How would you monetize these? Mostly from just adding Adsense to the page? [For example, I'm looking at the geolocation of #hate/#love tags, and the imbored-counter.]
I have had a website in the barcode niche and the click was as high as $5-$7 with a 2-3% conversion ratio. That's like $15/100 visitors only and yes I was making that much.
You can check the PPC in adwords for scanner tools, it's exteremly high.
