The Goal Of Internet Marketing
The purpose of all internet marketing is to get a return on investment. The highest motivating factor is going to be money. IM and SEO are fun, but if you lose clients, or don't have the resources to do what you want, it can leave you dry and burnt out. SEO has made the internet way better than it ever has been.
The updates by Google have stopped all the spammers from polluting the internet with mediocre, or just plain ugly, websites. Now, websites are more dynamic and real marketeers are doing what they do best.
If you want to make money, just know that online advertising is a billionaire dollar business, and doesn't seem to have lack of momentum
