When it comes to online businesses, you hear of many entrepreneurs who become dependent on one source of traffic which usually is organic from Google in most cases. The problem with that is that Google runs major algorithmic updates periodically throughout the year so your site may drop off or even disappear off the results at any given time. One of the most solid sources of traffic has and always will be through your own personal list of subscribers in the form of an email list. Your email list usually holds its weight in gold as the people who opt-in not only have a vested interest in your offering, but also are more likely to engage and purchase. Matt Paulson has several diverse online businesses in different verticals but the common success factor is his email list which is now over 150,000 in subscribers but also worth over $1 million in sales. As they always say, the money is in the list!
