Like you I am a scientist and like you did in the past, I am currently working on translating great scientific literature into tips. In my case it’s child development research into play tips for parents. I can already see that the outcome of my experiment is going to be the same as yours. Great content but who cares. I hadn’t even thought about my key influences. I know some important ones, but don’t see how they would share my content. I thought I was writing content for my potential customers. Is your SEO that works course the same as the content that gets results course? Sorry if I sound a bit dim asking that question.
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.
Web traffic is the amount of data sent and received by visitors to a website. This necessarily does not include the traffic generated by bots. Since the mid-1990s, web traffic has been the largest portion of Internet traffic. This is determined by the number of visitors and the number of pages they visit. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth.
