Totally depends. Use the keyword tool as a guide.
In the past, I only got as far as single page sites then lost focus. Most disappointed but some earned maybe 50 cents a day. Not bad for a single page.
Now I'm starting again. It's essential to avoid the clickbump look and also to avoid doing only one page if you want to survive, besides it makes you more.
Me personally, I'm going for a minimum $1 CPC and 1,000 exact monthly search.
Theoretically, say I get 10% CTR and capture maybe 10% of Google traffic (rough figures, don't take them as gospel), that means I get per page:
$1 * 0.1 * 1000 * 0.1 = $10 per month per page. Probably I would even get less than that.
Let's call it $3 or $4 monthly income per page.
The more sites and pages you have, the better.
Even if you assume a buck a page, then 1,000 pages brings you $1,000 a month.
I have over 1,000 articles rotting on Ezinearticles and making Chris Knight some spare change. I should've stuck to my own thing.
Of course, none of this assumes any promotion. I hate promotion. I also don't want to try anything ultra-black hat in case of loosing my Adsense account.
100 sites is my target and 10 pages of content on each. 8 sites with one page content so far, 9992 pages to go.....
As for your 22K searches keyword, something tells me that, despite the CPC, there is something "wrong" with the keyword. It is hard enough to find keywords with even 2 or 3K searches these days, let alone 22K.
