A couple of considerations with caravans:
If you have a major city (like a super science center) trading with it is more dramatic.
Trade offshore has an increase.
Trade with a foreign civ has an increase.
Trade with a demanded product has an increase.
Trade with a farther distance has an increase.
(Other factors come into play -- direct roads & RR, and later which advances have come into play, superhighways, & airports; major payofss at the stage where large number of beakers are required.)
So what you may want to do is to send a couple of caravans to yor biggest city/capital, "rehome" them (push them into the city with 'keep moving', open the city window, click on the camel, choose 'support from here') and then ship them via boat to a foreign civ offshore. Some higher risks -- the boats and camels can sink and drown, but the payoffs can be worth it -- a couple of hundred for a moderate distance, maybe 400-600 for a demanded product between two size twelve cities a dozen boat rides away. A couple of times the first payoff was so great I delayed delivering the second camel because the first gave me the next tech.
