I have build most of my business using the internet and I found
our that most effecctive is using facebook and google ads together
with capture pages and sequence of informational emails where
people can learn more about the business opportunity. Its important
thoug to create emails which will be really interesting and with
call to action, and contacts. Also using LinkedIN and facebook
groups as free source of leads.
Before you start with any MLM company I would suggest to check
if they are able to sell products around the globe. Some companies
will limit you to sell only in one country which can be limiting
for some people.
