Once you have done SEO Level 1 you have embedded search bait into the tops and bottoms of pages. However, any particular page has the same balance of SEO terms every time it is seen.  If does not, for example, one time emphisize Fremont Stop Smoking and another time emphisize Newark Weight Loss.   It also shows the same content for all domains.    SEO Level 2 can cause the page, and the site title to change to focus on one set of terms over other permutations, essentially making hundreds of versions of the page.

SEO Level 2 requires that the site's price plan include Advanced SEO Capabilities.
