In the above example, the permutation generator will generate links for
Fremont hypnosis
Fremont hypnotherapy
Newark hypnosis
Newark hypnotherapy
But unless one of these links is followed the mirror on the home page will only show the phrase "Terms". What if you wanted the home page to show the "Newark Hypnosis" combination by default? For that you need to set the Default SEO Article.
Note that the home page can be set to show "Newark Hypnosis" if the domain is newark-hypnosis.com and to show "Fremont Hypnotherapy" if the domain were fremont-therapist.com
