optimisation (Optimization to those on the other side of the Atlantic).
I shall be adding to this as time goes on to hopefully become a useful resource to all. The one key point here is that it is normally much easier to write a page to conform to standards than it is to edit one later.
