WARNING!! Search engine submittals are not a magic solution to getting millions of hits, sitting back and watching the results pour in.  In fact, as the internet becomes busier, search engines are becoming less significant and website owners need to turn their attention to alternative methods of exposure for their websites.  

Some businesses need a website as an online service for specific known targets.  To these, search engine presence is unimportant.  To the rest, it contributes (by varying degrees) to the ongoing success of your business.  How much you should be investing in this aspect of your Internet presence is directly related to how important it is to you.
