The past 2-3 years have been a huge learning curve and trying new things every week thought me a lot so I would do a number of things differently if I started over:)
– hire help and outsource tasks much sooner (writers, SEOs etc)
– do market research more in-dept before jumping on a niche
– never use trademarked domains
– create multiple income streams for my affiliate sites sooner (diversify revenue sources: rev-share, CPA, fixed fee ad campaigns)
– invest in powerful software to scale content and marketing
hope this helps someone who is starting out.
