What form of online internet marketing is best for business?

[Jake]

Adwords or other sponsored search that gives you the opportunity to present your message to people actively seeking what you have to offer may be the best, but competitive biding has driven up the costs to levels only the more clever advertisers can profit from.

Organic "Free" search traffic can be the same or better quality, but getting onto the first page of search results where 90% of the action takes place is very challenging, really impossible for some fields with entrenched authority sites. Building search ranking, including getting backlinks from all the social sites mentioned, is a slow process and puts a business at the mercy of search algorithm changes, shile paid search traffic is more reliable and scalable, providing you can make it profitable.

The many other paid traffic sources, Facebook ads, Ad networks, CPV popup windows and media buys for the big boys have to be tested to discover which is most cost effective.
