There are many ways to make your real estate website more effective, however here I just want to speak about the basics. These are of no particular order although usability is number one for a reason.
The majority of visitors to your site come to get property information, so make sure you make it as easy as possible to get to the information they want. If you have less than 50-60 properties at any one time, ditch the search facility and just provide a nice clean informative list of your properties. In other words, don’t waste your visitors time. A user of your site should be able to get whereever they want on your site from wherever they are.
