Syndicating posts to Social media any cost effective solution?
So I would like to syndicate about 100 pins per day to the biggest Social Networks like Facebook, twitter, reddit, stumbleupon, pinterest, etc...
I am testing onlywire but its not cost effective, because if I want to syndicate 100 pins to 5 networks it will cost me 500 submissions per day, so 15k submission per month and that will be extremely expensive.
I have saw another website that does this but limits the number of post per project, and I am thinking in growing a lot , so to have the ability to syndicate 400-500 pins per day per network.
Any good recommendation?
thanks,
