Do you mean what is the most profitable industry/topic area for adsense?
It is usually a trade-off between how competitive a topic is, compared to how profitable it is.
For example I have tried both dating and real estate and found that per click real estate is a higher return. Dating seems to vary per click, but also the nature of a dating site does not seem to lend itself to high click through rates.
Although, maybe its my site design of course! Dating in local areas is also easier to rank for than equivalent local real estate terms.
The most profitable online topics - gambling, pharmaceuticals and pornography - are so competitive and prone to spam that these ads are not allowed in the G system. Also they raise other ethical issues.
My advice, pick a topic you are knowledgeable about...
