If you're interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
Really good article with some great tips. Affiliate marketing has the potential to earn lots of money and I'm hoping I can make it happen. I have tried the matched betting and it DEFINITELY works. The one thing I would say is that you need to check that any bets have been accepted by the bookmaker. I have had on occasion bets which look like they have been accepted but don't register in my account. Always go into your account and check outstanding bets or your bet history.
