What is the difference between an Affiliate Link & Custom Link?
AFFILIATE LINK :
In your regular affiliate link, partners will be under you directly.
CUSTOM LINK :
Custom link is a team link - new partners will register to your existing partners one by one. You can choose specific IDs and types of spreading manually. An upline with 5 or more members (downlines) can provide his partners with custom link for others to use. This will grow your downlines and auto place them sequentially within your existing partners (downlines) .
In essence, these links are more into sharing, teamwork or building your team.
