So maybe it isn’t as hard as everyone makes out, or is it? I have been running a campaign for about a week now and here are my stats:

Expenditure: £7.36
Income: £105.00
Net: £97.64
ROI: 1327%

These results are mostly fluke but partly due to timing, but still far to early to tell. I am sure the ROI will come down a bit, maybe about 1000% or so

My only problem is now volume - it’s time to rinse and repeat x3.
