So how are you monetizing if not via adsense?
For instance, while working in tax law for a number of years, I created an annotated Google Custom Search Engine for my own research purposes.
As evidence that it's an under-served niche, the website where it's published was cited by a UCalifornia Law Library and a number of other related websites as a useful resource for tax research purposes.
Besides adsense, how would you generate income for this?
You have the terms people are searching for, just match a book to the term and offer to sell to them. Something like that, but I have no idea about the market.
From your post above: I don't really know how ads work, so I've never actually used them.
Huh? Which one is true?
