do automatic website traffic generators work?

[Steve]

They may provide 10,000 unique visits, but it won't be the type of traffic you want. If you are selling something or providing information your best source of traffic is via search engines of advertising, that way the visits are from people that are looking for a site like yours and will be interested in the content. 10,000 forced visits, or just visits by a non-human bot will be about as useful as a chocolate teapot I'm afraid. If you want more genuine traffic you have to look into SEO or advertising your site. There is no shortcut to getting the type of traffic that can benefit your website, or that will make you any money via adsense.
