Including maps on your website can make it easier for people to find each and every real estate property and the consumer can learn about the real estate developer’s portfolio. Website designers and developers usually create maps using all image files. Image maps can create accessibility problems to your website for search engines. To create readable image maps and have your maps findable by search engines create text link navigation for each map.
An HTML alternative is to create text link navigation by using, alt tags, poly coords, text links, title tags, and long desc to link the image map to an unordered list.
A CSS alternative is to use a CSS based map where the accessible map data is separated from the visual display of the map.
