read above .
basically you send pins/images and resend others images in a niche.
each pin niche belongs to a board , you have to ask to be accepted to a board, when accepted you get to show your / pin images to there users then do it all agin with there pins/images.
repeat.
to make a pin/ image make sure to advertise your business on it with a watermark.
your need a bot to do everything multiple times and accounts for more niche.
Pinterest is based on images talking and posting and reposting.
the majority of users are ladys .
many niches convert very well.
gd luck
that it nothink more nothink less.
ps.
all accounts in a bot need there own ip.
when showing a link on your pin/ images need to drive them to a lander then main website.
