Size of a term to make money off of ad based informational site

[BobGW]

Hello,

I am used to estimating how much money is possible to make out of ranking for Ecommerce terms. Higher price products have a lower conversion rate  (cheap items are opposite) so you can look at the keyword size in keyword explorer and estimate pretty well (roughly).

My question is, how many times bigger does an ad based (informational) keyword need to be to get similar profit?

This is just an estimate.

For example, does a term need to be 5? 10? times bigger on average (volume) as an informational keyword to make the same amount of profit (roughly of course)? I realize there are many factors here but you must have some way you think of it?

Can you give me some general guidelines?

It really depends on the website, the content, and the types of ads.

Most large content sites I've worked with we're in the range of $0.10 to $0.25 cpm in AdSense.

I was not talking about PPC. Maybe I misunderstand.

I was talking about getting thousands of visitors and placing a single ad on each page with a 3rd party ad company for revenue.

Hi Bob,

Even roughly, this isn't something I could do. If a click is worth $1000 and you have to pay $50 for it, you might consider it a worthwhile gamble. If it was going to cost you $400 for the same click value, you might not think so.

There are no general guides on this I'm afraid - just what you are happy with, within the realm of sensible costs that is. I can only advise that you try to get the biggest bang-for-buck. Choose phrases that are cheap but added together, will net you a decent amount of clicks for not very much money.
