How do businesses advertise, market, or promote themselves?

[Magi]

on MySpace, Face Book, youtube, etc?

Please give me links to businesses that are doing this.

This sounds like marketing class question...
Businesses have to be careful promoting in social media so that they are actually making connections with consumers, vs. just talking to themselves. If you go on the three social mediums mentioned and put in the names of some of the products that you use, you'll find plenty of examples of companies doing a good job and a poor job using these mediums.

In order to be successful on the Internet, you must submit your websites to the top search engines and directories. If you are doing nothing else, search engine placement and keyword-related advertising can make up 80 to 90 percent of your traffic.

Submitting to 1000's of "search engines" is not the way to get your website out there. Less than 100 websites receive 99% of the search traffic. The other thousand are harvesters of email addresses and use their submissions to find prospects for spam.

http://www.betterrank.com have chosen the top 66 search engines in order to achieve maximum results. When you submit to these 66 search engines, search results will show up in hundreds of other engines. For instance, Google powers the Yahoo search engine. Search listings in Google will show up in Yahoo as well. Why would you pay £299 to Yahoo when you can get listed in their directory by submitting to Google??
