From ClickZ, Real Estate Developers Need Web Marketing Strategy:
Perhaps because of the tricky mix of objectives, or because development projects typically take longer to create and sell than single-family homes, developers are even further behind on Web marketing. They’re uncertain whether to build slick, glossy sites with clever tools, or build functional sites and dedicate more dollars to online advertising and marketing. Many are certainly considering search marketing, but few seem to understand search engine optimization takes time, perhaps longer even than the life of the project.
