$10 was an example price, but for most small sites you can't expect to make hundreds (or thousands) a month. I consider 'small' less than 1k uniques per day.
How you display the ads largely depends on your site and traffic. If you're only receiving a couple hundred pageviews each day, you'd want to have that ad showing as much as possible (to get a better price from the advertiser).
For a lot of these ads, you'd have multiple placements. ie. 4 ad spots for 125x125 pixel banners. On a site with a couple hundred pageviews it's realistic to assume you could get $15 for each of those ads (depending on the topic).
You're delusional if you think Adsense or other advertising networks will make you more than $15/mo. You're lucky if you get a $1 CPM (cost per 1k views) with most networks, assuming 6,000 views/month on a small site (~200/day * 30) - you can do the math there.
Again, this varies depending on the content. I worked for a small content network and we could charge $500/mo. for a banner spot that received about 20,000 views per month. But we only made $100-200 max with Adsense (across the whole site - roughly 45,000 impressions a month).
Just to chip in here, I know you were saying "I consider 'small' less than 1k uniques per day." to give an example, but this example is also most likely assuming you don't have targeted niche specific traffic. My 1K uniques/day pop culture tech/media site makes as much money as my 100 people/day very focused site on Apple products. Both are still serving Adsense only though that is only because I haven't gotten around to changing the latter site's advertising.
Also, $1 CPM with Adsense? If you are mainly a content based site (i.e. blogs) and place say two Adsense ads in prominent locations and maybe one Adsense link ad, you should easily top $5 CPM. I usually stay between $5 to $10 CPM for wordpress based sites.
