The long time fundamental element of "Link Content" has become mission critical because Google, Yahoo and MSN don't trust the integrity of sites anymore.

These are consequences of SEO (black hat) developers that have ruthlessly manipulated every possible loophole to dominate search engine rankings.  So Google (followed by Yahoo & MSN) employed the standard that if a keyword phrase doesn't appear in external links to your site, you're not ranking very well for that particular search term.

It is rare that web users search for us specifically, using personal or business names. So links to real estate sites should indicate what we do and where we do it.  Like "Seattle Washington Real Estate" or "Real Estate on Whidbey Island Washington".

This is a big reason many established sites have experienced a sharp decline in rankings.  Most incoming links to these older sites use "Link Content" based on their business name, not keyword terms that visitors are searching for.
