If you are a real estate professional specializing in one area, you may want to limit the areas that are searchable on your MLS search pages. There are two main reasons for restricting your search area:
The first reason for limiting your IDX search page to a certain area is that it will only show the area that you specialize in. MLS data often covers a wide range of territory and you may not want to travel to show homes that are sometimes hundreds of miles from your location. By restricting your search area, you are limiting your website visitors to the area in which you specialize and can offer the best service.
The second reason for limiting your IDX search data is for website usability. Loading all the data in your MLS takes time and the more data there is, the longer it will take to load. This issue is especially noticeable with large MLSs and on the Map Search page. By restricting your data, your search page performance will be much friendlier and quicker.
