When optimizing a site, it is important to ultimately focus on the end user’s needs and not the needs of web spiders. While the search engines play a large role in determining a site’s relevance, it is important to remember that Google and Yahoo!’s main goal is to provide their users with quality results. So, a truly optimized site should aim to accomodate a site’s target audience, not the search engines. One cannot ignore how a search engine spider views the world, but websites are not targeted toward web spiders. True optimization is trying to make a site as relevant and easy to navigate as possible to a specific target audience – that’s what both humans and spiders are looking for.
