Fiverr is fine as a lead generator, in some cases.

And far better to us a standard model of creating an Authority Blog or Podcast around your topic.

You'll work far less via Blog/Podcast + have far higher income, than trying to use Fiverr as a revenue generator.

You're welcome to book a call with me + I can walk through my experiences with different monetization approaches... as each niche + your expertise level + what you're offering (product, service, info) has to be considered.

Also your entire funnel, including continuity system.

Also your personality style (introvert/extrovert).

Also your Lifestyle requirements - hours/week work, monthly profit, health, happiness.

Many factors come into play designing your money flow.

I've been freelancing + running various businesses since 1974 + having a match on the above factors will have a far higher likelihood of success, than having many mismatches.
