The revenue that you can generate from these smaller niche sites will be much higher. You do not have to spend on advertising your site. Visitors will be entering your own website and there is a large probability that they will be clicking the ads that are displayed in your site. So what is this niche? This is the selection of a particular topic with exact keywords that Adsense will pay you premium when a visitor clicks on that particular advertisement. It may not be the most trafficked site; but remember Adsense is serious in paying you once a visitor is interested on it and click their ads.
