Salon.com will mine Monero on its visitors' computers to compensate for the loss of advertising revenue.

How does the income from such mining "ads" compare to the cost-per-clic or cost-per-impression of traditional display ads like Google Ads? We could assume that a typical CPM is 5-10 $ and the typical visit lasts 2 minutes for 1.5 pages.

Some visitors may prefer to donate some computing and electricity rather than have their attention and private data sold by ads which also consume bandwidth and CPU.

From Coinhive's front page:

Will This Work On My Site?

Technically yes, economically probably not. If you run a blog that gets 10 visits/day, the payout will be miniscule. For the captcha and shortlinks with a sensible hash goal (1024–16384) you'll need to have a whole lot of users to make this worthwhile.

Implementing a reward system for your site or game where users have to keep mining for longer durations is far more feasible. With just 10–20 active miners on your site, you can expect a monthly revenue of about 0.3 XMR (~$95).

If you run a streaming video site, a community site, an online game or anything else where you can give your users an incentive to run the miner for longer durations, then by all means: try it.

For the miner to generate a lot of revenue, you either need a lot of traffic (in which case, it might be more efficient to just use traditional ads anyway) or need to keep the user engaged with your application (so that you can keep using their CPU). 2 minutes doesn't look like sufficient engagement to me.

By the way, since the application want to keep you glued to the computer screen so you're willing to let the application sap your spare CPU, your attention is being sold (though your private data probably isn't).

    Thanks but I have no idea how to translate income for "10-20 active miners" to income per visit. If they mean users who mine 24h on your website (which seems nonsense), that would be something like 300k visits/month?
