Are you using bitcoin plus on your website or running it on your own computer?
If you are running it on your website and crowd sourcing the mining, then it may work out for you.
But take into account that you would need a sizable amount of traffic to your website and users need to accept a big ugly popup that warns them that a script is running on your website.
If 1 million people visit your website for 100 seconds each every day, that's a 100 million seconds at 0.5 MHz. That's roughly 600 MHz, or less than 1% of an Avalon GPU. You'll get less than 0.05
BTC per day.
