Once upon a time, https://tweepsect.com/ https://tweepsect.com/ would get upwards of 650,000 visits/mo so I slapped some Fusion Ads (now Carbon Ads) on it and it brought in about $200-300/mo. It has slowly declined down to tens of thousands of visits per month, which comes out to around $15-30/mo. I really didn't want to try and monetize it for too long and ultimately regretted not slapping a simple clean ad on it earlier. Could have made more with more non-exclusive ads but it was about right for the amount of effort it took (very little). Not bad for a completely unattended service with zero overhead.
