A rough what-if estimator for ad earnings — not a prediction of real revenue
There's no way to know a site's real click-through rate or cost-per-click without actual traffic and ad account data — so this tool doesn't pretend to. It simply multiplies the three numbers you enter (pageviews, CTR, CPC) using the standard formula, so you can play with "what if my CTR were higher" or "what if CPC dropped" scenarios.
How to use it:
No — this tool has no connection to any ad account or real traffic data. It's a plain multiplication of the numbers you type in, useful for exploring "what if" scenarios, not a forecast.
They're just reasonable starting placeholders since real CTR and CPC vary enormously by niche, ad placement, device mix, and country. You should replace them with your own site's actual reported numbers if you have them, for a more meaningful estimate.
Real ad revenue is affected by traffic geography (advertisers pay very differently by country), seasonality (CPCs swing around holidays), ad placement and viewability, ad blockers, and the specific advertisers bidding on your content — none of which a simple formula can capture.
