Add a general block in the SEO page, no style, with explanation such as

SEO Permutations Hidden on the Landing Page
The next block, in pink, acts acts to generate N versions of your home page (where the block below is mirrored), each with one permutation from the article categories.

Insert an articles block in bulleted view, set style to pink. Title: "Special Search Term Target Page Generator"  Enable Categories, see it to "Maximum # Articles" to 300, Set "Summary" to intro+body, in view options click mouseover, intro only in pop-ups.

Add up to three catagories such as "location" and "service". Two catagories is the most common.

Mirror the block to the second column in the 2 column "Home Page Top SEO Text" container added above. In the mirror, unset the title, unset the pink style, use content rotate view, save.  Configure the mirrored copy and click in the view preferences "Show Title" and "Link all articles for SEO".   (You do not have to put it here, sometimes it might go into a sidebar or such, but this is a good start.)
