Comparing websites on google trends show us that if anyone were to reach as many people as you find on STEEM, you would have to pay about $50,000 per day in ad cost.
Hopefully enough people will buy your product to go break even with the marketing costs and a profit for all products sold above that threshold. On STEEM, most people have yet to discover the value of the vote, the value of trending. But that is OK!
The Blue is steemit.com and the Red is another website which we know the ad-prices with.
And with even more users/readers/viewers - the value of trending is even higher per day. In order to get to top trending, you will have to use the 7-10 biggest bots with the highest bid and it would cost you about 800 STEEM which today is worth about $340 all in all.
Now that is a lot less than $50,000, do you agree?

Maybe we should add a column extra to show theoretical value based on comparing with other similar trafficable websites, but until then - here is something for you to monitor:
