All the top KWs are still there, but tens of thousands of those that used to bring 10-20 visits a month or even less are no longer there. Likewise, all the top traffic pages are still top pages (and number of visits is roughly the same) but those pages that were visited just a few times a month now get no traffic at all. Given that there were thousands of those, the effect on overall traffic amount is considerable.
Google changing how they detect user intentas it is important to us and probably others.
Google adds the qualifier but your pages cannot rank with the qualifier and therefore you don't see anything in the logs because there are just no visitscorrect ! unless the [placename] has no OFFICE, in which case we get on page 1
