I am in the process of planning a real estate website and we've come up against a bit of an unknown regarding giving search results to a user:
I ask this from the point of view of
1. would the user get confused that there are now two pages in front of them (though I think people are getting used to more than one window now?) and;
I also guess that this method is neater then a pop up but I am not sure is best mainly from a PHP query point of view.
Any help, comment, or better ways of doing it appreciated.
Both methods will work; which you choose will really be determined by your audience. The only way to find out which is truly best is to do a usability study of both options.
I know that wasn't the quick and definitive answer you were after... sorry. :) Here's an article that might help: Professional Website Usability
