It's easy to advertise for free on the Internet and to promote your website! You just need to know the keywords to use as well as the Internet sites where you can advertise for free that get the best results when people do searches for things on the Internet. It takes time to set up the ads and/or the websites initially, but you will get results if you use the right words.
One thing that is important is to remember is that people aren't going to be looking for you by your name or even the name of your business, but will be looking for the service or products that you will be providing in the location where it is most easy for them to procure them.
I have a number of small businesses that I run. Most of the business that I get is from the free ads that I have placed on the Internet as well as words that I have placed in my websites.
Some of the best places to advertise for free for your website or business are listed on the following links.
craigslist: san francisco bay area classifieds for jobs, apartments, personals, for sale, services, community, and events
(To use Craigslist, you just find and post on the one that is near you.)
