Affiliate marketing will take time to build the audience based on your niche so it's not going to give you money from the day you start and I won't consider it as a business rather a job cause we are just part of promoting someone's product or service not our own.
You can see people say that every successful company started with zero capital but it's not entirely true, they started small with their money or taking loans then once they reached a position the investors were ready to throw in money that took those companies to next level, so starting with $0, is far away from reality.
That's right all along,ordinarily,you'll find it difficult to build an active fanbase or Audience and you'll require some certain skills that'll enable you to develop and converse properly to customers.Normally you would require skills,business options and several other strategic plans together with marketing tactics for a successful business build.
But there's actually what they call DROPSHIPPING these days and i mean that's what most people used to build a strong marketing network,specifically using/exercising the rights tools for promotion and the business upgrade.It's just you advertising someone's else's product,adding your profit to the actual price and whenever you get an order,you act as required and that's it.And thats how some persons have been able to capitalize for thier business initially.
So starting a business without capital truly exists and its that simple.Your're starting a business without capital works when you utilize your unique talents,efforts and your ability to meet up several requirements.
