good advice given. the main point in all of the replys is pretty simple, your traffic has to be targeted or you won't be making much if any at all. find a place where you have a targeted audience i.e yahoo answers and profit
ad placement is also very important. you have to keep in mind that there are certain "hot spots" that visitors' eyes are more focused on, thus, higher possibility for clicks.
Do SEO and get indexed in as many search engines as possible to pull up visitors. More visitors = More money. Also you can get back links from trustworthy sites.
Yes it is possible you can choose the high PPC keywords from it you can earn daily up to 30$ in one day. And also choose the keywords with low comparative.

in order to get $10 a day of steady income (meaning it is not $10 one day and $3 the next), you would need at least 8000 pageviews a day, which is very hard to do with a blog, and a waste of time when u compare other niches
Pagerank and earnings are in no way related to eachother mate Sorry if that demotivates you, but I just wanted to make sure that's said . Good luck with your goal, I think it might work for me too if I try it out
