Successville  Resources To Get You Here 
Directory Submission
If you want you site to show up in searches, it has to be submitted to the search engines.  The best program we have found to automate the submission process is Directory Submitter.

Social Networking Sites
Social Networking is the list builder of today.  These networking sites can either provide you with high potential exposure without direct income, or they can provide you with less potential exposure, with income for generating referrals to the site.
Recommeded: 

Sta.rtUp.biz is the best I have found if your purpose is building a business.  Unlike the other networking sites, the people here are here to find or build a business, and not just to have some one to talk to. 

The Rest: 

ZenZuu seems to be the best for making money at this time, but Facebook will probably generate the most contacts.

Article Marketing Sites
Article Marketing is an easy, but not always so quick, way to build links to your site.  There are literally thousands of sites that will welcome your unique content articles.  My recommendation is that you use one of these as a "base" site, and then use Unique Article Wizard to automate propagation over hundreds more.
Recommended:

EzineArticles.  has a large audience, and is a good place to start.

The Rest: 

Whether you are looking for a niche market, or for overall exposure, Unique Article Wizard will do all of the research for you.  They keep up to date on what's out there, and you can choose the sites and directories you submit to from there.


Safelists
Spam is the biggest no-no in building a business.  Even if you buy a list from someone, you can't email them directly, because you have no prior relationship with them.  Safelists provide an almost unlimited number of people who have opted in to receive communication from your business.  WARNING: Create a junk email account before you sign up. I signed up for four of these, and in two days was getting a consistent 600 emails a day. I am not a fan of any of them.

Traffic Exchanges
Traffic Exchanges give you a way to exchange traffic with someone else.  "I'll look at your site if you look at mine."  Generally, they can create "illusion traffic."  You get a hit, alright, but it's the same kind of hit you give them.  Click, wait the required amount of time-- usually about 20 seconds-- and then go to the next one.  Traffic exchanges are not rated, as they seem to be fairly equal.
