It appears, from the numerous excellent comments to the FreeRice article, that I made, well, a formula error in counting grains of rice, and it also appears that my estimate of cheapo CPM rates is perhaps, well, far too high.
I really should have done a proper spreadsheet rather than use the calculator on OSX. So I’ve just done that.
Luckily those errors are both in the same direction, so Mr John Breen is still in the money, though just not as much.
New Rice weight: 1.2 billion grains = 31.2 tonnes = which at $350 per tonne costs $10,900
New CPM rate: is $1, so income is $130,000 (double for CPM of $2 obviously)
Profit: $120,000 odd. Not a bad little earner. But let’s get the latest data..There are now 3.25 billion grains of rice given out, so let’s call that 350 million page views. Just pause and think of that – from launch on the 7th of October until the 21st of November there have been 350 million page views on this brand new site.
The web is still amazing.
Now 350 million pageviews = at CPM of $1 (per the comments) is $350,000 in income. Not bad, and it could well be double that or more.
Meanwhile those 3.25 billion grains of rice weigh 84.7 tonnes, which costs arond $30,000.
So a net income of $320,000 for Mr Breen. Very nice income for a month and a bit.
