If you do a search in Google like this "french connections"; you will see in first position a site with a bunch of keywords all linking to different page from the same site What do I have to do to have the same kind of effect/indexing for my site? Why does Google do that? See the result here: Thanks
it does it dynamically, a lot of sites (one of mine as well) got them in the last Google PR Update. There's no real tactic or tool to make google do this for you, but it generally happens if your site is popular and only when the user looks the name or url of your site up.
It depends not only Google, but mostly of our sites quality and popularity . I mean, that everything is in our hands.
