Buy leads from a lead selling site. These are supposed to be email addresses of people that have signed up to receive offers. You just have to watch that they have good fresh "double opting" leads of people who requested more information about your particular field or you could be marked as a spammer. Some of these sites will email them for you with your own email or you can buy separate leads and use a separate email site for the mailing. There are email programs you can use but then you have a problem that Internet providers usually only allow up to 500 emails per day, and if you're doing it every day they might (rightfully) accuse you of spamming and shut down your connection.
Brian, I’ve drunk your Kool aid! Thank you for honesty and transparency – it really gives me hope. Quick question: I am beyond passionate about a niche (UFOs, extraterrestrials, free energy) and know in my bones that an authority site is a long term opportunity. The problem today is that not many products are attached to this niche and so it becomes a subscriber / info product play. However, after 25+ years as an entrepreneur with a financial background and marketing MBA, am I Internet naive to believe that my passion and creativity will win profitability in the end? The target audience is highly passionate too. Feedback?
Not all web traffic is welcomed. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. There is also "fake traffic", which is bot traffic generated by a third party. This type of traffic can damage a website's reputation, its visibility on Google, and overall domain authority.
