This is an important distinction to remember as so many people get obsessed about ranking first on the Index (home) page for the most competitive high traffic generic keyword. Because people increasingly search the web by using very specific keyword phrases and not just competitive, generic terms like "Phoenix Homes for Sale," your home page is not the central entry point into your website. If you check your web logs, you will undoubtedly learn that your customers are finding your site on a page other than your home page. You might think of it as having many doorways for visibility instead of just the front door.
Every page of your site should be prepared to serve as a potential doorway to your site
Since today's homebuyers search on the web with a great deal of specificity, every page of your site should be optimized for a different keyword phrase, thus presenting numerous doorways to your site. In fact, my site, which wins first page placement for all of the major competitive keywords like Gilbert Real Estate and Gilbert homes for sale still wins eighty percent (80%) of its traffic on other pages that are optimized for long tail keywords.
So, don't get stuck thinking of your site as having only a front door that people enter and then go to other pages, but consider the potential of aggregate traffic by offering hundreds of doorways, each optimized with very specific keywords that are subsets of your primary keyword.
Of course, it helps if your real estate technology automates the process of creating, optimizing and organizing the hundreds of pages with long tail keyword phrases. This is more easily done than Realtors may realize. Just make sure that your site's technology "functionally" incorporates all of the MLS listings into your site and organizes them by themed category.
