The short answer is ‘Yes’. There’s been a real change over the past 2-3 years in how web sites are treated by search engines, and that translates into a change in whether or not your site will ever get found in the first place. Like it or not, static sites (the old-fashioned business web site that rarely changes, however unique it may be) are getting almost completely marginalized by dynamic sites (sites with constantly updated content, like blogs). In short, anyone with 5min a day to update their site or blog can out-market nearly anyone else with a static web site that rarely changes.
