Clickz pointed me to the test being done in NY for hotels in Manhattan. This is expected, and not a huge shock, but what will be important for the future is the use of LOGOS in the details area.
Oddly, in the test, the little details page that pops up did not link the URL shown. So www.holiday-inn.com was not linked in the little box. The title, however, was redirected to http://www.ichotelsgroup.com/h/d/hi/1/en/hd/NYCBY.
A click on the sponsored links in the left side of the box ONLY brought up the map bubble, and did not bring up the site, and there were no alternatives to that other than to then go over to the bubble and click. I would have hoped for a rollover affect to SHOW it on the map and a click-to-site effect on the ad. The question is, will advertisers pay for the map data display or the second click on the header?
