One of the most common preconceptions with SEO is that if you optimize a site for the benefit of Google then you will rank well with other search engines. However, the big three search engines (Google, Yahoo, and MSN) all use different algorithms that demand different things. Google has a mixed bag but certainly leans towards inbound links whereas Yahoo loves keyword dense content sites. This leaves us with MSN, whose primary consideration when determining their search results seems to be heavily based on internal linking structure and inbound links. But these are far from the only SEO techniques you need to consider.
